Description:
------------
The new __toString() magic method wont work

Reproduce code:
---------------
The new __toString() magic method allows you to overload the object to string conversion:
<?php 
class Foo { 
   function __toString() { 
       return "What ever"; 
   } 
} 

$obj = Foo; 
$str = (string) $obj; // call __toString() 
echo $obj; // call __toString() 
?> 

Expected result:
----------------
What ever

Actual result:
--------------
Object#n

Your script is bogus:
Notice: Use of undefined constant Foo - assumed 'Foo' in - on line 8

Sorry, assumes that

$obj = new Foo();
 [2004-10-14 07:58 UTC] derick@php.net 
Still works as expected:

derick@kossu:~$ php-5.0dev bug30421.php

What ever


derick@kossu:~$ php-5.0dev -v bug30421.php

// A construction 
echo $obj; 
// realy works as expected and the output is a string: What ever

// But using this object in string context or explicit
// type casting (string) return unexpected result:
echo "Any string $obj";
// Output: Any string Object id #1

Yes, this is expected behavior. No bug here.
