How to replace a value in multidimensional array - PHP

Question

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

                  )

         )

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.

Don't undersatand :( Do you want chnge $data[0][form_id] to $data[0][Myform]? or make $data[0][form_id] = MyForm ? — splash58

I belive you can do that using array_walk_recursive.

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');
