Description:
------------
---
From manual page: http://www.php.net/control-structures.foreach

array expression is not reevaluated on each loop
Test script:
---------------
$a = array(1 => array("test1"), 2, 3, 17);
foreach ($a as $a) {
var_dump( $a );
}
Expected result:
----------------
array(1) {
[0]=>
string(4) "test1"
}
string(4) "test1"
Actual result:
--------------
array(1) {
[0]=>
string(4) "test1"
}

int(3)
int(17)
