Solved: self referring URLs PHP Direct-Eval

[SkyStryder]

What is the recommended way to create self referring URLs on these pages.
This page takes arguments and I need to create links that will refer to the page
itself. In the example below, how can I create $SName from the variables within
PHP Direct-Eval?

$a. = '<a href="$SName?cm=pvideo">Video</a>';

Thank you!
Rick

This works well.

function FindSelf ()
{
   $Path = $_SERVER['REQUEST_URI'];
   $SName = substr($Path, 0, strpos($Path, "&"));
   if ($SName === "") $SName = $Path;
   return $SName; 
}
