Even if the script libraries are themselves just PHP scripts...not any

Hmmm....now I think I understand what you mean, but if I consider it in
the context of my question and with your above statement, it seems
contradictory. I don't think it's that you're misunderstanding me...I
think it's me misunderstanding you ;-).
Let me lay it out:
Say you create a set of class libraries, called PeterLib, and release it
under the GPL. I download these libraries...like what you've done...and
decide to use them in my development. Your library makes available a
class called FooBar that I really like, and I decide to make use of it in
a number of my own files.
So, one of the core files in my application contains:
<?
require_once("/PeterLib/FooBar.inc");
$myObj = new FooBar();
$myObj->getFoo();
$myObj->printBar();
?>
Now, futher assume that I want to sell my application under my own
company's license and I label all my files as such, but still retain your
GPL license it the PeterLib files. I rush to market and have an
overwhelming amount of customers in the first month.
Four issues:
1. Have I violated the GPL by distributing your code with my "propietary",
non-open source app? I'm still distributing source, but my specific files
(including a few that call PeterLib classes) are not GPL'd.
2. If I decided to only distribute my own source for money under my own
propietary license, but told my customers that in order for my application
to function correctly, they'd need to download PeterLib. Is this a
violation?
3. If the above are considered violations, I assume only using libraries
licensed under licenses like the LGPL or PHP would make it safe for me to
redistribute with my proprietary app?
4. How do the above change if/when I decide to encode my self-written
files with Zend Encoder?
Thanks very much for all your input. Very helpful. I really appreciate it.

John,
I am not an expert of copyright law and licenses, but this
URL might help you answer some of your questions:
http://www.gnu.org/licenses/gpl-faq.html
Specifically, look at the questions under the heading,
"Combining work with code released under the GPL", as they
seem to be exactly what you are asking.

attached mail follows:
Chris,
Sheesh. I'd read it about 5 times but revisited just now. Somehow I
missed the key phrase "which are themselves interpreted.".
Here's the full relevant excerpt:
"Another similar and very common case is to provide libraries with the
interpreter which are themselves interpreted. For instance, Perl comes
with many Perl modules, and a Java implementation comes with many Java
classes. These libraries and the programs that call them are always
dynamically linked together.
A consequence is that if you choose to use GPL'd Perl modules or Java
classes in your program, you must release the program in a GPL-compatible
way, regardless of the license used in the Perl or Java interpreter that
the combined Perl or Java program will run on. "
That answers my question. If following the scenario I described
previously, my code would have to be GPL'd as well.
Thanks!

Makes no difference. If you think about it, the GPL applies equally to
binary programs and the source code that produces them . . . so an
interpreted language is like the first part without the second.

Perhaps I read "use" more literally than you meant it. You can USE a
GPLed lib any way you want. If you want to DISTRIBUTE a program (to
include a script) that uses a GPLed library you must do so under the terms
of the GPL.
If that isn't completely clear, read on.

You may do that.

Maybe. It depends on what "my own company's" license says. Specifically,
if it is a "GPL compatible" license, then no. For a list of
known-compatible licenses see
http://www.gnu.org/licenses/license-list.html#GPLCompatibleLicenses.
In practice when you say "my own company's license" you probably mean a
proprietary license. That would be a violation.

I don't think that there is any way to be absolutely sure about that
without being sued. If you win, no. If you lose, yes ;-)
It /sounds/ like a loophole, since 1. you don't agree to the GPL to write
your program and 2. you don't distribute the GPLed code.
I think in all likelihood you would lose. Your program would be seen as a
derivative work.

Right. This (should be)/is a conscious decision that is made by the
library's developer. If they want to let you link at will they use the
LGPL, if they want to extend the copyleft to linking programs they use the
GPL.

This is an obfuscation utility? If so, the GPL excludes obfuscated source
code as "qualifying" as source code for the purpose of license compliance.
"Accompany it with the complete corresponding machine-readable source
code, which must be distributed under the terms of Sections 1 and 2 above
on a medium customarily used for software interchange"
I.e. you can't give someone a printout of source code or an image of the
source code, you can't provide it on 1/4 inch tape or a stack of punch
cards, and you can't run the code through an "optimizer" or obfuscater
first.

