php question

what is the best method to test if a file on a remote server (url) exist?

currently i use something like :

Code:

if($x=file($url)) echo("file exist");

else echo("file don't exist");

but this code in the case that the file is not existing take long time to execute :(

there is any faster method to test if a file on a remote server exist or not?

<?php

$file = fopen ("http://www.example.com/", "r");

if (!$file) {

    echo "<p>Unable to open remote file.\n";

    exit;

}

else {blah blah blah;

}

fclose($file);

?>

change the first line to this so you don't generate any errors. $file = @fopen ("http://www.example.com/", "r");

Don't forget the speed of the remote server is factored in here, not just your checking code.
