如何从多维数组中删除数组? [英] how to remove an array from a multidimensional array?

问题描述

我有一个多维的，它是一个动态数组，如:

I have a multidimensional which is a dynamic array like :

Array
(
    [0] => Array
        (
            [key] => delete
            [label] => hi Delete
        )

    [1] => Array
        (
            [key] => edit
            [label] => hi Edit
        )

    [2] => Array
        (
            [key] => update
            [label] => hi update
        )

)

现在我想从上面的多维数组中删除下面的一个数组:

now i want to delete an array below from above multidimensional array:

Array
    (
        [key] => delete
        [label] => hi Delete
    )

最后我想要一个输出:

数组(

    [0] => Array
        (
            [key] => edit
            [label] => hi Edit
        )

    [1] => Array
        (
            [key] => update
            [label] => hi update
        )

)

为此我已经尝试过，下面是我的代码:

For this i have tried, below is my code:

<?php
  $arr1 = array(array("key" => "delete", "label" => "hi Delete"),array("key" => "edit", "label" => "hi Edit"), array("key" => "update", "label" => "hi update"));
   $diff = array_diff_assoc($arr1, array("key" => "delete", "label" => "hi Delete"));
   print_r($diff);
?>

但是我在输出中得到了完整的 $arr1:

But i get full $arr1 in the output:

Array
(
    [0] => Array
        (
            [key] => delete
            [label] => hi Delete
        )

    [1] => Array
        (
            [key] => edit
            [label] => hi Edit
        )

    [2] => Array
        (
            [key] => update
            [label] => hi update
        )

)

我该怎么做，请帮帮我

推荐答案

使用 array_filter with callback as

$arr1 = array_filter($arr1, function ($var) {
    return $var['key'] != 'delete';
});
print_r($arr1);