Jan, between "double quotes", several things are translated
this becomes
\t a tab
\r a carriage return
\n a newline
\" "
\\ \
There are more, see the documentation.
So to type \tab
use
' \tab ' (note that these are 'single quotes')
or
" \\tab "
attached mail follows:
You need to escape the '/' with a '/', as it is a special character.
So, anytime you run into an issue where it looks like PHP is trying to
interpret something you just want it to print. The best first guess is to
try and escape it.
Just Thought I would offer a little more explaination.

\t is a tab character. If you looked in your source code, you'd see a
tab there. Use "\\tab"

Can anyone tell me what may be wrong with my email configuration? I
am using Microsoft Outlook with a Microsoft Exchange Server. My PHP programs
can no longer send emails. They were able to before, seems like it stopped

I'm not sure how you are creating your array, but your resulting array
would look something like this:
Array
(
[name1]=>namevalue1
[a1]=>Array
(
[k1]=>value1
[k2]=>value2
)
[name2]=>namevalue2
[a2]=>Array
(...
You end up with a two dimensional array (avoiding the columns term) that
contains a name value and a values array for each entry.

Subject: RE: [PHP] Is this just not possible?? ..create new odbc
connection..please help
yep, I am trying to come up with a way to get data out of an access db on the users machine and load it into the mysql db on the server. The only thing I can think of is have the user upload their db, php then creates a datasource, pumps over the data, deletes the db and datasource. My only problem with this method is if the db is large it may take them a while to upload it. Any other suggestions are greatly welcomed. I want it to be a 'one click' for the users so I don't want to ask them to export it to another format before uploading.
Thanks, Eddie

Are you wanting to have PHP dynamically create ODBC datasources instead of creating them via the typical Control Panel method?
If so, and if possible, would be tricky, but I'll bet it can be done.

Sure, you could do it any way you want. One way or another you need to get it into a variable, so how you get the template there doesn't really have any affect on your replace function.
I'm using the file based template so it's easy for users to modify. I "read" the template file into the output buffer, then store the buffer into a variable and clear the buffer: ob_start(); include("templateFile.tpl"); $tpl_content = ob_get_contents(); ob_end_clean();
The template is now stored in the $tpl_content variable. You could just as easily pull the template from a database. For the template file I place "data tags" in it that I do a search and replace on. Some common "tags" I use: {::PageTitle::}, {::MainData::},{::NavBar::}
You should try to use str_replace instead of ereg_replace since it's faster. Both support arrays for the search and replace part, so you can use one line of code to do 30, 40 or whatever replaces. I create an array of my data tags and another array of the matching data, then do: str_replace($tagArray,$dataArray,$formTemplate);
I can then provide a user who knows HTML a list of data tags (the contract) that they can place in a template anyway they want. The whole idea is to separate your data from your code from you presentation.
Hope that helps.

Hi there, I've been using PHP for about 2 years now and absolutely love it! Our company uses it as our main development language, so far though, there is one thing that has been annoying me for a while now.. the following line of code will not work: $object->function1($parameter)->function2(); I receive a parse error when i try to call another function off of the object that function1 returns. I know this is possible in java: object.function1(parameter).function2(); VB: object.function1(paremeter).function2 and i'm sure C++, although i'm not too familiar with that language.

