Description:
------------
the documentation for each http://www.php.net/manual/en/function.each.php has a caution which was true for php up to 4.3.11, but it's not for 4.4.1 anymore. 

Reproduce code:
---------------
		$array   = array('a', 'b', 'c', 'd', 'e', 'f', 'g');
		$breakAt = 3;
		$i=0;
		while (list($key, $val) = each($array)) {
			if ($i > $breakAt) break;
			$i++;
		}
		$brray = $array;
		$aCurrent = current($array);
		$bCurrent = current($brray);
		
    $actual   = $aCurrent;
    $expected = 'a';
    $this->assertEquals($expected, $actual, "failed? could be a good thing. check the code.");
		
    $actual   = $bCurrent;
    $expected = 'f';
    $this->assertEquals($expected, $actual, "failed? could be a good thing.");


Expected result:
----------------
a or f

Actual result:
--------------
a or f
