You could also use fsockopen or pfsockopen for persistent connection, you can specify the timeout.

http://en.php.net/manual/en/function.pfsockopen.php
http://en.php.net/manual/en/function.fsockopen.php

You can specify the timeout. Look at the examples on the above links.

$fp = fsockopen("www.example.com", 80, $errno, $errstr, 15);

Hope this helps

How about this though?

http://au3.php.net/manual/en/function.stream-set-timeout.php

Example 1. stream_set_timeout() example
<?php
$fp = fsockopen("www.example.com", 80);
if (!$fp) {
echo "Unable to open\n";
} else {

fwrite($fp, "GET / HTTP/1.0\r\n\r\n");
stream_set_timeout($fp, 2);
$res = fread($fp, 2000);

$info = stream_get_meta_data($fp);
fclose($fp);

if ($info['timed_out']) {
echo 'Connection timed out!';
} else {
echo $res;
}

}
?>
