Operating system: Linux 2.4.20
PHP version: 4.3.10
PHP Bug Type: Zend Engine 2 problem
Bug description: foreach behaviour change in 4.3.10
Description:
------------
Apparently, the foreach loop such as "foreach ($array as $value)" puts
some kind of index-value array into $value. This differs from what the
documentation says and does not seem to appear in changelog or make any
sense. The code below produces different results on 4.3.9 and 4.3.10
Reproduce code:
---------------
<?php
$a = array(
'ab' => array(
'a' => 1,
'b' => 2
),
'cd' => array(
'c' => 3,
'd' => 4
)
);
foreach ($a as $key => $array) {
echo '<br />key ' . $key . ', array: ';
var_dump($array);
foreach ($array as $datafield) {
echo '<br />key ' . $key . ', subarray element: ';
var_dump($datafield);
}
}
?>
Expected result:
----------------
PHP 4.3.9:
key ab, array: Array ( [a] => 1 [b] => 2 )
key ab, subarray element: 1
key ab, subarray element: 2
key cd, array: Array ( [c] => 3 [d] => 4 )
key cd, subarray element: 3
key cd, subarray element: 4
Actual result:
--------------
PHP 4.3.10:
key ab, array: Array ( [a] => 1 [b] => 2 )
key ab, subarray element: Array ( [0] => 1 [1] => a )
key ab, subarray element: Array ( [0] => 2 [1] => b )
key cd, array: Array ( [c] => 3 [d] => 4 )
key cd, subarray element: Array ( [0] => 3 [1] => c )
key cd, subarray element: Array ( [0] => 4 [1] => d )
