Bug #78508 [NEW]: PHP does not emit a warning when some types are accessed with an index

From: michael dot vorisek at email dot cz Operating system: Linux PHP version: 7.3.9 Package: *General Issues Bug Type: Bug Bug description:PHP does not emit a warning when some types are accessed with an index Description: ------------ I found out that current PHP does not emit warnings at least for the following expressions: a) if boolean is accessed with index: false['x'] b) if null is accessed with index: null['x'] in contrary with string type, which emits the following message: Warning: Illegal string offset 'x'... Notice: Uninitialized string offset: 0 I would expect PHP to emit at least Notice warning. Is this a bug which needs to be addressed or is this an intended behaviour for some use case/backcompatibility that requires no warning?
