Description:
------------
don't work in the class - but if I do the same action NOT IN THE CLASS METHOD - it works


<form action="test.php" method="post">
<input type="text" name="name" />
<input type="submit" />
</form>
<?php
error_reporting (E_ALL); 
if (!empty($_POST['name'])) {
$z = '_POST';
echo ${$z}['name'];
}
?>

this works fine

Reproduce code:
---------------
<form action="test.php" method="post">
<input type="text" name="name" />
<input type="submit" />
</form>
<?php
error_reporting (E_ALL); 
if (!empty($_POST['name'])) {
	class blah {
		function tester () {
			$z = '_POST';
			echo ${$z}['name'];
		}
	}
	$a = new blah;
	$a->tester();
}
?>

Expected result:
----------------
the value I wrote in the form

Actual result:
--------------
