Hi crimso,

congrats that you got it fixed!

Let me mention that NULL is a special value. An empty string is NOT NULL. An empty string is still a string.

The interactive php interpreter may help you with testing of code.

Code:
hellfire@hellfire:~$ php -a
Interactive mode enabled
php > var_dump("");
string(0) ""
php >

The mentioned function gettype() and var_dump() help you a lot in debugging!