Everyone,
I'm stumped by this, even after searching the archives and the web, although I admit the solution likely is something very obvious.
I've written a function to build a string of "breadcrumb" links for a web site directory similar to Yahoo, etc. It queries a categories table recursively until it reaches the root category, building a string of categories from the current category all the way back up to root. The function seems to work fine if I output directly from it using echo, but if I instead try to return the string to the global scope and then echo it, I get nothing. The line where I use echo/return is indicated below.
Thanks,
Andy
function breadcrumbs($category_id=0,$mode='linked'){
global $id_array,$name_array;
static $counter = 0;
if ($category_id == 0) {
//once we're down to the root, build a return string
if ($mode == 'linked') {
$output = '<A HREF="' . $_SERVER['PHP_SELF'] . '">HOME</A>';
} else {
$output = 'HOME';
}
while($counter > 0){
if ($mode == 'linked') {
$output .= ' > <A HREF="' . $_SERVER['PHP_SELF'] . '?category_id=' . array_pop($id_array) . '">' . array_pop($name_array) . '</A>';
} else {
$output .= ' > ' . array_pop($name_array);
}
$counter--;
}
return $output; /*<--------HERE: IF I SUBSTITUTE "ECHO" FOR "RETURN", EVERYTHING WORKS; BUT WITH "RETURN", IT DOESN'T WORK*/
} else {
$sql = 'SELECT category_id, parent_cat, category_name FROM web_categories WHERE category_id = ' . $category_id;
$result = safe_query($sql);
while($query_data = mysql_fetch_assoc($result)){
$id_array[$counter] = $query_data['category_id'];
$name_array[$counter] = $query_data['category_name'];
//now, move one step up and make the current category the previous parent
$category_id = $query_data['parent_cat'];
$counter++;
breadcrumbs($category_id,$mode);
}
}
}
$show = breadcrumbs(9);
echo $show;
attached mail follows:
I think it will work if you return true, and just modify the global variable (not try to output it).
Then output it (or capture it to begin with ($total_count = OneHundred();) after the function is called.
You could also pass the variable, rather than making it global (OneHundred("0") initially, and OneHundred($count) from within the function).
For instance:
<?php
function OneHundred(){ global $count;
if($count < 100){ $count++; OneHundred(); } return true; }
OneHundred();
echo $count;
?>
Hope that helps, Brian

Thanks very much, Brian. Your response helped me find the answer. On the recursive call to breadcrumbs(), the function wasn't actually returning anything to itself. I replaced "breadcrumbs()" with "return breadcrumbs()" and everything now works.

Hello,
I have the code below, but it doesn't work. I see the message "It is an array" but nothing else. What can be the problem? How can I get the actual browser language?
I use WinXp Prof, Apache 2.0.43, PHP 4.2.3, safe_mode is on.
Thanks!
<?php global $HTTP_ACCEPT_LANGUAGE; $arr_lang = preg_split('/(\s*,\s*)/', $HTTP_ACCEPT_LANGUAGE); if (is_array($arr_lang)) { echo "It is an array"; $lang_first = strtolower((trim(strval($arr_lang[0])))); echo $lang_first; $lang_first = substr($lang_first, 0, 2); $lang = $lang_first; echo $lang; } ?>
attached mail follows:
When I run, $r = get_browser(); and take a look at the css value, I get 2. I would have figured that it could only be 0 (not supported) or 1 (supported). What are the possible values for get_browser()'s css, and what do those values mean?
attached mail follows:
Okay, if I understand everything correctly, something like this may work, if you can get around the issue of your file sizes being so large, and you can deal with the amount of memory this is going to eat up, and you realize that Perl is probably better suited to the job...
//read numbers $numbers = file("in.txt");
//read all lines from log file $fp = fopen("file.log","r"); $log_file = fread($fp,filesize("file.log"));
//match lines of log_file that start with 'code' //and match number preg_match_all("/^(code.*number=([0-9]+).*)$/m",$log_file,$matches);
//put matches into an array such as // $array[code] = number $x=0; foreach($mathes[1] as $code) { $number = $matches[2][$x++]; $log_file_array[$code] = $number; }
//compute intersection of log file array //and numbers array $intersect = array_intersect($log_file_array,$numbers);
//flip the log array, so you now have //an array full of the lines in the log //file that matches a number in the in.txt file $answer = array_flip($intersect);
Hope that works... I can't test it. There are many ways you can do this...

That won't work, either. It'll write "Array" to your file, probably.
You'll want this:
$answer = array_flip($intersect); $results_file = implode("\n",$answer); fwrite($results,$results_file);

I had it figured out!! Don't need to decrypt it. Instead, I can encrypt the account number by javascript. Grab the unencrypted account number. Put it into two variable, encrypt the first one with PHP and match it by Javascript. If accept then I use the 2nd variable to grab the data from the data and put it into the sessions. This will take care of the problem with my other project....

Lemme guess? Was it going to be a revolutionary compression program that can compress any file to 128 bits?
In all seriousness, the output of MD5 is not encrypted, it is a digest. That, BTW, is what the D stands for.

nope, that's way it is called one-way function. But if you could, I assume it would be worth a big pile of money ;).

