Using W32api functions in PHP

Hi, I am trying to use some W32api functions in PHP (to do some Windows NT Domain login stuff). Problems I am having: I have looked at: http://www.php.net/manual/en/ref.w32api.php Which gives a simple example of using dl() to load the appropriate dll extension, then registering the functions I want to use and running them. The first problem I run into is: Warning: dl() [function.dl]: Not supported in multithreaded Web servers - use extension statements in your php.ini in c:\program files\apache group\apache\htdocs\pm\login.php3 on line 39 So rather than use the dl() function, I used a line in my PHP.ini file: extension="php_w32api.dll" to load the extension as it says in the warning. However, this does not seem to load this extension at all, because when I call w32api_register_function, I get: Fatal error: Call to undefined function: w32api_register_function() in c:\program files\apache group\apache\htdocs\pm\login.php3 on line 44 And when I run: extension_loaded('php_w32api.dll') It returns false and running php.exe -m on the command line does not list php_w32api.dll loaded. However, if I change the line extension="php_w32api.dll" to extension="php_w32api1.dll" i.e. so that the dll does not exist - an error is listed in the log saying it cannot find the dll, so I figured it must be loading it cause it does not list an error on the line when the name is correct. Sorry for the Essay bordering on War and Peace. Hope someone can help me out? Cheers, Andrew
