WAMP 2.2 Localhost调用未定义的函数curl_init()

I am using wamp 2.2 with php 5.3.13 and Apache 2.2.22 and I am getting this error on my localhost:

Call to undefined function curl_init()

I removed ; from extension=php_curl.dll My extension_dir = "c:/wamp/bin/php/php5.3.13/ext/" is correct I have restarted my wamp server and even download the php_curl.dll from the following URL http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/

and I am still getting this error...anyone got any ideas?

Thanks, J

Make sure the php_curl extension is selected in your Wamp PHP extension options.

Edit to make the answer clear: There are two php_curl.dll files to be found on the website linked to in the question: http://www.mediafire.com/file/0hm40owj08y68p7/php_curl-5.3.13-nts-VC9-x64.zip and http://www.mediafire.com/file/qwgdzgccthzwc15/php_curl-5.3.13-VC9-x64.zip

Looks like only one of them worked for the OP.