Hi,
I'm new to php (ok new, try 3 days ;), althought, I'm finding it fun, I 'm trying to think of a project to do, to get me more into it.
And after having a discussion with a friend and also setting up several Mailman mailing lists for people that want to compose HTML mails and post them as newsletters, it got me thinking, would I be able to create a similar program to mailman in php?
So admins just login to the list. copy and past the html into a text box and php then renders it for a preview, then if they like it, they click send, this send queries the database and sends it to all the people list to receive mail on that list.
I would assume that the sending could be handed off somehow to sendmail/postfix?
The list front end would also hold list preferances as well, for subscribers and admins, basically I want to mimik Mailman, but in php and be able to render previews of mails first, basically it will be a newsletter program, rather than a mailing list one, which is where Mailman falls over.
Cheers

Yes, but you are recommend to set sendmail with the appropriate queuing flags so it does not stall your PHP script while attempting to deliver to every subscribers and instead just queue the messages without delay.
In that case you may want to try this class for composing and sending messages, that has a sub-class for sending using sendmail program directly. It already comes with options that let you tell to just queue the messages without delay as needed.

Yes, but keep in mind that besides composing and sending messages, you also have to take care of creating subscriber records, validating subscriber addresses, handling bounces, handling unsubscriptions, etc... and dedicating mailing list manager programs already do that.

Yes, this is a reasonable candidate for a PHP project, however:
1. why reinvent the wheel?
2. There are some serious issues with using PHP's mail() command:
a) large mailing lists will time out on individual emails
b) the alternative to a is to use Bcc. Your ISP will probably set the maximum to 100 emails in a Bcc, which throws that idea out the window
c) the alternative to a and b seems to be injecting emails directly into the mail que with sendmail, and all sorts of stuff I haven't looked into yet.
There is a class (not not a tutorial, a class in OOP way) on phpclasses.org which offers (what seems to be) every answer to the above issues, but I've never used it, and it's OOP nature may be a complex way to get into PHP.
There are literally 100's of threads about mailing lists in the archives.

Does anyone happen to know why the below code reads the directory in reverse alphabetical order? Not a major problem - easy enough to whack it in an array and sort it, but annoying nonetheless.

is it on a unix system?
if so, do an ls on the system and you will see that the files are listed in that order.
it is the order in which they were copied to the directory.
try going through a loop before you run your main loop, create an array() then sort that with some sorting functions and you'll have it.

First of all, you don't need to type in all caps like that. I thought this was the Nigerian Scam for a minute there! :-) Anyway, in PHP 4.2+, the php.ini setting register_globals is off by default. You'll need to either turn it on, or start using the newer $_POST superglobal array. For more information, take a look at http://www.php.net/manual/en/security.registerglobals.php.

Hi,
I'm trying to construct a regular expression to find HTML open tags without closing tags up to another of the same HTML open tag or a closing tag of a different type that's no enclosed in the implied closing tag optional HTML tag (for example <p> doesn't require a closing tag. The closing tag is implied and so is its body).
For example, the HTML snippet:
<html><head><title>Test HTML</title></head> <body> <p><font>This tag is ok<br></font></p> <font><p>I want to find this p tag<br> and up to the next opening p tag<br> <b>test<br></b></font> <p>I want to find this one too </body>
I don't want to find <p> tags with a complete structure. ex: <p>This is a <p> tag with a complete structure</p>
Instead, I want to find the <p> tag with no closing tag, up to the next <p> tag or a closing tag of any type that doesn't have an opening tag after the initial <p> found (not including this orphaned closing tag)

Hi...
A simple question... In the following code:
<?
$ip = getenv("REMOTE_ADDR");
echo " ip = ".$ip;
echo " ip = " . getenv("REMOTE_ADDR");
echo " ip = " . getenv('REMOTE_ADDR');
echo " ip = ". $REMOTE_ADDR; <------
?>
I can only seem to get the last line to display the correct value. It's as if I can't seem to get/return any of the SERVER environment variables using the getenv() function....
I'm using Apache 2.0.40, PHP 4.2.2 on Linux RedHat 8.0.
I've checked through the PHP.INI file, but couldn't seem to find why this might be occuring. Any help/assistance would be appreciated.....
thanks

just copied your code and it worked fine for me.
system: Apache 1.3.26 PHP 4.2.2
I would look into apache 2.0 and the env vars that are available from it.

