i just wish people were smart enough to understand that no one cares
about the spam in the other persons mailbox. we only care about the spam
in our own. in this case people shouldn't use any spam filtering
techniques that adversely affect other people, or require interaction on
the part of the sender.
i think he'll ban himself considering it says you won't be given another
opportunity to return his confirmation email.

I think this is the best solution, it is very similar to how I implement
virtual hosting.

This is how I'd do it. And this way the includes directory would be completely outside both webroots, so no chance of them being served up by accident!

Careful, that will eat your array as well. When the while loop finishes
you won't have any pieces of pie left!
IE:
$applePie = array(1,2,3,4,5,6,7,8);
while ($pieceOfPie = array_shift($applePie)) {
echo $pieceOfPie; // want some pie?
}
// Both of these are now true:
$applePie == array();
$applePie != array(1,2,3,4,5,6,7,8);

that was the idea: you can't have your pie at eat it right? ;-)
seriously thought, John Taylor-Johnston was asking for help on while
loops and I thought I'd give him some brainfood (i.e. a little
optimalization thrown in). besides which how many times have we in our PHP
careers not created arrays just to loop over them once, outputting each
item?

Oh yeah, that's one side effect of PHP, you completely forget about:
memory and garbage collection concerns.

attached mail follows:
I ran a test on the same machine for php4(port 80) vs. php5(port 8080).
Using the exact same code, I created 50 objects. It took twice as long in php5 as it did in the older php4.
I then ran a test to access a property of the class using a method of the class. Again, php5 was almost exactly twice as slow as php4.
Is it possible that php5 (I'm using the latest beta) is somehow compiled with extra debugging code or something like that? I was under the impression that php5 was going to better handle objects. Does this mean that it might be "better" but also slower? My biggest problem right now with PHP5 is that creating and using objects is pretty darn slow.
I'm a tad discouraged with these results.
Is there anything in the php.ini file that might be "tunable" for performance considerations?
Any help would be appreciated.
Thanks,
Dick

>From what I remember the speed improvement with objects in PHP 5 was
that they would be passed by reference, which I understand to be the
case. Try passing an object to a function, modifying it, then returning
it and echoing the result. I was surprised however to hear that you
found PHP 5 to be slower, I would be interested in any benchmarking
results you have. I also decided to do a quick test.
I wanted to test some decent sized classes so I used some I have written
already. Each class inherits from the one above it (names have been
changed to protect the innocent), therefore Class is a sub-class of
ClassData, etc. up to Object. Here is the wc output for the class
files:
43 200 1355 Object.php
190 533 5311 ClassBase.php
428 1554 15648 ClassData.php
481 1274 18831 Class.php
1142 3561 41145 total
Here is the script I tested with:
<?php
include_once('Object.php');
include_once('ClassBase.php');
include_once('ClassData.php');
include_once('Class.php');
function getmicrotime() {
list($usec, $sec) = explode(' ', microtime());
return ((float)$usec + (float)$sec);
}
$script_start = getmicrotime();
for ($x = 0; $x < 100000; $x++)
$a = new Class();
echo 'Script Time: ' . sprintf('%.4f',(getmicrotime() - $script_start))
. "\n";
?>
I tried to measure only the execution time of creating 100,000 objects
as accurately as possible. Creating them in an array would have been
interesting as well, but rather memory intensive, so I decided against
it. Another note is that I did run PHP 5 in cli mode only. I installed
both copies of php as well as apache2 and Turck MM Cache through emerge
on a Gentoo system. They were compiled from source but I did not change
their optimizations from the default. Since this is a testing box PHP
is installed with pretty much everything. Disclaimers aside, below is
what I found.
PHP 4.3.4 and apache2:
Script Time: 16.0964
Script Time: 16.0322
Script Time: 16.0289
Script Time: 16.0710
Script Time: 16.0306
Average: 16.0518
PHP 4.3.4 and apache2 with Turck MMCache v2.4.6:
Script Time: 15.1848
Script Time: 15.2146
Script Time: 15.2527
Script Time: 15.2354
Script Time: 15.2507
Average: 15.2276
PHP 5.0.0RC1-dev (cli):
Script Time: 15.2346
Script Time: 15.2254
Script Time: 15.2538
Script Time: 15.2414
Script Time: 15.2554
Average: 15.2421
PHP 4 is a bit slower than PHP 5, however with an optimizer it comes to
be about the same, maybe a touch faster. If/when a PHP 5 optimizer
comes out this may change some. I hope to run more benchmarks as I have
time. Also, PHP 5 is still in Beta, and this is not even the latest
version.

Adam

Do you have a way to capture the raw HTTP? I'd like to see:
1. The HTTP Request
2. The output of print_r($_POST)
3. What Web server you're using (and version)
With this, I feel certain that we can figure something out.

This is a javascript question not a PHP question, but how about:
selectedAudits = 0;
if (myMultiSelect.length) {
for(i = 0; i < myMultiSelect.length; i++)
if (myMultiSelect[i].checked) selectedAudits++;
} else {
if (myMultiSelect.checked) selectedAudits++;
}

Correct. If there is only a single element with a name, JavaScript creates a single scalar checkbox property with that name; if there are multiple elements with the same name, it creates an array of those elements as that property. The existence of the '[]' in the element name has no significance for JavaScript -- it goes solely on how many of the elements there are.
Checking whether the .length property exists is one way of telling whether you have a single element or multiple ones!
Cheers!

