$ch1 = curl_init();
$ch2 = curl_init();
$ch3 = curl_init();

// set URL and other appropriate options
curl_setopt($ch1, CURLOPT_URL, $url[1]);
curl_setopt($ch1, CURLOPT_HEADER, 0);
curl_setopt($ch1, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch2, CURLOPT_URL, $url[2]);
curl_setopt($ch2, CURLOPT_HEADER, 0);

$mh = curl_multi_init();

//add the two handles
curl_multi_add_handle($mh,$ch1);
curl_multi_add_handle($mh,$ch2);
curl_multi_add_handle($mh,$ch3);


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


echo "<br>$mh[0]";
echo "<br>$mh[1]";
echo "<br>$mh[2]";


//close the handles
curl_multi_remove_handle($mh, $ch1);
curl_multi_remove_handle($mh, $ch2);
curl_multi_remove_handle($mh, $ch3);
curl_multi_close($mh);

echo "<br>Stop time: ".date("H:i:s").'<br>';
