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_scalar() as a replacement when both string and integers could be passed as a value like here.
Note: this may highlight other absurd input values that might be worth correcting
instead of just ignoring. If phutil_nonempty_scalar() throws an exception in your
instance, report it to Phorge to evaluate and fix that specific corner case.
Also fix similar warning for ctype_digit(): Argument of type null will be interpreted as string in the future by checking for null first.
