Hey there 🖖
I found the following comment in the docs to be true https://www.php.net/manual/en/filter.filters.flags.php#125956
The
FILTER_NULL_ON_FAILUREflag can not only be used withFILTER_VALIDATE_BOOL/FILTER_VALIDATE_BOOLEANbut also with other validating filters.This PR updates the docs accordingly, see https://3v4l.org/raIiu
Kind regards
