Hi Everyone,
In the past I have setup many Mac OS X web servers successfully. Now
I'm trying to setup another OS X web server, but PHP will not work.
I'm having massive problems getting PHP to "make", and I'm all out of
ideas. After I configure PHP (./configure), and try to make it, I get
these errors:
make[1]: *** [php] Error 1
make: *** [all-recursive] Error 1
I've tried an alternative way of installing from Marc Liyanage's web
site, http://www.entropy.ch/ which was very easy to follow, but it
absolutely will not allow me to view any PHP pages through Apache.
PHP prints out the following error instead:
Warning: Failed opening '/Library/WebServer/Documents/test.php' for
inclusion (include_path='.:/usr/local/lib/php') in Unknown on line 0
As you can see, the file's name is test.php, but you should know it
has absolutely NO PHP code in it. It's contents are:
<html>
<body>
Why don't I work?
</body>
</html>
Anyone have any ideas?
If anyone is willing, could they download the latest source of PHP
and try to configure and make it (don't bother make install-ing
it...) If you have any success with it, let me know.
Thanks in advance!

Compile PHP and Apache with the bare minimum only, no fancy stuff. Try it then.

Instead of using print or echo to display the HTML table, just assign it all to a variable. Then you can print it out later, or mail it, or whatever.
Or use output buffering...

Do as much of the sorting/searching in SQL as you can. MUCH faster.
Use the mail class from http://phpclasses.org to do the html-enhanced email.
WARNING: Many readers will simply *TRASH* your "enhanced" email. Re-think your priorities.
Collecting your HTML in a variable is easy:
<?php $html = ''; # Get db stuff $html .= "<TABLE>\n"; # Loop through results{ $html .= "<TR><TD>$x</TD><TD>$y</TD><TD>$z</TD></TR>\n"; } $html .= "</TABLE>\n"; ?>
It's just like doing everything with "echo", only not. :-)
You may want to echo some stuff out as well, so you know what's happening...

Is their a function that returns an equivalent of $PHP_SELF?
attached mail follows:
You have many options. Do a call to phpinfo() and note all the predefined variables, such as PHP_SELF. There is also the __FILE__ constant, print that too.
Why do you request a function? If it's because $PHP_SELF is not set, that's because the PHP directive register_globals = off. Go through the predefined server array instead, it's sexier:
print $_SERVER['PHP_SELF'];

Hi,
I'm having some difficulties setting the include path for two of my sites. I had this working previously on a PHP3 server with the command in the .htaccess file:
php3_include_path ".:/path/to/account/root/"
However, I seem to be unable to set the include path with two new sites - one running PHP 4.1.2, the other using PHP 4.2.0.
I've gone through the settings listed on the PHP Configuration page: http://www.php.net/manual/en/configuration.php
Yet none seem to work.
php_value include_path ".:/path/to/account/root" php_include_path ".:/path/to/account/root/" php4_include_path ".:/path/to/account/root/"
Could someone please shed some light on this subject? I'm in a sort of bind as my client desperately needs their site up for a week long sporting event that just began this past Friday (yesterday).
Thanks in advance -Tim

This one _should_ work. Try it without the double-quotes.

I am using this basic example (from the manual iirc) for uploading files
<form enctype="multipart/form-data" action="upload.php" method="post"> <input type="hidden" name="MAX_FILE_SIZE" value="1000" /> Upload this file: <input name="userfile" type="file" /> <input type="submit" value="Send File" /> </form>
What I am trying to do then is to remove any spaces or punctuation that might be in the filename.
This is what I am using for the filename:
$FILENAME = $_FILES['userfile']['name'];
and this is what I was trying to use to remove the space and punctuation (all one line, might wrap in email):
$SAFEFILENAME = ereg_replace ("[[:punct:]]+[[:blank:]]+", "", $FILENAME);
But that does not seem to be working, and I have not been able to figure out why.
Any help appreciated.
Thanks

What the above seems to be doing is replace:
a series of one or more punctuation marks FOLLOWED BY a series of one or more spaces
Which is not what you want. Presumably anything which isn't alphanumeric is classed as either space or punctuation? If so:
I prefer preg_replace so try:
$SAFEFILENAME = preg_replace('/[^a-zA-Z0-9]/', '', $FILENAME);

