Description:
------------
Is no longer possible to name a class methods using names that are reserved keywords like : 'break', 'for', 'goto'.  It used to work with previous php versions.

If this is a 'feature', what's the point ?




Test script:
---------------
<?php

class foo {
        static function for() {
                echo "1";
        }

        static function goto() {
                echo "2";
        }

}

foo::for();
foo::goto();

Expected result:
----------------
Display: 12


Actual result:
--------------
PHP Parse error:  syntax error, unexpected T_FOR, expecting T_STRING in /etc/asterisk/manager.d/test.php on line 4

I don't know what your "previous" version was, but the same error occurs with PHP 
5.1.6 so this has been a language feature for a very long time.

Also see http://bugs.php.net/51782 about the introduction of new keywords in 
recent versions.

Strange, I've notice the bug after updating from Ubuntu karmic. Looking now at 
the package.ubuntu.com I see that karmic came with php 5.2.10

I'm 100% sure that I didn't had this bug before the update

I notice that the other bug you've pointed me to, states that the problem 
happens starting with version 5.3.2 also.

for the record:
I've tested this, and the last 5.2 version(5.2.17) behaves the same way:

Parse error: syntax error, unexpected T_FOR, expecting T_STRING in 
/home/tyrael/testbug.php on line 3
