Summary

strlen() was used in Phabricator to check if a generic value is a non-empty string.
This behavior is deprecated since PHP 8.1. Phorge adopts phutil_nonempty_string() as a replacement.

Note: this may highlight other absurd input values that might be worth correcting
instead of just ignoring. If phutil_nonempty_string() throws an exception in your
instance, report it to Phorge to evaluate and fix that specific corner case.

Closes T15383

Event Timeline

Thanks for this patch (again)!

Believe me or not but I tested this intensively, following the test plan. If you don't believe me:

I hope this will not explode in the future like a nuclear bomb as we usually see then.
