Class type hints do not work with non-classes, like 
strings, integers, and arrays.

The error message is telling you it's expecting a class 
named "string." :)

Er... Could this be implemented in a future release, please? (I'm a C++ programmer and variables with no types make me ill :P !!!)

Note that the page http://fr.php.net/zend-engine-2.php shows an Exception class that has this "problem":

class Exception {
   function __construct(string $message=NULL, int code=0) {...}

The page should corrected (or the feature should be implemented to match the page!!!)

Thanks!

The only possible thing we will add is "array" and "resource" as type hints, but never "String" "int"  or "float", as PHP is a loosly typed language unlike Jabba.
