Bug description: foreach modifies array pointer
Description:
------------
In the code example below, when entering the for-loop, the arraypointer is
at position 1 (the 2nd element).
When you comment out the foreach-loop before OR insert the reset-line,
output starts - as expected - at the first array element (posistion 0).
This means "foreach" modifies the array pointer, although the
documentation says "foreach operates on a copy of the specified array and
not the array itself. Therefore, the array pointer is not modified"
Testing with versions 4.4.7/5.2.3/5.3dev(2007-11-08-Snap) of Windows zip
package and 4.4.7/5.2.1 on gentoo (5.2.3 not testet on linux) shows correct
behavior.
Reproduce code:
---------------
$t=range('a','c');
foreach ($t AS $key => $profil){
$t[$key]="1";
}
//reset($t);
for ($i=0;$i<sizeof($t);$i++){
echo key($t) . "->".current($t)."\n";
next ($t);
}
print_r($t);
Expected result:
----------------
version 5.2.3:
0->1
1->1
2->1
Array
(
[0] => 1
[1] => 1
[2] => 1
)
Actual result:
--------------
version 5.2.4:
1->1
2->1
->
Array
(
[0] => 1
[1] => 1
[2] => 1
)