It's better to specifically *ALLOW* certain characters than to try to list all the ones you do *NOT* allow:
# Get rid of gnarly characters in filenames: $filename = ereg_replace('[^a-zA-Z0-9_\\.-]', '', $photo_name); $filename = $filename ? $filename : chr(rand(ord('A'),ord('Z'))) . chr(rand(ord('A'),ord('Z'))) . chr(rand(ord('A'),ord('Z'))) . chr(rand(ord('A'),ord('Z'))); if (!ereg('[a-zA-Z0-9_-]+[\\.]*[a-zA-Z0-9_-]*', $filename)){ $filename = chr(rand(ord('A'),ord('Z'))) . chr(rand(ord('A'),ord('Z'))) . chr(rand(ord('A'),ord('Z'))) . chr(rand(ord('A'),ord('Z'))) . $filename; }
Here, I throw out anything that's not alphanumeric, underscore (_), dot (\\.), or dash (-)
I also accept that fact that some goofball will end up have a file name with *NOTHING* useful in it, and then I just make a random filename up.
Damned if I know why I felt the need for that last if(){} part...
Maybe ord('Z') should be ord('Y') and I was getting whatever comes after Z some of the time???
Or perhaps that just adds four more characters on when I *DO* need to make up random names?
That part looks pretty broken to me right now, but maybe I just need some sleep.

He may also consider the position of the inc/decrementor. Example (note that the first element of an array has index 0):
$a = Array(1,2,3,4,5); $i = 1;
executing
echo $a[++$i] will output 3 2
echo $a[$i++] will output 2 2
In both cases $i gets incremented, but the value used to access the array might be before or after the increment takes place, according to the incrementor (or decrementor, if you use --) position. A subtle, but often very handy nuance.

Sure! For starters, ANYONE could turn off cookies at ANY TIME, perhaps by accident, perhaps out of fear, perhaps out of ignorance, perhaps because they're on a shared computer, etc etc.
But to answer your question, every version of IE I've ever loaded onto my Mac (currently 5.1) has had cookies on by default.
To really answer your question, you need to:
a) not rely on cookies -- pass the session ID around in the url
b) look at compiling PHP with enable_trans_sid, which does this for you
c) test for cookies, and explain to those without that your site requires them, explain how to access them/turn them on, and perhaps provide a small subset of content or alternatives for those who won't/can't use them.

I'm interested in coding something in PHP which uses the TOC protocol to connect to AOL Instant Messenger (AIM). Has there been anything done like this in PHP?

The files are going to get deleted unless you do something in the upload script to save/store/copy them.
There is no problem. :-)
If, after you have created/moved them, you can't delete them, then you need to have done stuff like:
http://php.net/umask http://php.net/chmod
and have the correct settings on the source/destination directory permissions to get the files in the state that you want them in -- Whether that's deleting via a cron job, or manually or letting PHP do it.
Be warned that if PHP can delete them, so can anybody else on the shared server who wants to write a PHP script to delete them, unless you've configured PHP specially to run as a specific user, which is unlikely for most ISP setups.

What error messages are in Apache log? Do you get a core dump? Have you read the instructions on http://bugs.php.net/ ? Is the apxs you pointed out to PHP the current one matching your Apache installation? What was your configure line for Apache?

As far as I know, php_info() has never been a documented function. The manual has always re-directed requests for php_info to phpinfo. Try it yourself:
This is not a "new" behaviour nor a change in the language -- It's people using an undocumented alias that they shouldn't.
I do not understand why people insist on using undocumented features, much less putting them into text books.
Don't do that.
PHP actually has a pretty good history as far as backwards compatibility goes. Not perfect, perhaps, but pretty good.
I suggest you complain to the Author, Technical Editor, or Publisher of the book.
If that doesn't suit, feel free to write your web-pages in Fortran 77 :-)

I've heard that the DOM is a memory hog...
Are you using DOM or the other one, or ???
It's also quite possible that somewhere deep into the XML somebody line-wrapped an element, which is prefectly valid, but that isn't anticipated by your algorithm for reading/parsing the file...
That's the most likely source of the problem as described.

The things is...
If these are all done by header("Location: ...") then you are needlessly chewing up an awful lot of HTTP connections.
HTTP connections are, I think, a very limited and over-strained resource on a busy site.
Now, the price *might* be "worth it" for maintainability...
OTOH -- I suspect you could simply include 'processing.inc' in Interface B and have code that's just as maintainable without chewing up two/three/four times as many HTTP connections/processes.
You can't scale up when you waste HTTP connections.
As far as atomicity (not letting the user abort) goes, I suspect that is really better handled by transactions or, in a very crude way, register_shutdown_function to check that all the results "tie out".
Actually, modular design and clear interface/API/back-end design often obviate most of what beginners think they need transactions for, and a couple well-placed (and well-thought-out) flags/time-outs can get rid of the rest, until you actually get to the canonical "checkbook" (or any money) example... You can do those the hard way, but it's usually not as good a solution as a real transaction.
This is just my opinion, though, and I've often seen paradigms under fire for all the wrong reasons. "It won't scale up" is meaningless for a botique/niche site that won't every *NEED* to scale up. And yet you often see a Manager insisting on doing it "that way", while wasting a zillion people-hours on lame features and poor design layout and...
Ah well. Enough on that topic. I quit looking for a day job so I wouldn't have to worry about that kind of junk any more. :-)

Pretty much, take those and a little discipline with your programming staff, and you're done...
Maybe write some kind of error message system that creates a unique ID for each error message.
You can wrap it up in some Objects if that makes you happy.

