如何替换多维数组中的值-PHP [英] How to replace a value in multidimensional array - PHP

问题描述

我有一个多维数组，需要替换其中的键(form_id)值.

I have a multidimensional array and I need to replace a value of a key (form_id) in it.

 $data = Array
    (
            [0] => Array
                  (
                    [product_id] => 1
                    [form_id] => 18
                    [product_name] => test tet

                  )

            [1] => Array
                  (
                    [product_id] => 2
                    [form_id] => 18
                    [product_name] => test product

                  )

         )

将" form_id "替换为值"我的表单"之后，我需要返回整个多维数组.请给我一个解决方案，谢谢.

after replacing the "form_id" with value "My Form" then i need to return the whole multidimensional array. Please give me a solution, thanks in advance.

推荐答案

我相信您可以使用这是一个(未经测试的)示例:

Here's an (untested )example :

 $data = Array
    (
            [0] => Array
                  (
                    [product_id] => 1
                    [form_id] => 18
                    [product_name] => test tet

                  )

            [1] => Array
                  (
                    [product_id] => 2
                    [form_id] => 18
                    [product_name] => test product

                  )

         )
function array_replacing(&$item, $key)
{
    if($key == 'form_id')
        $item = 'myform';
}

array_walk_recursive($data, 'array_replacing');
