responding to joemamacow at hotmail dot com comment:
if you are using isset() to check is the variable set, the more logically and clear way to
"delete" the variable is to use unset() (http://www.php.net/unset ) function:
<?php
unset($variable);
?>
Of course setiing variable value to NULL is also OK.
