When running PHP under IIS as an ISAPI module I am unable to load/use the php_pdf.dll extension.  This has been replicated on two seperate servers.  When doing a phpinfo() the PDF section does not display.  When running a script the error is "Fatal error: Call to undefined function: pdf_new() in ...".  Other extensions such as php_mssql.dll load just fine in this mode.

When changing the IIS configuration to run PHP as a CGI the php_pdf.dll extension then loads (is shown in phpinfo())and scripts run normally.

The copy of PHP 4.3.1 is the zipped binary from the php.net web site.  All the dlls are fresh and a new install a php was tested on the test server.  PHP is installed in C:\PHP.  The servers are running Windows 2000 SP2 with current hotfixes, IIS and MSSQL 2000 SP3.  The only other additional extension loaded is php_mssql.dll.

Set the "extension_dir" to have full path to the extension directory.

"extension_dir" is (and was already) set to the full path of the the extension directory.

; Directory in which the loadable extensions (modules) reside.
extension_dir = "c:\php\extensions"

Even if it was not, why would this work as CGI and not as ISAPI?

Let me guess: your php.ini is in c:\php?
 [2003-03-18 08:42 UTC] jwhittenburg at iss dot net 
PHP.INI is in C:\WINNT, there is no PHP.INI in C:\PHP.
 [2003-03-18 08:53 UTC] edink@php.net 
What is the location of php.ini printed under:

Configuration File (php.ini) Path

in the phpinfo() output?
 [2003-03-18 08:54 UTC] edink@php.net 
Also does extension_dir in phpinfo print correct value?
 [2003-03-18 09:23 UTC] jwhittenburg at iss dot net 
From phpinfo()

Configuration File (php.ini) Path C:\WINNT\php.ini
extension_dir c:\php\extensions c:\php\extensions

I have just checked in the exact same setup you have and pdf support shows up just fine in phpinfo under iis. This is not a php bug but most likely a local configuration problem. My only advice at this point is to re-check you configuration, make sure you're using correct php.ini file and that extension_dir= and extension=php_pdf.dll lines are correct.
