Hello Nathan,
Do you mean $x{8}?
That is good but not for all situations.
I need sometimes to make an array with letters as keys and numbers as
values, like this (I give English alphabet just as an example, so
please don't suggest str_split):
$alphabet="abcdefghijklmnopqrstuvwxyz";
// I wish that worked
$alphabet_array=explode('', $alphabet);
$letter_numbers=array_flip($alphabet_array);
this is just one case I encountered some time ago. Yes, I made this by
separating letters with commas... but it's not the unique case when I
need it.

Strings are already accessible through array notation anyway, seems like ol
dude may benefit from a php-general membership as well.

yup, that or $x[8];

this just looks like you're after a quick way to populate an array.

do you remember what you needed it for? w/ the array access notation you
can get at any letter by index or you can get any index by letter.
$alphabet="abcdefghijklmnopqrstuvwxyz";
echo $alphabet[1]; // b
echo strpos($alphabet, 'b'); // 1

It would be nice to hear what the use-case is for this issue.

Well the argument has both sides. Division by zero on many platforms resulted
in zero. Then came IBM360 and it generated an exception causing big time issues
in legacy code so a OS patch was written to intercept the interrupt, jam the
result to zero and return.
Although mathematically undefined is correct, in most programtic cases zero is
an acceptable and in fact a preferred result.

first off quercus is not 'the' implementation of php running on the jvm,
it's 'an' implementation. ibm project 0 is another
http://www.projectzero.org/
and there may be more. also, java is fast, but php applications can be made
fast as well, when it comes to serving web pages. there are times when i
would consider implementing some domain logic in something like java for
speed, but for delivering applications on the web, php is very useful and
practical in terms of performance.

a lot of projects are mating their favorite language w/ the jvm which does
seem like a great idea, but one of the main drawbacks is the pace of feature
additions w/ the 'real' version of the project. when i looked into quercus
a few years ago there wasn't support for things like spl and i'm not sure
where they stand w/ 5.3 features like closures and namespaces. not only that
but on any given minor release of php where is the parallel from quercus.
also, the professional version of resin costs money.
these are probly the main reasons why the resin community isn't blowing up.

I refer back to my comment that the "Sent from my iPad/iPhone" is
inherently an apology.
