Convert eloquent result to associative array in Laravel
提问by Mehdi
How can convert the result from eloquent to associative array. I need to select tow column and have one as key and another as value. Here is the closet I got, however the value is an array. I want it to be only "my_value" column.
如何将结果从 eloquent 转换为关联数组。我需要选择两列并将一个作为键，另一个作为值。这是我得到的壁橱，但值是一个数组。我希望它只是“my_value”列。
$array = Post::select('my_key','my_value')->get()->keyBy('my_key')

You should use lists(Laravel 5.1) or pluck(Laravel 5.2+):
您应该使用lists(Laravel 5.1) 或pluck(Laravel 5.2+)：
$array = Post::lists('my_value', 'my_key');
or
或者
$array = Post::pluck('my_value', 'my_key');

I found a way to do so, I'm not sure whether it's proper way to do this performance wise though...
我找到了一种方法，但我不确定这是否是明智地执行此操作的正确方法......
$array = Post::select('my_key','my_value')->get()->mapWithKeys(function ($item) {
return [$item['my_key'] => $item['my_value']];
})->toArray();
