我需要按键值对数组php进行排序。我的数组:

Array
(
    [1430039342393636453] => Array
        (
            [0] => Array
                (
                    [thrid] => 1430039342393636453
                    [uid] => 19748
                    [flag] => 1
                    [timestamp] => 1363791789
                    [date] => Mar 20
                    [content_preview] => 
                    [content] => 
                )
        )
[1430750471744336569] => Array
        (
            [0] => Array
                (
                    [thrid] => 1430750471744336569
                    [uid] => 19870
                    [flag] => 1
                    [timestamp] => 1364469959
                    [date] => Mar 28
                    [content_preview] =>
                    [content] =>
                )
            [1] => Array
                (
                    [thrid] => 1430750471744336569
                    [uid] => 19874
                    [flag] => 1
                    [timestamp] => 1364472417
                    [date] => Mar 28
                    [content_preview] => 
                    [content] => 
                )
)

我需要按timestamp排序主数组和子数组。suggesitons吗?

使用sort对关联数组进行排序。

对PHP中的关联数组进行排序

试试这样写:

private function sort($sort) {
    foreach($sort as &$arr) { //use a reference because usort uses references to manipulate your array.
                            //if you don't pass by reference you'll never see the sort
        usort($arr, function($a, $b) { return $a['timestamp'] - $b['timestamp'];
    }
    usort($sort, function($a, $b) { return key($a) - key($b); }
    return $sort;
}
