While working on migrating the codebase to PHP 8, I noticed that a rule (
NullToStrictStringFuncCallArgRector
) often triggered that consists in adding casts to string, because internal functions have become more strict in PHP 8.1 (they no longer accept anything than a string).I tried finding why those arguments were not considered already strings, and tried to fix some of that with this PR.
