如何按订单状态排序数组

I have an array with date, status and summ:

Array
(
    [0] => Array
        (
            [date] => 2019-07-06 14:01:52
            [status] => paid
            [summ] => 100

        )

    [1] => Array
        (
            [date] => 2019-07-02 12:22:31
            [summ] => 320
            [status] => pending
        )

    [2] => Array
        (
            [date] => 2019-07-01 18:43:58
            [summ] => 100
            [status] => pending
        )

    [3] => Array
        (
            [date] => 2019-06-26 14:01:52
            [status] => canceled
            [summ] => 200
        )

i need to sort this array by status first (1.pending, 2.paid, 3.canceled), and then by date (new at the top).

Order which i nedd:

pending 2019-07-02 12:22:31 pending 2019-07-01 18:43:58 paid 2019-07-06 14:01:52 canceled 2019-06-26 14:01:52

with date i don't have any problems:

usort($new11, function($a, $b) {
    return strtotime($b['date']) - strtotime($a['date']);
});

But how to sort by status in order which i need?

Thanx:)

you can use Spaceship:

<?php

    $new11 = [
        [
            'date' => '2019-07-06 14:01:52',
            'status' => 'paid',
            'summ' => 100,
        ],
        [
            'date' => '2019-07-02 12:22:31',
            'status' => 'pending',
            'summ' => 320,
        ],
        [
            'date' => '2019-07-01 18:43:58',
            'status' => 'pending',
            'summ' => 100,
        ],
        [
            'date' => '2019-06-26 14:01:52',
            'status' => 'canceled',
            'summ' => 200,
        ],
    ];

    $pending = 3;
    $paid = 2;
    $canceled = 1;

    usort($new11, function($a, $b) use ($pending, $paid, $canceled) {
        return (${$b['status']} <=> ${$a['status']}) * 10 +
               (strtotime($b['date']) <=> strtotime($a['date']));
    });


    var_dump($new11);

You could sort it using asort, which order it alphabetically.

If you need it with certain status order, I would recommend use int values to reference the status. Could use some Constraints to define them

You are almost there. You could have an array of priority with values assigned. Then, you could do simple math operations to judge the result.

<?php

usort($new11, function($a, $b) {
    $priority = [
                    'pending' => 1,
                    'paid' => 2,
                    'canceled' => 3
                ];

    $result = $priority[$a['status']] - $priority[$b['status']];
    if($result === 0) return strtotime($b['date']) - strtotime($a['date']);
    return $result;    
});

You can simply use array_multisort to achieve it:

$test = [
    [
        'date' => '2019-07-06 14:01:52',
        'status' => 'paid',
        'summ' => 100,
    ],
    [
        'date' => '2019-07-02 12:22:31',
        'status' => 'pending',
        'summ' => 320,
    ],
    [
        'date' => '2019-07-01 18:43:58',
        'status' => 'pending',
        'summ' => 100,
    ],
    [
        'date' => '2019-06-26 14:01:52',
        'status' => 'canceled',
        'summ' => 200,
    ],
];

array_multisort(
    array_column($test, 'status'),
    SORT_DESC,
    array_column($test, 'date'),
    SORT_DESC,
    $test
);

var_dump($test);

The result would be:

array(4) {
  [0]=>
  array(3) {
    ["date"]=>
    string(19) "2019-07-02 12:22:31"
    ["status"]=>
    string(7) "pending"
    ["summ"]=>
    int(320)
  }
  [1]=>
  array(3) {
    ["date"]=>
    string(19) "2019-07-01 18:43:58"
    ["status"]=>
    string(7) "pending"
    ["summ"]=>
    int(100)
  }
  [2]=>
  array(3) {
    ["date"]=>
    string(19) "2019-07-06 14:01:52"
    ["status"]=>
    string(4) "paid"
    ["summ"]=>
    int(100)
  }
  [3]=>
  array(3) {
    ["date"]=>
    string(19) "2019-06-26 14:01:52"
    ["status"]=>
    string(8) "canceled"
    ["summ"]=>
    int(200)
  }
}
