Mission complete, was able to update all of my library code to PHP 8.0. Not to soon and 8.1 will be out, but at least I can work on upgrading the Apps to use PHP 8.0. Once that happens it will be easier to update to PHP 8.1. In the process there are few new things I am trying out. Added a couple newish tools to my PHP code checks. The first is PHP Metric, which is a lot like PDepend with more data. It also has a violations page which helps pick out packages that are not living up to standards and gives you some general reasons why.
