Bug description: array_multisort : Array sizes are inconsistent
Description:
------------
I'm not sure is a bug but I don't understand why the first block is
executed correctly whereas the second one (same code) returns with this
warning:
Warning: array_multisort() [function.array-multisort]: Array sizes are
inconsistent in /usr/local/httpd-2.2.0/htdocs/test/multisort.php on line
27
Reproduce code:
---------------
<?
error_reporting(E_ALL);
// first block
$data = array();
$data[2] = array('volume' => 67, 'edition' => 2);
$data[3] = array('volume' => 86, 'edition' => 1);
foreach ($data as $key => $row) {
$volume[$key] = $row['volume'];
$edition[$key] = $row['edition'];
}
array_multisort($volume, SORT_DESC, $edition, SORT_ASC, $data);
// second block (equal to first block)
$data = array();
$data[2] = array('volume' => 67, 'edition' => 2);
$data[3] = array('volume' => 86, 'edition' => 1);
foreach ($data as $key => $row) {
$volume[$key] = $row['volume'];
$edition[$key] = $row['edition'];
}
array_multisort($volume, SORT_DESC, $edition, SORT_ASC, $data);
?>
Expected result:
----------------
Both blocks give the same result.
Actual result:
--------------
Warning: array_multisort() [function.array-multisort]: Array sizes are
inconsistent in /usr/local/httpd-2.2.0/htdocs/test/multisort.php on line
