Сортировка данных массива с объединением даты и времени в php

Question

У меня есть массив, как показано ниже, как сортировать данные по убыванию даты и времени?

$manifest = array(
    array("date"=>2019-02-21,"time"=>04:49:54,"desc"=>"arrived in indonesia"),
    array("date"=>2019-02-25,"time"=>04:02:21,"desc"=>"arrived in soppeng"),
    array("date"=>2019-02-22,"time"=>01:42:51,"desc"=>"arrived in makassar"),
    array("date"=>2019-02-22,"time"=>02:42:51,"desc"=>"arrived in makassar gateway"),
);

Ожидаемый результат:

$manifest = array(
    array("date"=>2019-02-25,"time"=>04:02:21,"desc"=>"arrived in soppeng"),
    array("date"=>2019-02-22,"time"=>02:42:51,"desc"=>"arrived in makassar gateway"),
    array("date"=>2019-02-22,"time"=>01:42:51,"desc"=>"arrived in makassar"),
    array("date"=>2019-02-21,"time"=>04:49:54,"desc"=>"arrived in indonesia")
    );

Спасибо за помощь

Answer 1

Я решил себя, я использую

usort($manifest,function($a,$b){
   return strtotime($b['date']." ".$b['time']) - strtotime($a['date']." ".$a['time']);
});

Спасибо за все, что помогли мне.

Answer 2

$arr = $manifest;

usort($arr, function($a, $b) {
  $ad = new DateTime($a['date'] ." ". $a['time']);
  $bd = new DateTime($b['date']." ". $a['time']);

  if ($ad == $bd) {
    return 0;
  }

  return $ad < $bd ? 1 : -1;
});

Как насчет Массив-мультисорт ?

array_multisort(array_column($manifest, 'date'), SORT_DESC, array_column($manifest, 'time'), SORT_DESC, $manifest);

Просто так

Answer 4

Вы можете использовать rsort(), который будет сортировать массив в порядке убывания.

<code><?php
$manifest = array(
  array("date"=>"2019-02-21","time"=>"04:49:54","desc"=>"arrived in indonesia"),
  array("date"=>"2019-02-25","time"=>"04:02:21","desc"=>"arrived in soppeng"),
  array("date"=>"2019-02-22","time"=>"01:42:51","desc"=>"arrived in makassar"),
  array("date"=>"2019-02-22","time"=>"02:42:51","desc"=>"arrived in makassar gateway")
);

rsort($manifest);

echo '<pre>';print_r($manifest);echo '

';?>

Вывод:

Array
(
    [0] => Array
        (
            [date] => 2019-02-25
            [time] => 04:02:21
            [desc] => arrived in soppeng
        )

    [1] => Array
        (
            [date] => 2019-02-22
            [time] => 02:42:51
            [desc] => arrived in makassar gateway
        )

    [2] => Array
        (
            [date] => 2019-02-22
            [time] => 01:42:51
            [desc] => arrived in makassar
        )

    [3] => Array
        (
            [date] => 2019-02-21
            [time] => 04:49:54
            [desc] => arrived in indonesia
        )

)
