Everytime I try to load any dynamic library from the php.ini's extension_dir, I get the following error (the dll specified changes depending on what library I am trying to load):

Unable to load dynamic library 'C:\Inetpub\php\extensions/php_gtk.dll' - The specified procedure could not be found.

My php.ini file contains the following line:

extension_dir = C:\Inetpub\php\extensions

It occured to me that I was missing a trailing backslash; therefore I changed my ini file to:

extension_dir = C:\Inetpub\php\extensions\

This didn't seem to help as I got a similar error message:

Unable to load dynamic library 'C:\Inetpub\php\extensions\php_gtk.dll' - The specified procedure could not be found.

I then thought that maybe any dll I load from the extension dir must also be in the %systemroot%\system32 dir, so I copied the php_gtk.dll to C:\WINNT\system32.  Sadly, I kept getting the same error.

I also tried putting single qoutes and double qoutes around the extension_dir path... as you can guess, I got the same error.

This seems to me, to be a very serious problem!  I can't understand how the inability to load dynamic libraries has gone unnoticed for so many versions.

Any help on this matter would be greatly appreciated!

I am running php 4.0.4pl1 as a CGI on Windows 2000 / IIS.

As a side not, I have compiled and configured php many times, on various Linux installations, and dynamic loading works perfectly.
