Przykłady

Przykład #1 curl_multi_init() example

This example will create two cURL handles, add them to a multi handle, and then run them in parallel.


<?php
// create both cURL resources
$ch1 = curl_init();
$ch2 = curl_init();

// set URL and other appropriate options
curl_setopt($ch1, CURLOPT_URL, "http://lxr.php.net/");
curl_setopt($ch1, CURLOPT_HEADER, 0);
curl_setopt($ch2, CURLOPT_URL, "http://www.php.net/");
curl_setopt($ch2, CURLOPT_HEADER, 0);

//create the multiple cURL handle
$mh = curl_multi_init();

//add the two handles
curl_multi_add_handle($mh,$ch1);
curl_multi_add_handle($mh,$ch2);

$active = null;
//execute the handles
do {
    $mrc = curl_multi_exec($mh, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);

while ($active && $mrc == CURLM_OK) {
    if (curl_multi_select($mh) != -1) {
        do {
            $mrc = curl_multi_exec($mh, $active);
        } while ($mrc == CURLM_CALL_MULTI_PERFORM);
    }
}

//close the handles
curl_multi_remove_handle($mh, $ch1);
curl_multi_remove_handle($mh, $ch2);
curl_multi_close($mh);

?>

Simulate multiple threads request:


<?php


function multiple_threads_request($nodes){


        $mh = curl_multi_init();


        $curl_array = array();


        foreach($nodes as $i => $url)


        {


            $curl_array[$i] = curl_init($url);


            curl_setopt($curl_array[$i], CURLOPT_RETURNTRANSFER, true);


            curl_multi_add_handle($mh, $curl_array[$i]);


        }


        $running = NULL;


        do {


            usleep(10000);


            curl_multi_exec($mh,$running);


        } while($running > 0);


        


        $res = array();


        foreach($nodes as $i => $url)


        {


            $res[$url] = curl_multi_getcontent($curl_array[$i]);


        }


        


        foreach($nodes as $i => $url){


            curl_multi_remove_handle($mh, $curl_array[$i]);


        }


        curl_multi_close($mh);        


        return $res;


}


print_r(muti_thread_request(array(


    'http://www.example.com',


    'http://www.example.net',


)));


?>

If you fire off 10 curl requests in parallel you don't have to wait for all of them to be finished before accessing one which is already finished.
