T15373: PHP 8.1 "strlen(null)" exception blocks dragging a task to a workboard column

Summary

On a Workboard without any "Group by <something>", when moving a Task from a Column
to another, in PHP 8.1 there was a crash caused by a null passed to strlen().

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 T15373

Test Plan

Applied this change and afterwards dragging a Task card to another Column succeeded,
with or without a "Group by <something>" query.

Tested locally, with and without "Group By <something>"

Hoping to be useful I expand the test plan, and I add a small inline documentation

Thanks again

sgtm

src/applications/project/controller/PhabricatorProjectMoveController.php
31	✅ I verified that the above line is just null or a string The function `phutil_nonempty_string()` will report any alien type, and that is OK.

This revision is now accepted and ready to land.May 9 2023, 16:29

add minor inline documentation
