It's using a feature of php called variable variable.

let's say you have a couple of variables:
$name = "fred flintstone";
$pointer = "name";

You can point to variable $name with the $pointer using the variable
variable syntax: $$pointer is evaluated as $"name", and since $pointer
contains the string "name".

echo $$pointer; // This will print "fred flintstone"

The very same mechanisms is used in the example function.
