function sort_array_by_value($key, &$array) {
$sorter = array();
$ret = array();
reset($array);
foreach($array as $ii => $value) {
$sorter[$ii] = $value[$key];
}
asort($sorter);
foreach($sorter as $ii => $value) {
$ret[$ii] = $array[$ii];
}
$array = $ret;
}
Contoh Kasus
Sampel array:
$my_array = array(
array(
'id' => 1,
'title' => 'Orange',
'time' => '2014-03-05 03:00:42'
),
array(
'id' => 2,
'title' => 'Banana',
'time' => '2013-01-06 13:05:15'
),
array(
'id' => 3,
'title' => 'Grape',
'time' => '2011-05-15 01:30:45'
)
);
Menyortir data berdasarkan nilai dari title
…
sort_array_by_value('title', $my_array);
print_r($my_array);
Akan menghasilkan urutan seperti ini:
Array
(
[1] => Array
(
[id] => 2
[title] => Banana [time] => 2013-01-06 13:05:15
)
[2] => Array
(
[id] => 3
[title] => Grape [time] => 2011-05-15 01:30:45
)
[0] => Array
(
[id] => 1
[title] => Orange [time] => 2014-03-05 03:00:42
)
)
