Пример 1

For anyone trying to dynamically add links to mcurl and removing them as they complete (for example to keep a constant of 5 links downloading), I found that the following code works:

$mcurl = curl_multi_init();
for(;;) {
    curl_multi_select($mcurl);
    while(($mcRes = curl_multi_exec($mcurl, $mcActive)) == CURLM_CALL_MULTI_PERFORM);
    if($mcRes != CURLM_OK) break;
    while($done = curl_multi_info_read($mcurl)) {
        // code that parses, adds or removes links to mcurl
    }
    // here you should check if all the links are finished and break, or add new links to the loop
}
curl_multi_close($mcurl);

Пример 2

$running=null;
//execute the handles
do {
    while (CURLM_CALL_MULTI_PERFORM === curl_multi_exec($mh, $running));
    if (!$running) break;
    while (($res = curl_multi_select($mh)) === 0) {};
    if ($res === false) {
        echo "<h1>select error</h1>";
        break;
    }
} while (true);

Пример 3

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

// set URL and other appropriate options
curl_setopt($ch1, CURLOPT_URL, "http://www.google.com/");
curl_setopt($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);

$running=null;
//execute the handles
do {
    curl_multi_exec($mh,$running);
} while ($running > 0);
//close the handles
curl_multi_remove_handle($mh,$ch1);
curl_multi_remove_handle($mh,$ch1);
curl_multi_close($mh);