>Is it possible to write to exif-headers in pictures?
I don't think any PHP built-in function will do that.
Your options include:
1. Looking at the PHP source and extending it to do what you want. (and contributing that back).
2. Using some external program to do it: http://php.net/exec
3. Digging into the guts of whomever defined EXIF (MPEG folks?) and writing some PHP functions that read/write exif data without screwing up the images.
I suspect none of these are terribly difficult -- It's just that nobody else has wanted them badly enough yet to do the work...

You may want to look at http://sourceforge.net for some interesting ideas of projects that are under-staffed, or at http://linuxfund.org (ditto).
If there's any particular "extra-curricular" activity you are interested in, do some thinking on what kinds of software might be particularly useful for that.

Try using the TrueColor functions.
I suspect that while it's possible for the JPEG to have a zillion colors, the actualy pallette in use for any particular image is limited.
Once you hit that limit, it gets ugly fast.
Before the True Color stuff came along, I wrote some really gnarly code that would essentially search out the least-used color, de-allocate that one -- which automatically re-mapped that color to the nearest, I think, and then I was able to allocate my new color flawlessly.
You really don't want to use this code, since scanning the whole image for all the colors and building up the frequency table is extremely inefficient, and almost-for-sure the True Color stuff will take care of you.

Any old select will return a result set that works with a query...
But if you need your PostgreSQL FUNCTION to return a result set, I *think* you need to use:
'set of XXX'
for the 'rettype' (return type)
and I *THINK* you can figure out what to use for XXX if you start digging to find the name/oid of the "complex type" that represents a row in your table here:
http://www.postgresql.org/idocs/index.php?catalog-pg-type.html
I've never done this, I just did a little digging right now, and this is where I would keep digging if I was working on this...
But it sounds to me like PostgreSQL already *has* a "complex type" to represent the tuples in your table, and you just need to find out what the name of that "complex type" might be. It may even turn out to be just the table name or something...

Depends who does the wishing :-)
The first time I compiled PHP, I tried to throw in almost everything that sounded remotely interesting.
That was incredibly time-consuming and frustrating.
I didn't even really understand what half that crap was, and then I had to go download and install and configure it and kick the tires on each one, and...
By the time I got so frustrated with it all, there was *ALREADY* a new version of PHP out. (It's not like I didn't have other stuff to do...)
So when I started over with that version I only compiled in the stuff I *KNEW* I would have time to mess with in the next six months.
HIGHLY RECOMMENDED ------------------ It don't matter what you choose, but choose only the stuff you're gonna need FOR SURE in the next six months. ------------------
If it turns out you were wrong, it's no big deal to download/compile/install one more toy, after you've been playing awhile.
Oh yeah -- Be sure to compile it as a CGI as well. You'll need that for cron jobs sooner than you think, and it's way easier when you still have the shell with the up arrow :-)
Actually, I always put my configure line in a chmod 700 shell script so I can just use it again.
I know PHP writes one out, but it's got all those quotes and stuff, and I like one I can just read.

This works fine, but is there a way to get apache to do it for me instead? Like, this for example...
<Location /server-info> SetHandler server-info Order deny,allow Deny from all Allow from 192.168.0.0 </Location>
Is it possible to have apache do this for a Vhost? like this...

Hi all,
I'm looking at some pretty complex regexp's at the moment for parsing HTML, stripping out some attributes, getting the values of others, etc etc.
The simple fact is that all these...
<A HREF=foo.php> <A HREF='foo.php'> <A HREF="foo.php"> <A HREF='foo.php' TARGET="something"> <A HREF=foo.php TARGET=something> <A HREF = "foo.php"> <A HREF = 'foo.php'>
... and many more are *valid* HTML mark-up. It starts to make the task look rather daunting -- especially if I want to get it right, rather than taking shortcuts.
I'm pretty sure I need to start looking at a state engine or HTML parser which can identify a tag, and seek out all the attributes of it, according to strictly valid HTML (preferably 4.01 strict), rather than working with regexp's.
As it turns out, I'm only looking to work with <A> at this stage, so I don't think it'll be a massive state engine, but I'd like to explore any other options or existing libraries of code before considering such a beast.
Any links / articles / code / whatever warmly welcome :)
