Not true.  If you set it to null, it still exists...it's just null.  If 
you unset it, the variable no longer exists.

$_SESSION['total'] = null;
if ( isset ( $_SESSION['total'] ) ) {
	echo ( "Yes" );
} else {
	echo ( "No" );
}

unset ( $_SESSION['total'] );
if ( isset ( $_SESSION['total'] ) ) {
	echo ( "Yes" );
} else {
	echo ( "No" );
}
