                  问题描述

                  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.

                  For more info on what methods are available for using with collection, you can you can check out the Laravel Documentation.
