Description:
------------
I was trying to repro a crash I get when using fastcgi and any script more complex then hello world, and I came across this gem ...

I'm using IIS7 (tried both VistaSP1 and Win2008), with FastCGI and the attached script fails.  but if I shorten the name of the function, then it doesn't fail!!!  freaky.  

important note, it doesn't fail the first time, only the 2nd, so hit refresh a couple of times in your browser.  if I switch to CGI, then it works fine.

what difference could the name of an uncalled function have on php_mysql.dll?  mmm ...

Reproduce code:
---------------
differences versus php.ini-recommended
    extension_dir = "./ext"
    cgi.force_redirect = 0

index.php
    <html><body><?php
	function abcdefghijklmopqrstuv($s) { return $s; }
	if (!extension_loaded('mysql')) @dl('php_mysql.dll');
	if (!extension_loaded('mysql')) die('mysql not loaded');
	$dblink = mysql_connect('localhost','root','root');
    ?></body></html>


Expected result:
----------------
no error or warning

Actual result:
--------------
PHP Warning: mysql_connect() [function.mysql-connect]: Too many open links (0) in C:\hobby\test\index.php on line 7

NTS seems to fix it.  so is it just that TS is buggy? or that FastCGI is not compatible with TS?

Can you try a simple phpinfo with the TS version?

However, you should actually use the NTS version as long as you use fastcgi. dl is also not a good thing to use.

May I ask with OS and IIS version you use? out of curiosity :)

I can't as I also need Zend Optimizer which requires TS.  (note, zend is not installed during these tests).

mmm ... with many projects on one server, each requiring a different set of extensions, it seems wrong to load bucket loads of extensions for a trivial script that needs few/none.

it also eases install on different servers by making my app more independant of the php.ini/php-cgi-fcgi.ini which I feel should be reserved for not app specific settings.

from my orig post

>> I'm using IIS7 (tried both VistaSP1 and Win2008)

also, my vista box is x64, and the win2k8 is x86

"I can't as I also need Zend Optimizer which requires TS.  (note, zend is not installed during these tests)."

They have a NTS version. Also I would not use this extension with official php releases. But that's not the cause as it is not loaded :)

"mmm ... with many projects on one server, each requiring a different set of extensions, it seems wrong to load bucket loads of extensions for a trivial script that needs few/none."

You can create more fcgi instances, per application or script. With custom php.ini for each version.:
