No, that function can only be applied to a same server where the script is
being run off, it will not do anything to a remote server.

After thinking a bit, I came up with this code (some parts were removed for
clarity):

$handle = @fopen($url, 'r');
if ($handle===false) { //not on server }
else fclose($handle); //on server

If anyone has any ideas or other ways, I am all ears.

Thanks.
