I'm trying to understand static methods in a test class. Reading the
manual, it says: "A member or method declared with static can not be
accessed with a variable that is an instance of the object and cannot
be re-defined in an extending class."

Test code:
========

<?php

class B
{
        private $str;
        
        public final function __construct()
        {
                $this->str = 'Hello world';
        }
        
        public function showB()
        {
                echo $this->str, '<br>';
                echo 'Showing B<br>';
                $this->TestStatic();
        }

        
        public static function TestStatic()
        {
                echo '<br>Inside Static<br>';
        }
}

echo error_reporting() . '<br>';

$test = new B;
$test->TestStatic();
$test->showB();
echo "-- END --";
?>

Output:
=====

4095

Inside Static            --> Called by $test->TestStatic()
Hello world
Showing B

Inside Static            --> Called from $test->showB with $this->TestStatic()
-- END --

Comments:
========

I'm running PHP 5.0.2 and error_reporting = E_ALL | E_STRICT. As
reported in the output, the values for error_reporting are well set
(4095 == E_ALL | E_STRICT)

with zend engine 1.3 compatiblity on ?