Do this:
<?php
print_r($_SERVER);
?>
If what you want is here this just use: $_SERVER['REMOTE_ADDR'] etc
You will need to have a look at the source of the output as the rendered view will look a little strange.

Anyone tried to use Jasper Reports with PHP? Jasper is a java reporting tool, but I need an os alternative to Crystal Reports and am hoping it might fit the bill.
I *think* I could integrate Jasper into my app fairly well with PHP's ability to call Java classes, but wanted to hear from anyone else with experience in this area.
Thanks, John

When someone logs in, save their ID somewhere. If they try to log in again, check where you save the names and see if it's there.
Checking my crystal ball, though, you're going to run into problems. What if I log in, accidentally close my window, and then go back to try and log in again. Odds are your "security" feature will not allow me to log in, because it thinks I already am.
Bottom line, why worry about it?

I think that's only problem I want to know cause I affraid that I can't hold the dead or alive of session
OK, I'll try to trace session by reading /tmp directory
thanks a lot

Well, not exactly. You see, this is a rather strange
restriction (or seems strange to me at least).
There are two different data stores in a typical session
management environment:
1. Session data store. This is all of those /tmp/sess*
files if you are using the default setup.
2. User (or client) data store. This is where you would
keep persistent data, such as username and password.
You could store a login indicator in the user data store,
so that when a user logs in, you make sure this flag is not
set (else deny their login) and set it if it is not. This
would work for a lot of cases, but it has a few notable
problems:
1. It is not atomic. Under heavy load, you can experience
synchronization problems where multiple clients check the
flag, see that it is not set, and all try to set it. This
is a rather unlikely prolem, but it is something to
consider.
2. How do you know that someone is logged in? For example,
if I login to your site (and you set my login flag to 1),
how much inactivity will you tolerate before you consider
me no longer logged in? Do you consider me logged in as
long as I have a session record? What if I accidentally
close my browser and go back to your site (and am not
recognized due to my cookie being lost). Will you not allow
me to log back in to your site until my login flag times
out?
I think this seems like a bad idea, but you might try this
idea to see if it works well enough for you.
Good luck.
Chris

I couldn't find "paht" on websters.com.
You'll need to send the appropriate headers to tell the browser you're sending an attachment and it should prompt the user to save the file.
This question is answered all the time, search the archives for the examples.

Hi
I've built a secure site. After the user has chosen a valid username and password I want my script to run htpasswd on the .htpasswd file in the directory. The script can run htpasswd as it doesn't have permission. What is the safest way to do this? Should I chmod htpasswd or is there a better option for this whole thing??
Thanks
Kris
attached mail follows:
Don't chmod .htpasswd- _huge_ security risk... Will your server allow you to have suid scripts??? If so, you can just write a little wrapper and make it suid. If you do that, I'd also reccomend using an extension other than PHP, and/or placing it outside your web root. Wouldn't want people adding themselves...
I'd reccomend not using .htaccess at all, and just whip up a system using a real database, wth the real work done in PHP. htaccess just isn't designed to be dynamic.

break ends a loop. That's what it does. If you don't want to end a loop, don't call break.
Take a look at your code; it boils down to this:
while (...) { break; continue; }
Generally speaking you would break or continue based on some condition. Your usage as shown below doesn't make any sense to me. Perhaps you need to re-read the documentation on while, break and continue.

You are misunderstanding how break and continue work. When you call break, the loop ends. When you call continue, the loop starts over, skipping the part between continue and the end of the loop.
When you call break, you're ending the loop. You never even get as far as continue (let alone as far as the second <TD> block).

I am having a problem with a post method.
GET method: _REQUEST['name']=value _GET['name']=value _POST['name']=
POST method: _REQUEST['name']=valuename=value _GET['name']= _POST['name']=valuename=value
I assumed that by using _REQUEST that I could use either a POST or GET method on the form. I can't, so does this seem right? The extra name=value seems like it shouldn't be there.

