Description:
------------
Foreach gives an array instead of the value for each element of an array.


Reproduce code:
---------------
<?
$a = array( "21","22","23","24","25" );
var_dump( $a );
echo "<hr />";
foreach( $a as $v ) {
  var_dump( $v );
  echo "<hr />";
}
?>


Expected result:
----------------
array(5) {
  [0]=>
  string(2) "21"
  [1]=>
  string(2) "22"
  [2]=>
  string(2) "23"
  [3]=>
  string(2) "24"
  [4]=>
  string(2) "25"
}
<hr />string(2) "21"
<hr />string(2) "22"
<hr />string(2) "23"
<hr />string(2) "24"
<hr />string(2) "25"
<hr />

Actual result:
--------------
array(5) {
  [0]=>
  string(2) "21"
  [1]=>
  string(2) "22"
  [2]=>
  string(2) "23"
  [3]=>
  string(2) "24"
  [4]=>
  string(2) "25"
}
<hr />array(2) {
  [0]=>
  string(2) "21"
  [1]=>
  int(0)
}
<hr />array(2) {
  [0]=>
  string(2) "22"
  [1]=>
  int(1)
}
<hr />array(2) {
  [0]=>
  string(2) "23"
  [1]=>
  int(2)
}
<hr />array(2) {
  [0]=>
  string(2) "24"
  [1]=>
  int(3)
}
<hr />array(2) {
  [0]=>
  string(2) "25"
  [1]=>
  int(4)
}
<hr />

Do not file bugs when you have Zend extensions (zend_extension=)
loaded. Examples are Zend Optimizer, Zend Debugger, Turck MM Cache,
APC, Xdebug and ionCube loader.  These extensions often modify engine
behavior which is not related to PHP itself.
