note 71447 added to function.file-exists

Don't use this function in loops as it's pretty slow:

leibwaechter at web dot de
<?php
function url_exists($url)
{
 $handle = fopen($url, "r");
 if ($handle === false)
  return false;
 fclose($handle);
 return true;
}
?>

Best in situations where it is a one off. Better still try
to do without it. Checking lots of addresses with this
involves lots of dns lookups etc.
