How do I go about installing PHP cURL on IIS? I have copied the php_curl.dll file into the PHP extensions folder, what else do I need to do?



You have to register the modul in the php.ini.

Look for:


And check for correct extension dir:

extension_dir = "c:/path to php/ext"
  • I've added extension=php_curl.dll to php.ini, and checked the directory is correct, but i'm still having no luck. Should cURL then appear on a phpinfo() once i've done those steps? – Probocop May 12 '10 at 15:07
  • yes it does appear. You have to restart the web server processes (depending on gateway cgi/fastcgi/iis-extension). – Bernd Ott May 31 '10 at 12:29
