you can set http timeout. (not tested)

<?php $ctx = stream_context_create(array(     'http' => array(         'timeout' => 30      ) )); file_get_contents("http://example.com/", 0, $ctx);

edit: don't know why isn't working code you. if don't manage bring work may want give curl try. faster (but don't know if faster...).
if work you, use curl_setopt function set timeout time curlopt_timeout flag.
