I am searching for a way to check my PHP code for compatibility with different PHP versions. Especially compatibility to PHP version 7.2 - 8.1 is what I am looking for. At first I tried phpcs but the results were not really good, so I tried something different.
To test the code I introduced phpstan which works really well (for one PHP version) but it seems it is only possible to specify one PHP version per configuration.
My phpstan.neon file:
parameters:
level: 0
phpVersion: 70400
paths:
- src/project
- src/library
Running vendor/bin/phpstan -c phpstan.neon works as expected.
Tried to specify more than one value for phpVersion but this only produces an error because the argument has to be int|null value.
Does anyone know a method to check more than one PHP vesion in just one run of phpstan? Maybe there is an appropriate rule set for different PHP versions?
