Problem
SplDoublyLinkedList::{offsetGet,offsetUnset,offsetExists}(null) under non-strict types must emit E_DEPRECATED for parameter #1 ($index) and soft-coerce to 0. Today:
offsetGet / offsetUnset → TypeErroroffsetExists → silent true (no DEP)
offsetSet(null) remains append-without-DEP (#31731).
Probed 2026-08-17 — host Zend PHP 8.2+ vs php bin/vm.php.
