Almost for sure, this function could be used instead:
http://www.php.net/manual/en/function.count-chars.php
You'll be throwing away the information about how many of each letter.
I really don't understand, though, why you are doing things the way
you describe...

How do you distinguish in:
012245128410511314
between one-digit and two-digit integers?
dissatisfaction
11111
012345678901234
0->d
1->i
2->s
3->NULL (2 is 's')
4->a
5->t
6->NULL (1 is 'i')
7->NULL (2 is 's')
8->f
9->NULL (4 is 'a')
10->c
11->NULL (5 is 't')
12->NULL (1 is 'i')
13->o
14->n
Going from just the numbers, now I get:
012245128410511314
dissatisfaidtiiNULLia
So, given the input 012245128410511314, you are never going to get the
original word back from just that...
I don't think your formula makes sense in the first place...
If you just want to represent each character as a GD image, and not
duplicate, so the browser can cache images, you can just do:
<?php
for ($i = 0, $len = strlen($word); $i < $len; $i++){
$char = $string[$i];
?><img src="drawchar.php/char=<?php echo $char?>" /><?php
}
?>
You can then use $_SYSTEM['PATH_INFO'] (or whatever it's called) to
get 'char=?' and do like:
list($key, $value) = explode('=', $_SYSTEM['PATHINFO']);
$$key = $value;

If you are using list/each or something like that, there is an
"internal pointer" in the array which you are mucking with, and most
likely confusing yourself with.
Try using 'foreach' which does not use that internal pointer.

Posting here FIRST is good, especially since you have not encountered
an actual bug yet :-)
After that, though, there *IS* a place to search for, and ultimately
report bugs:
http://bugs.php.net
But please don't clog that with reports before checking them out
thoroughly, so you really ARE reporting bugs in PHP.
