From manual page: http://www.php.net/function.strlen#Description
---
I found a "bug" when upgrading from php 5.2.9.

In 5.2.9 stelen when invoked on an array would return the size of the array
In 5.3.3 strlen when invoked on an array returns null

This behavior was sort of unexpected. The documentation might want to reflect the change - or the function should maybe throw a warning or error.

Confirmed, sort of. 

PHP versions prior to 5.3 will always return 5, because the string 'Array' has a 
length of 5 (it also emits an E_NOTICE error). As of 5.3, it returns NULL and 
emits an E_WARNING error.
