Although our package follows simple standards and we mostly make use of simple PHP features, we decided to only support PHP 8.1 and above.
The reason for this choice is that at the time of this writing (2022-11-11), PHP 7.4 is no longer maintained and PHP 8.0 is 2 weeks away from the end of active support.
We are aware that this decision may exclude some users from using our package, but we believe that the benefits of using PHP 8.1 outweigh the disadvantages.
We also advocate that every new PHP application should be written in the latest version of the language whenever possible.
