Hi Kuba,
For the moment some unexpected behaviour caused by use of undefined
constant may be hard to fix with low error reporting level.
So don't use a low error reporting level.
Moreover,
treating an undefined constant as a string does not make sense. I know
that PHP is intended to be a flexible language, but for me it's a bit
thick.
Just how is PHP supposed to know that some random string is intended to be
anything else?
By the quotes :).
Undefined variable $foo doesn't fall back to string 'foo' it falls back to
null. It's a sane strategy for constants as well.
I have no information how people "rely" on this, I know the reason for this
fallback is bad syntax like: echo $hi[there];
I'd fix it in 6.0 though.
Regards, Stan Vassiev
