Answer 1

Do not use any of the suggested versions of PHP_SELF. It is a security nightmare, opening up your PHP to a multitude of possible injection attacks.

What are you trying to achieve? Generate the URL for a form sending to itself? Use action="" for that - it is a valid approach and will always use the URL for sending the form as for loading.

If you must know the requested script, use $_SERVER['SCRIPT_NAME'] instead.

Answer 2

You are using $PHP_SELF it should be

echo $_SERVER['PHP_SELF'] ;

Or

$PHP_SELF = &$_SERVER['PHP_SELF'];
echo $PHP_SELF ;

You can also have

define("PHP_SELF",$_SERVER['PHP_SELF']); 
echo PHP_SELF ;

Answer 3

Are you trying to access $_SERVER['PHP_SELF'] ?
