Your preg isn't going to return the URLs (even if it works), it's going
to return the labels of the links. But anyways...

<?php

$content = implode( '', @file( 'http://www.php.net' ) );

if( preg_match_all(
        '#(<a[^>]+href[^>]+>)(.*)</a>#Umis', $content, $bits ) )
{
    print_r( $bits );
}

?>

Cheers,
Rob.
