Bug description:array_multisort converts "digit only" string keys to default
numeric keys:0,1..
Description:
------------
Hello,
I think I found a bug in array_multisort, when trying to sort a
multi-dimensional array, which has string keys containing only digits.
On the resulting array, those keys are suppressed, and replaced by '0' for
the first one, '1' for the second...
I had this error on PHP version 5.3.6, and on the last PHP 5.4 Snap
revision: 322462, downloaded from php.net (tested with no .ini file)
Test script:
---------------
$t = array(
'AZE' => array('SORT' => 'order #2', 'FOO' => 'xx'),
'123' => array('SORT' => 'order #3', 'FOO' => 'xx'),
'RTY' => array('SORT' => 'order #5', 'FOO' => 'xx'),
'654' => array('SORT' => 'order #1', 'FOO' => 'xx'),
'UIO' => array('SORT' => 'order #4', 'FOO' => 'xx'),
);
$W_ORDER = array();
foreach($t as $key => $row)
$W_ORDER[(string)$key] = $row['SORT'];
array_multisort(
$W_ORDER, SORT_ASC, SORT_STRING,
$t
);
print_r($t);
Expected result:
----------------
Array
(
[654] => Array
(
[SORT] => order #1
[FOO] => xx
)
[AZE] => Array
(
[SORT] => order #2
[FOO] => xx
)
[123] => Array
(
[SORT] => order #3
[FOO] => xx
)
[UIO] => Array
(
[SORT] => order #4
[FOO] => xx
)
[RTY] => Array
(
[SORT] => order #5
[FOO] => xx
)
)
Actual result:
--------------
Array
(
[0] => Array
(
[SORT] => order #1
[FOO] => xx
)
[AZE] => Array
(
[SORT] => order #2
[FOO] => xx
)
[1] => Array
(
[SORT] => order #3
[FOO] => xx
)
[UIO] => Array
(
[SORT] => order #4
[FOO] => xx
)
[RTY] => Array
(
[SORT] => order #5
[FOO] => xx
)
)
