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.
