Description:
------------
The inital value of a static variable in a non-static method should take care 
about the current instance. The initialization should be done when a method of 
the instance is called, and not only when the method is first called in the 
script. The local static variable should be interpreted as an object variable 
that is visible only in the declaring method.

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

class StatTest {
	
	function statvartest() {
		static $var = 'initial';
		echo $var."\n";
		if ($var == 'initial') {
			$var = 'changed';
		}
	}
}

$testA = new StatTest;
$testA->statvartest();
$testA->statvartest();

$testB = new StatTest;
$testB->statvartest();
$testB->statvartest();



Expected result:
----------------
initial
changed
initial
changed


Actual result:
--------------
initial
changed
changed
changed