Everything after the question mark is a query string. Say you have this...

to access these values in your script...
$_GET['var1'] $_GET['var2'] $_GET['var3']
In other words, if I want to print out the value of var2 on the page....
echo ( "This is var2 : " . $_GET['var2'] );
Will print this out to the browser....
This is var2 : value2

I'm working on mass mailing list application and doing my research on the part with the actual delivery of the message. I've been using a Perl script called MojoMail which sends out blasts just fine and boasts that SMTP is the fastest way for delivery than with Sendmail using a module called BulkMail. I always understood that SMTP adds an additional layer around the MTA which really slows things down, however only useful if you plan to blast emails across several SMTP servers for a load balancing purposes.
So that's a 'pro' for using SMTP. The 'con' is that delivery is not quite as fast.
Then with PHP's mail(), folks have been saying that because it opens/closes a connection, looping through mail() adds additional overhead and that the best way would be to pipe into the MTA with popen()/pclose()
Now I'm curious which method is really better...Piping into the MTA will still open/close the connection and adds the same amount of overhead as mail() do right? What are your thoughts on SMTP?

People that say that are either Windows users or have no idea how mail works. Only on Windows the mail() function relays messages to a SMTP server. Under Unix/Linux mail just calls the sendmail program piping the message data to the standard input like with popen and pclose.

Forget relaying on a SMTP server even when it is the local server. Relaying via SMTP just does the same thing as piping data to sendmail except that it takes a longer trip by establishing a TCP connection to the SMTP server.
To make relaying faster, it is better to call sendmail directly passing the necessary switches to make it just accept the message without any delay so it will free your PHP script. Delivery will happen next time it will run the queue.

you will need to split the last bit and treat it as a number to increment it properly, something like
list($ip4,$ip3,$ip2,$ip1) = split('.',$ip1); list$ip8,$ip7,$ip6,$ip5) = split('.',$ip2); $ip = intval($ip1); $endip = intval($ip5); while($ip < $endip){ $storeip = $ip4.'.'.$ip3.'.'.$ip2.'.'.$ip; //store it $ip ++; } There are probably other ways but you get the idea

I can say with near certainty that there is a problem with the session handler you've chosen, for you to be getting these segfaults. As I pointed out, and as you've stated, if the sessions work fine with the 'files' handler type, then the issue must be with the alternate handler.
So, if you wrote it yourself, perhaps it's got a bug. If it's a library script, perhaps it has a bug, or has a FAQ, or some support.
There's also the option that there's a bug with PHP in this/these version(s) which is causing the problems.
Is there a reason why you can't just use 'files'???

I'm weighing down personalization and enveloping for this project, and probably going for the personalization of each email. This rules out BCC and enveloping with SMTP.

If it delivers when possible, won't the server flake if it get's 100,000 emails inject into Qmail? If I was to use your class and loop through 100,000 emails into Qmail, will Qmail attempt all at once?

Very interesting... I hadn't thought about that. Definately don't want legit emails mistaken as SPAM.

Right. . . however I was more curious on a comparison between piping into Qmail vs SMTP. So far, you have prooven greatly the differences and has swayed my decision alot :)

I'll check it out. We've been using Bind and are considering of using TinyDNS, but also heard good things about DJBDNS. Mainly we are looking for PostGreSQL extensions because we built a web hosting control panel that's rounded around PostGresSQL to manage services.

Thanks, I'll check QMQP as well.

