Call to undefined function curl_init() error in wamp 2.2
Visit this and have a file under Fixed curl extensions:http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/after download and replace related file then restart server.In browser navigate to localhost and make sure there is curl extensions showing under Loaded Extensions :
For WAMP running PHP 5.4.3 on Windows 7 64 bit, make sure you use php_curl-5.4.3-VC9-x64.zip NOT php_curl-5.4.3-nts-VC9-x64.zip.
In windows 7 with PHP 5.5.31 after check that php_curl.dll extension is enabled (and still doesnt working), work for me to copy libeay32.dll and libssh2.dll from php directory to Apache bin.
