Description:
------------
When is used globalized array into recursion method, there is an odd behaving of foreach on this array in each recursion call. It seems, that there is no copy of array for foreaching, but reference??? - internal array pointer is changed in should-be-copy of array. (ref.(php-manual: foreach): Note:  Also note that foreach operates on a copy of the specified array and not the array itself.)
(btw: it is not bug #22879)

Reproduce code:
---------------
<?php
//--------- ODD -------

	echo "<br>global:<br>";	

	$globvar = array(1,2,3);
	
	Recursion(1);	
	function Recursion($nr)
	{
	  global $globvar;
	  
	  echo "in:".$nr."<br>";
	  
	  foreach($globvar as $valnr)
	  {
	    if($valnr > $nr)
	    {
		    echo $valnr."<br>";
                    Recursion($valnr);
	    }
	  }
	  
	  echo "out:".$nr."<br>";
	}


//-------- EXPECTED -----------

	echo "<br>local:<br>";

	$locvar = array(1,2,3);

	RecursionLoc(1, $locvar);

	function RecursionLoc($nr, $locvar)
	{
	  echo "in:".$nr."<br>";

	  foreach($locvar as $valnr)
	  {
	    if($valnr > $nr)
	    {
		    echo $valnr."<br>";
		    RecursionLoc($valnr, $locvar);
	    }
	  }

	  echo "out:".$nr."<br>";
	}

?>

Expected result:
----------------
global:
in:1
2
in:2
3
in:3
out:3
out:2
3
in:3
out:3
out:1

local:
in:1
2
in:2
3
in:3
out:3
out:2
3
in:3
out:3
out:1

Actual result:
--------------
global:
in:1
2
in:2
3
in:3
out:3
out:2
out:1

local:
in:1
2
in:2
3
in:3
out:3
out:2
3
in:3
out:3
out:1
