<?php

$urls = array(
"http://www.cnn.com/",
"http://www.bbc.co.uk/",
"http://www.yahoo.com/"
);

$mh = curl_multi_init();

foreach ($urls as $i => $url) {
$conn[$i] = curl_init($url);
curl_setopt($conn[$i], CURLOPT_RETURNTRANSFER, 1);
curl_multi_add_handle($mh, $conn[$i]);
}

do {
$status = curl_multi_exec($mh, $active);
$info = curl_multi_info_read($mh);
if (false !== $info) {
var_dump($info);
}
} while ($status === CURLM_CALL_MULTI_PERFORM || $active);

foreach ($urls as $i => $url) {
$res[$i] = curl_multi_getcontent($conn[$i]);
curl_close($conn[$i]);
}

var_dump(curl_multi_info_read($mh));

以上例程的輸出類似於：

array(3) {
["msg"]=>
int(1)
["result"]=>
int(0)
["handle"]=>
resource(5) of type (curl)
}
array(3) {
["msg"]=>
int(1)
["result"]=>
int(0)
["handle"]=>
resource(7) of type (curl)
}
array(3) {
["msg"]=>
int(1)
["result"]=>
int(0)
["handle"]=>
resource(6) of type (curl)
}
bool(false)
