PHP:-在多维数组中

我使用两个多维数组

我想删除所有删除元素的相同值，但不使用任何函数

请参见下面我的多维数组代码

<?php 

$a=array("0" => "test_3","1" => "test_4");

$b=array('test'=>array("label"=>"TEST","value"=>array(
                            "0"=>array("value"=>"test_1","label"=>"[test] Services_1"),
                            "1"=>array("value"=>"test_2","label"=>"[test] Services_2"),
                            "2"=>array("value"=>"test_3","label"=>"[test] Services_3"),
                            "3"=>array("value"=>"test_4","label"=>"[test] Services_4"),
                        )
                      ),
         'test1'=>array("label"=>"TEST","value"=>array(
                            "0"=>array("value"=>"test_11","label"=>"[test] Services_11"),
                            "1"=>array("value"=>"test_12","label"=>"[test] Services_12"),
                            "2"=>array("value"=>"test_13","label"=>"[test] Services_13"),
                            "3"=>array("value"=>"test_14","label"=>"[test] Services_14"),
                            )
                        )
        );
echo "<pre>";
print_r($a);
print_r($b);
foreach($a as $val)
  {
  $search =$val;
  $result = array_map(function ($value) use ($search) {
    //print_r($value);
    if(($key = array_search($search, $value['value'])) !== false) {
      unset($value['value'][$key]);
    }
   }, $b);
   print_r($result);
  }
echo "</pre>";
?>

在这里，我只想这样

foreach ($b as $j => $inner) {
    foreach ($inner['value'] as $k => $value) {
        if (in_array($value['value'], $a)) {      
            unset($b[$j]['value'][$k]);
        }
    }
}

请给我一个建议

您需要在数组的顶层（

$b

）使用具有正确键的unset

你的试用版中有解决问题的代码吗？是的，我为此尝试了很多代码，但我无法得到完美的结果@rokas。只需使用foreach（可能两个），然后使用if-in数组，然后取消设置Hey Ghost谢谢，我已经使用foreach-then-if和unset，检查我更新的问题，但我找不到我的真实结果。你一定是复制错了，我刚刚测试了它，它正在工作，下面是完整的代码：

Array
(
    [test] => Array
        (
            [label] => TEST
            [value] => Array
                (
                    [0] => Array
                        (
                            [value] => test_1
                            [label] => [test] Services_1

                    [1] => Array
                        (

                            [label] => [test] Services_2
                        )
                )
        )

    [test1] => Array

                        )

                    [3] => Array

                            [label] => [test] Services_14
                        )
                )
        )
)

foreach ($b as $j => $inner) {
    foreach ($inner['value'] as $k => $value) {
