laravel按日期对数组进行排序 [英] laravel sort an array by date

问题描述

你好朋友，我有一个看起来像这样的数组:

hello friends I have an array that looks like this:

array:3 [▼
  0 => array:6 [▼
    "date" => "2016-05-31 15:08:33"
    0 => "31 May 16"
    1 => "aze"
    2 => "2"
    3 => "hi"
    4 => "487841464704194.jpg"
  ]
  1 => array:6 [▼
    "date" => "2016-05-31 15:26:09"
    0 => "31 May 16"
    1 => "aze"
    2 => "2"
    3 => "hey"
    4 => "487841464704194.jpg"
  ]
  2 => array:6 [▼
    "date" => "2016-06-01 11:33:06"
    0 => "01 Jun 16"
    1 => "aze"
    2 => "2"
    3 => "Dm me please"
    4 => "487841464704194.jpg"
  ]
]

我的目标是按date对其进行排序.所以从新到旧.

My goal is to sort it by the date. So from new to old.

如果尝试这样做:

$comarrSorted = $comarr->sortByDesc('date');
dd($comarrSorted);

但是我收到这个讨厌的错误:

But I get this nasty error:

Call to a member function sortByDesc() on array

任何人都可以帮助我吗?我猜该错误是由于它是一个收集函数引起的?使用此函数无法对我的数组进行排序吗?

Anyone can help me out? I guess the error is caused because it's a collection function? Is it not possible to sort my array with this function?

非常感谢！

推荐答案

您必须创建自己的函数

array_sort_by_column($array, 'date');


function array_sort_by_column(&$array, $column, $direction = SORT_ASC) {
    $reference_array = array();

    foreach($array as $key => $row) {
        $reference_array[$key] = $row[$column];
    }

    array_multisort($reference_array, $direction, $array);
}
