Activation Curl on EasyPHP
This as, Anar Hariyev states, works:
100% working solution, I won this problem!
1) Copy libssh2.dll from php directory to Windows/system directory
2) In php.ini #zend_extension remove (;) front row ;extension=php_curl.dll
3) Restart Apache server.
However, you can copy libssh2.dll into Apache's bin folder as opposed into the Windows System directory. This keeps the server portable.
