How to use a variable variable in an array walk?

[Nils Leideck <nils.leideck@xxxxxxxxxx>]

Dear list,

this is my first post to the PHP general list.

I have an issue with a variable variable (http://php.net/manual/en/language.variables.variable.php)

My use case:

I have an array called $myArray. The structure is as following:

array(1) {
  ["user_interface"]=>
  array(1) {
    ["design"]=>
    array(1) {
      [“my_colors"]=>
      array(5) {
        ["item_number_one"]=>
        string(6) "red"
        ["item_number_two"]=>
        string(40) '["user_interface"]["design"]["my_colors"]["item_number_one"]'
     }
    }
  }
}

As you can see, the item_number_one has no direct color value assigned but the structure of the path to item_number_one in the $myArray variable. I tried with array_wal_resursive. During this step (the array building is completed) I want to find these values (I use a static value in my example, in the real code I will use regular expressions) and assign the value of the virtually related item to the considered item.

So in my example above, I want to have the following values after the process is done:

$myArray[user_interface][design][my_colors][item_mumber_one] = red; // this is item number 1
$myArray[user_interface][design][my_colors][item_mumber_two] = red; // this should be item number 2

The second issue here is, how do I evaluate at which point the process is exactly, because the value and the key that is transferred to the function by array_walk_recursive has only the value itself but not array path to the current item.

Any idea how get this done? Or am I too complicated maybe?

I tried several combinations of ${$var}, $myArray{$var}, {$myArray}{$var} ... and many more.

Any help is much much appreciated!


Merry X-mas greeting from Indianapolis

Cheers, Nils
