<?php

class XmlTest {



    function test_ref(&$test) {

        $test = "ok";

    }



    function test($test) { }



    function run() {

        $ar = array();

        $this->test_ref($ar[]);

        var_dump($ar);

        $this->test($ar[]);

    }

}



$o = new XmlTest();

$o->run();

?>

This should always have thrown a fatal E_ERROR, because [] cannot be used for reading in PHP. It is invalid code in PHP 4.4.2 and PHP 5.0.5 upward.
