When you convert the string "add" to a boolean, it equates to true.
I'm assuming you want to be using a conditional expression rather than an
assignment statement. Either this was a typo, or you should really read a
lot of introductory material on PHP's syntax, as I'm guessing this is your
first programming language. Start with the PHP manual:
http://www.php.net/manual/
Expressions are discussed here:
http://www.php.net/manual/en/language.expressions.php
PHP's conditional expressions are given as follows:
--------------------------------------------------
PHP supports > (bigger than), >= (bigger than or equal to), == (equal), !=
(not equal), < (smaller than) and <= (smaller than or equal to).
--------------------------------------------------
Hope that helps.
