Description:
------------
get_class() invoked with no argument, always return the original classname, in which it is first referenced.

Reproduce code:
---------------
#!/bin/php

<?php


class parentCls{
        static function initPStatic(){
                echo("parentCls::initPStatic said get_class()=='".get_class()."'\n");
                echo("\n");
        }
        function initP(){
                echo("parentCls::initP said get_class()=='".get_class()."'\n");
                echo("\n");
        }
}

class childCls extends parentCls{
}

childCls::initPStatic();
$c=new childCls();
$c->initP();

?>

Expected result:
----------------
parentCls::initPStatic said get_class()=='childCls'

parentCls::initP said get_class()=='childCls'

Actual result:
--------------
parentCls::initPStatic said get_class()=='parentCls'

parentCls::initP said get_class()=='parentCls'
