To enable cURL in PHP I uncomment this line
extension=php_curl.dll
But cURL did not load on restarting Apache. Even on restarting the mach
Try this out:
Download the copy of the win32 PHP (not the installer one) from php.net (whichever php version that you want running on your webserver).
Then from the dll folder, copy these two files: libeay32.dll and ssleay32.dll to your Windows/System32 (whichever Windows you have).
And then from the extensions folder: get your php_curl.dll and place it under your /php/extensions folder.
Check your php.ini to ensure it's referring to the correct extension folder, for example:
extension_dir = "./extensions/"
And uncomment your extension to php_curl.dll for example:
extension=php_curl.dll
Restart Apache
Thanks. Hope it works for you.
For others who didn't get php 7.1 to load with any of these answers, see Enable cURL on PHP7 windows10 64 bit Apache 2.4
I upgraded to PHP 5.6.4 and curl stopped working. php.ini and ext were fine.
I solved this problem by adding C:\php (my php folder) to system variable Path in the Control Panel->System-Advanced->Environment Variables.
