Php 从嵌套数组中删除重复的值

我正在让堆栈删除重复的键，并将它们分配给一个新数组

我的阵列：

  array     (
            [1] => Array
                (
                    [name] => name1
                    [actions] => add
                )

            [2] => Array
                (
                    [name] => name1
                    [actions] => remove
                )

            [3] => Array
                (
                    [name] => name2
                    [actions] => dosomething1
                )
            [4] => Array
                (
                    [name] => name2
                    [actions] => dosomething1
                )

        )

 array    (
                [1] => Array
                    (
                        [name] => name1
                        [actions] => add
                        [actions] => remove
                    )         
                [2] => Array
                    (
                        [name] => name2
                        [actions] => dosomething1
                        [actions] => dosomething1
                    ) 

            )

我正在努力实现的目标：

  array     (
            [1] => Array
                (
                    [name] => name1
                    [actions] => add
                )

            [2] => Array
                (
                    [name] => name1
                    [actions] => remove
                )

            [3] => Array
                (
                    [name] => name2
                    [actions] => dosomething1
                )
            [4] => Array
                (
                    [name] => name2
                    [actions] => dosomething1
                )

        )

 array    (
                [1] => Array
                    (
                        [name] => name1
                        [actions] => add
                        [actions] => remove
                    )         
                [2] => Array
                    (
                        [name] => name2
                        [actions] => dosomething1
                        [actions] => dosomething1
                    ) 

            )

我尝试过的：

    public function array_unique_multidimensional($input)
{
    $serialized = array_map('serialize', $input);
    $unique = array_unique($serialized);
    return array_intersect_key($input, $unique);
}

它错误地返回了相同的数组。任何帮助都将不胜感激。

您不能有两个带有保存值的数组键（所以对于给定元素不可能有两个actions元素），您可以做的是有一个包含多个值的action元素

  $results = array();
  foreach ($array as $v){
      if (!isset($results[$v["name"]]){
           $results[$v["name"]] = array("name"=>$v["name"], "actions"=>array($v["actions"]));
      } else {
          $results[$v["name"]]["actions"][] = $v["actions"];
      }
  }

如果要删除顶级数组上的字符串键，则可以执行以下操作

 $results = array_values($results);
