} I tested it on 4.3.4 and 5.0 RC1, and it worked. Is passing an undefined variable as a reference parameter a legal thing to do in PHP?
That bring up an interesting point: error_reporting(E_ALL); function test_func(&$oink) { echo $oink; } test_func($moo); executing this block does not fire an E_NOTICE. S So, how I see the code:

inside the function you have already a variable named $oink so there won't be a E_NOTICE for unknown var. The variable is "linked" to somewhere outside but that doesn't matter. I think it has in common with the unset() behaviour on variables visible with "global" keyword. Andrey
