Re: [PHP] Why the Change in Ver 4?
Yea, it's true. There was a post a couple of weeks ago from Rasmus
(IIRC) that explained the reasoning: the [] form is used on strings and
arrays, so PHP has to figure out which one it's dealing with before it
can return a result. If $myAr[] and $myStr{} are seperate, the
interpretter will know instantly which one it's dealing with, and the
step can be skipped.
Also, IMO, it helps the programmer - you, too, know when you're dealing
with strings and when you're dealing with arrays, just by the indexing
operator used.

Does Version 4 support either { } "squiglees" or [ ] "brackets" in
this
code:
if($retrn{strlen($retrn)-1} == '')
-or-
if($retrn[strlen($retrn)-1] == '')
Yes. This is a 4.x feature only. The idea is that in the long run,
[]
will no longer be supported for string offsets, only {} will.
What is the motivation behind this change?
