It seems when typecasting is used, offsetExists is never called. It doesn't matter whether I try to typecast to string or int. Test script: --------------- <?php $data = new class implements \ArrayAccess { public function offsetExists($offset) { echo "offsetExists\n"; } public function offsetGet($offset) { echo "offsetGet\n"; } public function offsetSet($offset, $value) { } public function offsetUnset($offset) { } }; echo "null coalescing operator:\n"; $data['foo'] ?? null; echo "null coalescing operator (typecast):\n"; (int)$data['foo'] ?? null; Expected result: ---------------- null coalescing operator: offsetExists null coalescing operator (typecast): offsetExists Actual result: -------------- null coalescing operator: offsetExists null coalescing operator (typecast): offsetGet ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77681&edit=1
