curl_exec

(PHP 4 >= 4.0.2, PHP 5)

curl_exec -- Perform a CURL session

Description

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

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

// set URL and other appropriate options
curl_setopt ( $ch , CURLOPT_URL , "http://www.example.com/" );
curl_setopt ( $ch , CURLOPT_HEADER , 0 );

// grab URL and pass it to the browser
curl_exec ( $ch );

// close curl resource, and free up system resources
curl_close ( $ch );
?>

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() .
