Description:
------------
After updating from PHP 5.1.6 some scripts didn?t work.
Problem is the standard behavior from casting objects into strings without an explicit defined __toString() method

Reproduce code:
---------------
<?php
class test
{
	private $var = "test";
	public function __construct() {}
}

$object = new test();
echo $object;
?>

Expected result:
----------------
Object id #1

Actual result:
--------------
Catchable fatal error: Object of class test could not be converted to string in C:\xampp\htdocs\classtest.php on line 9
