Subject: Re: [PHP-DEV] Array key access on non-array values - to be made
 illegal?
From: ivan.enderlin@hoa-project.net (Ivan Enderlin)

Hello Marco,

Actually, you are trying to access to something that does not exist, so 
you get a null value. This part is logical. However, yes, a notice would 
be welcomed except it may be skipped for historical reasons I reckon. 
Probably to work well with `isset` or similar scenario.

Cheers.
