如何独特的价值从多维数组

Question

你好，大家好我在PHP M个新的，我有一些多维数组这样

Array 
(
    [0] => Array 
     (
      [id] => 100 
      [user_id] => 200 
     ) 

    [1] => Array 
     (

      [id] => 100 
      [user_id] => 300 
     ) 

    [2] => Array 
     (

      [id] => 100 
      [user_id] => 200 
     ) 

    [3] => Array 
     (
      [id] => 100 
      [user_id] => 400 
     ) 

    [4] => Array 
     (
      [id] => 100 
      [user_id] => 200 
     ) 

) 

我想删除像array[0]和array[2]和array[4]有重复的值。我的意思是我需要我这样的最终输出

Array 
(
    [0] => Array 
     (
      [id] => 100 
      [user_id] => 200 
     ) 

    [1] => Array 
     (

      [id] => 100 
      [user_id] => 300 
     ) 

    [2] => Array 
     (
      [id] => 100 
      [user_id] => 400 
     ) 
) 

请帮助我不知道如何在PHP中做。

使用array_unique()

array_unique($array, SORT_REGULAR);
