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 T15312 Test Plan: Applied this change (on top of D25144, D25145, D25146, D25147, D25151, D25152, D25153 and `/project/query/active/` rendered correctly in web browser. Tested surfing various pages with and without Maniphest's `maniphest.subtypes`. If you need some example custom fields, this is an example: ``` [ { "key": "default", "name": "Task" }, { "key": "bug", "name": "Bug" }, { "key": "log", "name": "LogSpam" }, { "key": "deadline", "name": "Deadline" } ] ``` Reviewers: O1 Blessed Committers, valerio.bozzolan Reviewed By: O1 Blessed Committers, valerio.bozzolan Subscribers: speck, tobiaswiese, valerio.bozzolan, Matthew, Cigaryno Maniphest Tasks: T15312 Differential Revision: https://we.phorge.it/D25162
