Fatal error: Call to undefined function curl_init() (no replies)

Hi,

I am getting the Following error when I am calling curl_init function using a web api in wamp.

I have tried following

- Changed the php.ini (Removed ; from the code).
- Restarted Wamp after doing so.

Still getting the following error

"Fatal error: Call to undefined function curl_init()"

Please advise.
