Question

I know this seems like something that should be averted by design, but let’s just say it is bitterly needed:
Is it possible to reference the key belonging to a value while it is being initialized?

Here is what I imagine it to be (not exactly the case in which I need it, but the key is primitive as well):

$array = array(25 => "My key is " . $this->key);

I need this because the array key is used in each value. Actually the value is another array which has a value in which the first array key is used. Like I said in the comments, I want to keep it DRY. Doing it is no problem, but I want to do it good 😉

Answer 1

No, there is no way to reference the key when defining the value. Except maybe writing a preprocessor that embeds it in the string. But that would only work for primitive values.
