Subject: [PATCH] phplot.php: type casts for PHP 8.2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As announced in issue comment, I´ve just cast the arguments of the calls used for my use cases to int.

Of course, a more profound approach would be to type the respective function parameters or class properties to int or, if anyway needed, nullable int (?int), but that might break compatibility with PHP 7.x.
