Description:
------------
I'm modeling my data as objects and would like it to be as transparent 
as possible.  As such, gettype($myObj) should return a type value other 
than 'object.'  Can you implement a magic method __gettype() which 
expects the return value to be a string?

Reproduce code:
---------------
---
From manual page: language.oop5.magic
---
class MyInt {
    public function __construct ($val){
        $this->val = $val;
    }
    public function __gettype () {
        return 'int';
    }
}

$foo = new MyInt(5);
$int = (int) 5;

if (gettype($foo) == gettype($int)){
    echo gettype($foo); // Should echo 'int'
} else {
    echo "Fail."
}

Expected result:
----------------
Ideally, the code above would echo "int" as the type of MyInt $foo is 
overridden by the __gettype magic method to be 'int', just as it is for 
$int.

Actual result:
--------------
The code above will echo "Fail."  You may also need to implement a 
type-agnostic equivalent of __toString() like __return() that does, 
essentially:

public function __return () {
    return ($this->__gettype()) $this->_value;
}

This would allow me to compare:

($foo === $int); // This should evaluate to true.

gettype should really give the type, your class will always behave differently from an integer (just think about by value and by ref)
