Description:
------------
In this php version the internal array pointer after foreach is not always NULL even after the full cicle is made. Instead it points to the next key after the one which was current when the first change was made to the array we are currently iterating.

Reproduce code:
---------------
$ar  = array('val1', 'val2', 'val3');
var_dump(key($ar));
echo '<br>';
foreach ($ar as $key=>$val)
{	
	echo $key.'=>'.$val.'<br>';	
}
var_dump(key($ar));
echo '-------';
foreach ($ar as $key=>$val)
{	
	echo $key.'=>'.$val.'<br>';	
	$ar[2] = $ar[2];
}
var_dump(key($ar));
echo '-------';
foreach ($ar as $key=>$val)
{	
	echo $key.'=>'.$val.'<br>';	
	if ($key==1) $ar[2] = $ar[2];
}
var_dump(key($ar));

Expected result:
----------------
int(0)
0=>val1
1=>val2
2=>val3
NULL 
-------
0=>val1
1=>val2
2=>val3
NULL
-------
0=>val1
1=>val2
2=>val3
NULL

Actual result:
--------------
int(0)
0=>val1
1=>val2
2=>val3
NULL 
-------
0=>val1
1=>val2
2=>val3
int(1)
-------
0=>val1
1=>val2
2=>val3
int(2)
