<?
        function xmpdump($xValue, $sLabel="")
        {
                echo "$sLabel<xmp>";
                var_dump($xValue);
                echo "</xmp>";
        }

        class test
        {
                var $sValue;
                var $Count = 0;
        
                function getTest(&$refObj)
                {
                        if (isset($this->sValue))
                        {
                                $refObj = &$this->sValue;
                                xmpdump($refObj, "Reference before being passed back");
                                return;
                        }
                        else
                        {
                                $refObj = "phil".$this->Count;
                                $this->Count++;
                                $this->sValue = &$refObj;
                                xmpdump($refObj, "Value before being passed back");
                                return;
                        }
                }
        }
        
        $tst = new test();

        $tst->getTest($tstObj0);
        xmpdump($tstObj0, "Value after being passed back");
        
        $tst->getTest($tstObj1);
        xmpdump($tstObj1, "Refence after being passed back");
?>

The dump of $tstObj1 is NULL, despite the dump of $refObj immediately before it in the function working correctly.
