Question

我想要修改一个标题为$rebate_by_prod的数组。数组内容如下：

Array
(
    [op] => preview
    [id] => 280
    [form_submitted] => yes
    [rebate_id] => 280
    [main_op] => edit
    [site_url] => http://localhost/smart-rebate-web/web/
    [rebate_image_url] => http://localhost/smart-rebate-web/web/images/rebates/rebate_images_by_product/2014/rebate_1412690625.gif
    [image_path] => rebates/rebate_images_by_product/2014/rebate_1412690625.gif
    [brand_id] => 134
    [1] => Array
        (
            [product_id_1] => Array
                (
                    [0] => 214
                    [1] => 215
                    [2] => 216
                )

            [pack] => 1
            [quantity] => 1
            [units] => 51
            [amount] => 3.0
        )

    [2] => Array
        (
            [pack] => 1
            [quantity] => 2
            [units] => 49
            [amount] => 10.0
            [product_id_2] => Array
                (
                    [0] => 214
                    [1] => 215
                    [2] => 216
                )

        )

    [title] => Three Olives Vodka
    [rebate_start_date] => 
    [rebate_expiry_date] => 2014-10-31
    [applicable_states] => Array
        (
            [0] => 30
        )

    [multiselect] => 30
    [rebate_total_count] => 150
    [details] => Three Olives
)

现在我已经编写了一个函数，它在做了一些必要的修改之后生成了以下输出数组：功能如下：

 function change_product_keys($reb_by_product) {
          foreach ($reb_by_product as $index => $sub) {
            if (is_array($sub)) {
              foreach ($sub as $key => $value) {
                if (strpos($key, 'product_id_') !== FALSE) {
                  $reb_by_product[$index]['products'] = $value;
                  unset($reb_by_product[$index][$key]);
                }
              }
            }
          }
          return $reb_by_product;      
        }

标题为$reb_by_product的输出结果数组如下：

Array
(
    [op] => preview
    [id] => 280
    [form_submitted] => yes
    [rebate_id] => 280
    [main_op] => edit
    [site_url] => http://localhost/smart-rebate-web/web/
    [rebate_image_url] => http://localhost/smart-rebate-web/web/images/rebates/rebate_images_by_product/2014/rebate_1412690625.gif
    [image_path] => rebates/rebate_images_by_product/2014/rebate_1412690625.gif
    [brand_id] => 134
    [1] => Array
        (
            [pack] => 1
            [quantity] => 1
            [units] => 51
            [amount] => 3.0
            [products] => Array
                (
                    [0] => 214
                    [1] => 215
                    [2] => 216
                )

        )

    [2] => Array
        (
            [pack] => 1
            [quantity] => 2
            [units] => 49
            [amount] => 10.0
            [products] => Array
                (
                    [0] => 214
                    [1] => 215
                    [2] => 216
                )

        )

    [title] => Three Olives Vodka
    [rebate_start_date] => 
    [rebate_expiry_date] => 2014-10-31
    [applicable_states] => Array
        (
            [0] => 30
        )

    [multiselect] => 30
    [rebate_total_count] => 150
    [details] => Three Olives
)

其实我想要操作数组如下：

Array
(
    [op] => preview
    [id] => 280
    [form_submitted] => yes
    [rebate_id] => 280
    [main_op] => edit
    [site_url] => http://localhost/smart-rebate-web/web/
    [rebate_image_url] => http://localhost/smart-rebate-web/web/images/rebates/rebate_images_by_product/2014/rebate_1412690625.gif
    [image_path] => rebates/rebate_images_by_product/2014/rebate_1412690625.gif
    [brand_id] => 134
    [1] => Array
        (
            [pack] => 1
            [quantity] => 1
            [size_id] => 51
            [amount] => 3.0
            [products] => Array
                (
                    [0] => 214
                    [1] => 215
                    [2] => 216
                )

        )

    [2] => Array
        (
            [pack] => 1
            [quantity] => 2
            [size_id] => 49
            [amount] => 10.0
            [products] => Array
                (
                    [0] => 214
                    [1] => 215
                    [2] => 216
                )

        )

    [title] => Three Olives Vodka
    [rebate_start_date] => 
    [rebate_expiry_date] => 2014-10-31
    [applicable_states] => Array
        (
            [0] => 30
        )

    [multiselect] => 30
    [rebate_total_count] => 150
    [details] => Three Olives
)

我希望每个内部数组的[units]键都更改为[size_id]。我为实现这个目的而编写的当前函数需要做些什么改变？提前谢谢。

            function change_product_keys($reb_by_product) {
                 $reb_by_product_copy = $reb_by_product;
                      foreach ($reb_by_product_copy as $index => $sub) {
                        if (is_array($sub)) {
                          foreach ($sub as $key => $value) {
                            if (strpos($key, 'product_id_') !== FALSE) {
                              $reb_by_product[$index]['products'] = $value;
                              unset($reb_by_product[$index][$key]);
    ###############################
                              $reb_by_product[$index]['size_id'] = $reb_by_product[$index]['units'];
                              unset($reb_by_product[$index]['units']);
    ################################
                            }
                          }
                        }
                      }
                      return $reb_by_product;      
                    }

使用函数输出作为工作数组

如何在以下函数代码中从内部数组更改数组键的值？
