curl_init

Initialize a CURL session (PHP 4 >= 4.0.2, PHP 5)
resource curl_init ( [string url] )

The curl_init() will initialize a new session and return a CURL handle for use with the curl_setopt(), curl_exec(), and curl_close() functions. If the optional url parameter is supplied then the CURLOPT_URL option will be set to the value of the parameter. You can manually set this using the curl_setopt() function.
