PHP question

Just a followup. I added the following lines that were very useful. 
ini_set('display_errors', 1);
ini_set('display_startup_errors ',1);
There were 2 problems. One was a result of register_globals being off.
I fixed that with:
$VAR = $_POST['VAR'];
The other was I was using $PHP_SELF, and it is not $_SERVER['PHP_SELF'].

The script now works correctly. 
But, one more quesiton. When I have the debugging turned on, it reports
that $_POST['VAR'] is not set.
Notice: Undefined index: VAR in script.php on line 6
I can fix this with:
if (isset($_POST['VAR'] )
	$VAR = $_POST['VAR'];
Is there a better way of doing this to avoid the messages.
