PHP 8.2 deprecated general PHP question

I notice here: https://wiki.php.net/rfc/deprecate_dollar_brace_string_interpolation

They are talking about Variable variables which I have in another custom fromework. I get a data array for the view:

        if (!empty($data)) {
            foreach ($data as $variable => $value) {
                ${$variable} = $value;
            }
            unset($variable, $value);
        }

I know laravel uses extract which does the same.

However with setting error_reporting(E_ALL); All still works fine, no deprecated warnings. I admit I don't totally understand from the link when a deprecated warning will show. And their example are using quotation marks, I have none.

Does anyone make sense if what's in the link, and is my usage of Variable variables okay?

And another link ==========================

https://www.php.net/manual/en/migration82.deprecated.php

They have this list:

• "self::method"
• "parent::method"
• "static::method"
• ["self", "method"]
• ["parent", "method"]
• ["static", "method"]
• ["Foo", "Bar::method"]
• [new Foo, "Bar::method"]

I know laravel uses static::method as do I. Again I get no deprecated warnings. I also have places with self::method. So when would these usages cause a deprecated warning.

From what I read some of the people voting was confused. -- Thanks
