curl_exec -- Perform a CURL session


mixed curl_exec ( resource ch)

This function should be called after you initialize a CURL session and all the options for the session are set. Its purpose is simply to execute the predefined CURL session (given by the ch).

例子 1. Initializing a new CURL session and fetching a webpage

// create a new curl resource
$ch = curl_init();

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "");
curl_setopt($ch, CURLOPT_HEADER, 0);

// grab URL and pass it to the browser

// close curl resource, and free up system resources

注: If you want to have the result returned instead of it being printed to the browser directly, use the CURLOPT_RETURNTRANSFER option of curl_setopt().
