Bug description: Assigning array values inside foreach and array pointer
Description:
------------
In PHP 5.2.4 when I set array values inside a foreach, the array pointer
is moved to the second element of the array or, better, to the element
after the first modified element of the array.
In PHP 5.2.3 the array pointer was not moved.
Moreover this does not happen if i assign the array elements outside the
foreach.
Reproduce code:
---------------
$parameters = array(
'a' => 1,
'b' => 2,
'c' => 3,
'd' => 4
);
echo "\$parameters key before foreach: " . key($parameters) . "\n";
foreach($parameters as $key => $value) {
$parameters[$key] = "s" . $value;
}
echo "\$parameters key after foreach: " . key($parameters) . "\n";
echo "\$parameters key before foreach: " . key($parameters) . "\n";
$parameters['a'] = "s" . 1;
$parameters['b'] = "s" . 2;
$parameters['c'] = "s" . 3;
$parameters['d'] = "s" . 4;
echo "\$parameters key after foreach: " . key($parameters) . "\n";
Expected result:
----------------
$parameters key before foreach: a
$parameters key before foreach: a
$parameters key before foreach: a
$parameters key before foreach: a
Actual result:
--------------
$parameters key before foreach: a
$parameters key before foreach: b
$parameters key before foreach: a
$parameters key before foreach: a
