php question

[michael2002]

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

currently i use something like :

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 Code:

<?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.
