Laravel按日期排序集合

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?

感谢。

尝试like this

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

您可以尝试

$transaction->groupBy('date');

确保$ transaction是一个集合;

我遇到了同样的问题。我创建了这个宏。

@foreach ($players as $key => $player)

我这样用:

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