The php curl component in php is not supported by default. The following editor will introduce to you a text tutorial on configuring the php_curl component under Windows 2003. I hope this method will be helpful to everyone.
A) Support php_curl component
1. Find php.ini (usually in c:/windows/php.ini) and modify extension=php_curl.dll to remove the preceding semicolon.
2. Check whether there is a php_curl.dll file under the php installation directory/ext directory.
3. Copy the two dlls, libeay32.dll/ssleay32.dll, under the PHP installation directory to windows/system32.
4. Restart the php service. Just restart iis.
5. If you have completed the above steps and it still doesn’t work, then click on the server: My Computer->Properties->Advanced->Environment Variables->System Variables->Path->Edit
Increase the variable value:
;D:/APMServ5.2.6/PHP;D:/APMServ5.2.6/PHP/ext
D:/APMSer5.2.6/PHP here should be replaced with your PHP installation directory.
