Laravel按日期排序集合

Question

我有这个收集结果:

$result = [{
    "date": "2016-03-21",
    "total_earned": "101214.00"
},
{
    "date": "2016-03-22",
    "total_earned": "94334.00"
},
{
    "date": "2016-03-23",
    "total_earned": "96422.00"
},
{
    "date": "2016-02-23",
    "total_earned": 0
},
{
    "date": "2016-02-24",
    "total_earned": 0
},
{
    "date": "2016-02-25",
    "total_earned": 0
}]

我想按日期对结果进行排序:

$sorted = $transaction->sortBy('date')->values()->all();

但我没有得到预期的结果:

[{
    "date": "2016-02-23",
    "total_earned": 0

},
{
    "date": "2016-02-24",
    "total_earned": 0
},
{
    "date": "2016-02-25",
    "total_earned": 0
},
{
    "date": "2016-03-22",
    "total_earned": "94334.00"
},
{
    "date": "2016-03-21",
    "total_earned": "101214.00"
},
{
    "date": "2016-03-23",
    "total_earned": "96422.00"
}]

正如您所看到的,第2个月的所有内容都排序正确.然而在第3个月它开始搞砸了.(实际结果比这更长,并且从第3个月开始搞砸了)

任何使其排序正确的解决方案？

谢谢.

Answer 1

尝试是这样的：

$sorted = $transaction->sortBy(function($col)
{
    return $col;
})->values()->all();

Answer 2

我有同样的问题。我创建了这个宏。

Collection::macro('sortByDate', function (string $column = 'created_at', bool $descending = true) {
/* @var $this Collection */
return $this->sortBy(function ($datum) use ($column) {
    return strtotime(((object)$datum)->$column);
}, SORT_REGULAR, $descending);

});

我像这样使用它：

$comments = $job->comments->merge($job->customer->comments)->sortByDate('created_at', true);
