Playsms 1.4.6 (latest one) running on PHP 8.X

Hi all, I’ve upgraded Playsms 1.4.X (last release downloadable on github: GitHub - playsms/playsms at 1.4.x )

to PHP 8.X.

Tested with PHP 8.2 and PHP 8.3, on UBUNTU 22.04 and all works!!! so you can install o ubuntu 22.04 or newer, debian 11 or newer.
