While you are correct that invalid offset in a string will produce an
error message. This error message is E_NOTICE, given that our default
INI error reporting level won't display those it's arguable that very
few people will see them and consequently do something about it.

echo $a{strlen($a)-1}; ? is that really that bad.
I do worry that at present
$a = "a string";
$p = 0
while( $p < strlen($p) )
.. do stuff that could do $p-- or $p++
echo $a{$p};
}
at present that would produce a nice error if you went < 0.. easy to
spot.. - if -ve was supported it could d

Yeah, [] is for arrays, {} for string indexes though I still think this
should not be in, one can use substring for this. Something like a
"negative string index" is IMO too much magic.

Sure, I have no operator preference.

Right, I was about to say that too. If we only did it for the {} operator
it would encourage people to use that little-used operator thereby
removing a source of confusion and at the same time the BC issues are
minimal.

I am wondering what are people's opinions on adding support for negative
string offsets that could be used to access data from the end of a string.
Ex. $a = "123"; echo $a[-1]; // would print 3
I don't think we should do this for arrays, since -1 and similar are
valid array keys, which means add
13 matches
