Sounds like a good idea - available open source static analyzers are much better than they were when php 7.0.0 was released, and php now has nullable types, union types and property types. E.g. Phan already warns about passing null/nullable to internal functions as strictly as user-defined functions, partly because I'd assumed internal functions would change in the future. https://phan.github.io/demo/?code=%3C%3Fphp%0Afunction+test%28%3Fstring+%24str%29+%7B%0A++++return+strlen%28%24str%29+%2B+strlen%28null%29%3B%0A%7D (10MB webassembly demo) Regards, Tyson -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php
