Bug description: Accessing string offsets (array notation)
Description:
------------
While messing around with the feature mentioned in the summary, I came
across some undocumented results and/or bugs which should be documented (or
fixed respectively).
Offsets
- When using an out of range offset, the string is padded with spaces.
- When using a floating point number as offset, it is *always* rounded
down.
- When using an illegal type (such as an array) as offset, a warning is
emitted and 0 is assumed.
- When using a negative offset, PHP reports an uninitialized offset in
read context, but reports an illegal offset in write context.
Insert strings
- When using a string which length is greater than 1, only the first
character is used. (Fairly obvious but not documented)
- When using a string which length is 0 ("", that is), a \0 character is
inserted at that position instead.
The last result is the strangest one. Might be a bug.
