PHP按包含日期的元素對(duì)多維數(shù)組進(jìn)行排序我有一個(gè)數(shù)組，如：Array([0] => Array
(
[id] => 2
[type] => comment [text] => hey [datetime] => 2010-05-15 11:29:45
)[1] => Array
(
[id] => 3
[type] => status [text] => oi [datetime] => 2010-05-26 15:59:53
)[2] => Array
(
[id] => 4
[type] => status [text] => yeww [datetime] => 2010-05-26 16:04:24
))有人能建議一種基于datetime元素排序/排序的方法嗎？

usort()
function date_compare($a, $b){
$t1 = strtotime($a['datetime']);
$t2 = strtotime($b['datetime']);
return $t1 - $t2;} usort($array, 'date_compare');編輯

foreach ($originalArray as $key => $part) {
$sort[$key] = strtotime($part['datetime']);

array_multisort($sort, SORT_DESC, $originalArray);array_multisort(array_map('strtotime',array_column($originalArray,'datetime')),
SORT_DESC,