Set it via php.ini. Usually php knows the temp directory the OS is using, so
only set this if you need something other than the OS's temp directory...

hi!
after having trawled through many google articles, i've been told that the best
way to redirect a person is using header("Location:url");
the problem is, i have form that is posted to another php script. This script then
processes the form and then writes up a html page and includes in that page any
warnings etc.
i want the user to have say 5s to read that page and then be redirected to
another page.
so i have something like
//process form
//write page
sleep(10);
header("Location:blah.php");
the problem is i get an error when the script gets to the header part, the error
being

You cannot send headers after you have sent content to the browser.

--> the best way to solve your problem is by using output buffering.
try to start with ob_start(); and at the end of your script call with
ob_end_flush() ;

The amount of memory or the amount of disk space???

Both for that matter. I have root access. I want to echo how much /var/xxx contains, and while I'm at it, how much my partition contains and how much is used.

Esacping is bad practis. Doing it, is to ask for trouble when you
try to port the code to another system that a) escapes in another

Subject: [PHP-WIN] Re: [PHP] Replace of ' in a query
Look at the addslashes command. You should always escape the values you
are accepting from user input. If you read almost any article on web
site security, it will mention something called SQL injection among
other things. This is a way to compromise your data.
For instance, what if a user entered:
"1" OR "A"="A"
Now what if you used that user input to filter a query. You may end up
with:
SELECT * FROM db WHERE field="1" OR "A"="A"
Which would return every record in the database.

$result=mssql_query($query,$numero);

If i cut and paste this to freetds i get a result of
5120. Can anyone spot why i am getting a zero with
php? There are no problems with any of my other
queries in my scripts.

Hi,
As far as I can make up of all the sites the Zend project is a php
script compiler... right?
If I got that one right, the next thing I noticed was that the examples
for the Zend engine are normal programs. My problem is that I've
developed a webbased program but I don't want to distribute the
source-code. Which is kinda a problem because otherwise I won't be able
to share it :)
So can the Zend engine run normal php scripts for webpages too?
And while I'm at it, does it make a difference in performance?
Last question, as far as I can tell its possible to buy the Zend
compiler and optimizer. Is there another way to compile php code into
something like the Zend code?
Cheers,
Berend Dekens

Hey everyone. I'm looking for assistance/suggestions/answers on how to
build a select dropdown box from data that needs to be pulled recursively
from a MySQL database. Basically the situation is mainly for a dicussion
thread system type of thing where I have categories nested inside
categories, nested inside categories... Anyway, I want to be able to build
a drop down box containing all the categories indented underneath it's
parent category to look something similar to this:
-------------------------
Top Level Category
- Nested Category
- Lower level
- Etc....
Top Level Category
- Nested Category
Top Level Category
-------------------------
Then the user will be able to select one from the dropdown menu. I have all
the categories stored in a MySQL database called site_categories. The table
is setup like this:
__________________________________
| Cat_ID | Cat_Parent | Cat_Name |

| 1 | 0 | Top Level 1 |

| 2 | 1 | Nested 1 |

| 4 | 2 | Nested 2 |
|---------------------------------------------|
Sorry for the bad pictures you hopefully you get the idea. Anything with a
0 Cat_Parent is a Top Level category. Then the others are all nested inside
other categories that have the same Cat_ID as the nested categories
Cat_Parent. I basically need help creating a properly indented dropdown
menu box using this structure from the database. I assume I'm gonna have to
use some sort of recursion here, but I'm not sure how to go about this.
Please help if you can.

Hi list,
I'm working on a not-so-big website (currently about 1,5MB without
database files) that will receive not-too-much traffic (let's say 1000
visitors a day, being optimistic here). It's supposed to be available in
Dutch and in English. I want one version of the scripts/pages, loading
language-specific content depending on the language setting in a cookie.
Now, I see two ways:
* store all content in a MySQL table, for the different languages
* use the include file approach
The question: how about performance? The include file seems the most
attractive at first sight, querying a database on each page request
sounds intensive. Then again, as the site grows bigger, language files
will grow and HTML output might not be too fast anymore.
Has anyone got experience with both approaches, and how they scale?
Thanks in advance,
Wald

Please explain exactly what the problem is. If you had a firewall in the way
and a normal FTP client couldn't login then whatever you do in PHP would not

Surely is a problem with the encoding... try ISO-8859-1
Ù = %D9
ë = %EB
ý = %FD
Ñ = %D1
à = %C3
At least it works for the URL while passing parameters thru GET

Well, I just cut'n'pasted the above and tested it and it works fine for me. The only things I can think of are fairly obvious ones that I'm sure you've already thought of:
* the postcode needs to be in upper case to match that regex -- if you want to accept lower-case input, it should be upper-cased before matching.
* have you tried echoing $_POST['postcode'] to make sure it contains what you think it should?
Also, I need to correct a minor error in the regexp; it should have read:
"/[A-Z]{1,2}[0-9][0-9A-Z]? [0-9][ABD-HJLNP-UW-Z]{2}/"
Also also, two other points points made in other solutions: you should probably add allowance for leading/trailing spaces, and for additional whitespace between the two parts of the code; and, as currently written, that regexp matches if there is a valid postcode anywhere in the input, so it should be anchored to the beginning and end of the string. Both of these can be catered for in the regexp (rather than with extra PHP code), resulting in:
"/^\\s*[A-Z]{1,2}[0-9][0-9A-Z]?\\s+[0-9][ABD-HJLNP-UW-Z]{2}\\s*$/"
