PHP中的GD2库未安装

Question

I'm having problems installing the GD library. I'm using an IIS server with PHP 5.2.14. I uncommented extension=php_gd2.dll in php.ini.

This is the error:

gd: Unable to initialize module
Module compiled with module API =20060613
PHP compiled with modlule API = 20090626
These options need to match
  in Unknown on Line 0

I downloaded various PHP versions to try and get the correct DLL, including thread-safe 5.2.14. I would then restart my application pool and try to load a file that uses the GD library. Are there other files necessary for gd2 to work? Are there any quick ways to solve this without reinstalling PHP entirely?

Answer 1

first, iis7 was not configured properly for php - I searched for a guide that walked me through. Second the directory was incorrect, whenever I reset the iis server it originally would say one directory when ISAPI api was being used- but after 2 mins it would say extension_dir was in another directory when cgi/fastcgi is being used. So i created that directory that it wanted (which was different than any of my php.ini's). The one it was pulling from needed to be put in the C:/windows directory, but even though I had it set to go to "./ext" it wanted to go to Program files/PHP-- extremely weird. Third, I had to add IUSR to the permissions of any folder being used.