We had a 72K list with about 6K bad emails that Mailman didn't unsubscribe until we used MojoMail which unsubscribes them from the database instantly as well as perform validations. Now, blasts are handled alot quicker.
So far, you have given me a good case to use Qmail and using your PHP class as a foundation for this application. . . I'll have to check the other software recommendations you made and see how'd I incorporate this into the application.
BTW, isn't there any overhead associating with opening/closing a connection to inject each email into Qmail? Or it's very minimal overhead to even worry about? If 100,000 was looped and injected into Qmail, is Qmail fast enough that 100,000 emails are not just sitting on the server filling up disk space?
attached mail follows:
Q If it delivers when possible, won't the server flake if it get's 100,000 emails inject into Qmail? If I was to use your class and loop through 100,000 emails into Qmail, will Qmail attempt all at once?
A The answer was right above the question... "With qmail you do not have to run the queue like sendmail. You just inject the messages and it will deliver them when possible." It will build up a queue of everything it needs to send, then send them one at a time (or ten, or a hundred- you can configure that...) until it's done. It will never DoS itself by trying to send 10K eMails at once. Think of the queue as a long line. Mail waits its turn, then gets attention when it reaches the front of the line.
Q BTW, isn't there any overhead associating with opening/closing a connection to inject each email into Qmail? Or it's very minimal overhead to even worry about? If 100,000 was looped and injected into Qmail, is Qmail fast enough that 100,000 emails are not just sitting on the server filling up disk space?
A It's more than worth the overhead to use qmail. Basically, qmail does all the hard work for you. First of all, it sends multiple messages at once (default is 20, but it's configurable), so you're connection is never idle waiting for that SYN|ACK, DNS query, SMTP acknowledgement, etc. Now theoretically _could_ do this with PHP (pcntl), but why re-invent the MTA? It probably wouldn't be nearly as efficient, and it would take an eternity to develope a script that even approaches qmail's functionality.
Now, with regards to a MLM (mailing list manager), you may want to take a look at ezmlm. You can find it (and qmail) at http://cr.yp.to/ It doesn't just delete addresses from the database automatically, but first sends a little probe eMail, threatening to delete the address if the probe bounces. It's a pretty cool feature, since it prevents good addresses from being dropped for stupid reasons. For instance, I get them sometimes (securityfocus runs ezmlm on bugtraq and vuln-dev, prolly their others too, and vulnwatch/vulndev both use it) when mail bounces due to MIME types that can be naughty (exe, vbs, com, eml, hehe .fon, .ttf, .otf soon?), or when someone uses profanity, or even if the DNS was temporarily down. Now personally i don't care about profanity or naughty MIME types, but lots of ISPs (like mine) filter them. Just something to think about.

Thank you! That's the kind of answer I was looking for.
If I understand correctly PHP will not work correctly because some parts of it are not thread-safe.
Is the PHP team working on getting PHP to be thread-safe? Does it look promising? Might version 5 be thread-safe?
Thanks again,

No, you didn't understand correctly. I specifically said the thread safety issues were in 3rd party libraries and not in PHP. This is not going to be solved anytime soon since it isn't really something we can fix. We can hack around it and add mutexes and stuff to protect ourselves from broken libraries, but in the end that just brings us closer to the non-threaded model that we already have with Apache-1.3, so there is very little motivation to even go through this bit of pain.
Why exactly are you asking? Is there some feature in Apache2 that you need that is not available in Apache-1.3?

Sorry, I thought by 3rd party libraries you meant libraries that PHP is dependent upon. Do you mean libraries used by PHP or Apache. And if these are libraries used by PHP, do you mean library that as in the multi-byte library (i.e. libraries that add functionality to PHP), or do you mean C libraries used when compiling PHP.

I don't want to move from Apache 1-3 to Apache. I just keep hearing that PHP is not ready for Apache2 yet and I wanted to educate myself as to why. I don't like just being told something and not understanding the reason behind the answer.
So this boils down to Apache2 using threads and PHP not being thread-safe?
And the reason that PHP is not thread-safe is that some 3rd party libraries PHP used are not thread-safe.
Now the only two questions I have left are : #1 what those libraries are used for. I.e. are they part of PHP or libraries that are used to compile PHP?
If they are libraries used to compile PHP, I would assume that Apache2 must have faced similar issues when going from a forking model to a threaded model?
#2 Is there progress being made towards having PHP work with Apache2. And who is working on this (if not the PHP team).
Thanks again for the clarifications!

Common libraries such as gdbm or c-client, for example.

Why? Apache by itself doesn't need to talk to anywhere near the same number of 3rd-party things that PHP commonly talks to.

Nobody really is. And I don't see this changing until there are some really compelling features in Apache2 to warrant the massive effort it would take. And yes, a working perchild mpm may be that compelling feature, but we don't have one of those.
All of this stuff is available by reading the PHP and Apache dev lists, by the way. They are archived and not that hard to find.
