php - 如何在 PHP 的以下场景中将数组元素从关联数组中移一个？

Question

我关注的关联数组标题$_POST如下：

Array
(
    [op] => add
    [product_id] => 12
    [pack] => Array
        (
            [1] => 1
        )
    [applicable_states] => Array
        (
            [0] => multiselect-all
            [1] => 1
            [2] => 2
            [3] => 3
            [4] => 4
            [5] => 5
            [6] => 6
            [7] => 7
            [8] => 8
            [9] => 9
            [10] => 10            
        )

    [total_count] => 3000
)

现在您可以观察数组中的第一个键$_POST['applicable_states']it's [0] => multiselect-all。我必须在操作数组之前检查这个键。每当此键出现在数组中时，我都需要如下$_POST数组：

Array
(
    [op] => add
    [product_id] => 12
    [pack] => Array
        (
            [1] => 1
        )
    [applicable_states] => Array
        (
            [0] => 1
            [1] => 2
            [2] => 3
            [3] => 4
            [4] => 5
            [5] => 6
            [6] => 7
            [7] => 8
            [8] => 9
            [9] => 10            
        )

    [total_count] => 3000
)

现在您可以从上面的数组中看到 已从[0] => multiselect-all新的结果数组中删除，并且每个数组值都将其位置更改为 1。我应该如何以最佳方式将我的$_POST数组转换为上述结果数组？提前致谢。

Answer 1

if (array_search('multiselect-all', $_POST['applicable_states']) === 0) 
    array_shift($_POST['applicable_states']);
