我正在使用Laravel 4.2开发一个项目，我有一行从一个名为Gifts
的表中检索一些行$theGifts = Gift::whereIn('id', $giftImages)->get();
此变量$giftImages是一个数组，值按此顺序排序
Array
(
[0] => 5
[1] => 2
[2] => 3
[3] => 4
)
当我输出这个$theGifts时，检索到的结果与ids数组的顺序不同，我需要它的顺序相同..
我如何确保订单相同？我正在使用控制器中对象的数据，而不是顺便提供的视图。
Gift::all()的打印输出如下（如果有人需要比较）..

答案 0 :(得分：1)
我相信这会为你做到：
Gift::whereIn('id', $giftImages)
->orderBy(DB::raw('FIELD(id, ' . implode(',', $giftImages) . ')'), 'ASC')
->get();
取自this question。您必须使用DB::raw()，因为Laravel不提供本机方式来执行此操作。未经测试...
