Laravel 8 sortKeys() {#collection-method}

sortKeys 方法通过底层关联数组的键来对集合进行排序：

$collection = collect([
    'id' => 22345,
    'first' => 'John',
    'last' => 'Doe',
]);

$sorted = $collection->sortKeys();

$sorted->all();

/*
    [
        'first' => 'John',
        'id' => 22345,
        'last' => 'Doe',
    ]
