Drop support for php 7.x #43
Description
as all php 7.x version are currently out of support. I suggest offering support only for PHP 8.x. Some progress is already made here in this PR #38. People with php7.x will still be able to use the existing psonic 2.x releases. Before providing the support only to PHP 8.x, please comment if anyone has a different opinion.
Expecting to release the new version by March 31, 2023
