PHP Line with 16 code output as emoji unicode?

Question

PHP

Good afternoon.
I've been scratching my head for days, rummaged through all the documentation, I can't find an answer.

There is a line in which the hexadecimal code is written.
And you need to use the variable to display it as emoji unicode

Here is the code:

$text = '1f9d2';
//Вот так смайл выводится:
echo "\u{1f9d2}";

//А через переменную не работает:
echo "\u{'$text'}"

And all my string conversions don't help.
