A question about null coalescing operator..

$this->request->data['comments']['user_id'] = $this->request->data['comments']['user_id'] ?? ‘value’;

I want to check if some var is null and if the same var is null set the same var to ‘value’.

Hence I am repeating the same variable after the equal operator, this does not feels right.

So I feel that we need another operator like “??=“ similar to +=;

$this->request->data['comments']['user_id’] ??= ‘value’. So if the var is null it’s set to ‘value’ and else stays the same.
