您可以使用uksort
来执行此操作:
uksort($arr, function ($a, $b) {
$t1 = strtotime($a);
$t2 = strtotime($b);
if ($t1 == $t2) {
return 0;
}
return ($t1 > $t2) ? 1 : -1;
});

您可以使用uksort。
uksort - 使用用户定义的比较函数按键对数组进行排序
function cmp($keyA, $keyB)
{
// Your date parsing and comparison
// The comparison function must return an integer less than, equal to,
// or greater than zero if the first argument is considered to be respectively
// less than, equal to, or greater than the second.
// Note that before PHP 7.0.0 this integer had to be in the range
// from -2147483648 to 2147483647.
}
uksort($arr, "cmp")
