Description:
------------
---
From manual page: http://www.php.net/function.trim#refsect1-function.trim-
returnvalues
---

Taken from Empty function documentation:
will not work: empty(trim($name)). Instead, use trim($name) == false.

Test script:
---------------
unset($name);
echo empty(trim($name)); //FAILS
echo trim($name); //FALSE
