I made this change back in December. I guess I could revert back but I think it makes sense to be strict here. What does the rest think? Andi At 03:49 AM 4/27/2004 +0000, Curt Zirzow wrote:
I can't seem to find any discussion on this BC issue, so forgive me if this has already been discussed. Given the following; $a = 'a string'; /* E_ERROR Cannot use string offset as an array */ echo is_array($a['bar']['baz']); /* non error resolution */ echo isset($a['bar']['baz']) && is_array($a['bar']['baz']); I'm not sure, but the patch below does seem to make the E_ERROR get demoted to a E_WARNING, thus fixing it so execution simply doesn't stop when a string is referenced improperly. Or is it a *must* that php needs to stop in this case?
