Eloquent 只获取一列作为数组

如何使用eloquent在laravel 5.2中只获取一列作为一维数组?

How to get only one column as one dimentional array in laravel 5.2 using eloquent?

我已经尝试过:

$array = Word_relation::select('word_two')->where('word_one', $word_id)->get()->toArray();

但是这个给它作为 2 维数组，如:

but this one gives it as 2 dimentional array like:

array(2) {
      [0]=>
      array(1) {
        ["word_one"]=>
        int(2)
      }
      [1]=>
      array(1) {
        ["word_one"]=>
        int(3)
      }
    }

但我想得到它:

array(2) {
    [0]=>2
    [1]=>3
}

推荐答案

您可以使用 采摘方法:

You can use the pluck method:

Word_relation::where('word_one', $word_id)->pluck('word_two')->toArray();

有关可用于集合的方法的更多信息，您可以查看 Laravel 文档.
