Variable in array key

Question

Have array $data with keys like checkout_en, checkout_ru and have var $lang with two variants ru and en.

How can i make smht like this $data['checkout_$lang'] to make key checkout_en or checkout_ru depends on $lang var value.

Thank you!

my code

$msg = '"buttons": [
            {
              "block_names": ["'.$settings['checkout_block_name'].'"],
              "type":"show_block",
              "title":"'.$settings["checkout_$settings['user_lang']"].'"
            }';

Or `$data["checkout_$lang"]` Note use of double quotes, not single as you have in the question. — Nick, Aug 08 '18 at 05:58
$data['checkout_'.$lang] @ZainFarooq you need to remove last quote — Parth Shah, Aug 08 '18 at 05:58

Solution in my case:

   {
     "block_names": ["$settings[start_block_name]"],
     "type":"show_block",
     "title":"'.$settings["back_to_shop_$settings[user_lang]"].'"
    }

Thanx:)
