[Resolved] Need help splitting a string

[tflight]

I need some help splitting a string. The string is composed of letters and numbers. I would like them to be split, grouping substrings of numbers together and substrings of letters together. For example, take the following string:

QW45TDS83AGH8388IWAD92C

And I'd like to split it up into an like this:

QW,45,TDS,83,AGH,8388,IWAD,92,C

My head is spinning trying to come up with a way to do this. If anyone could help I'd appreciate it. Thanks! -Tim

I dont ahve time to writ ethe whole code for you, but its something to do with ASCII Character numbers, you check each letter/number and see if it is < or > a specified value which means either letters or number and you put them all into an array

Or, if the order is not important:
eregi($string, "([0-9]+)", $numbers); print_r($numbers);
eregi($string, "([A-Z]+)", $chars); print_r($chars);

Eh, been a bad day. At least I'm semi-profienct at this. Be glad you caught me on a bad day. I rarely just write code :p

<?php
$string = 'QW45TDS83AGH8388IWAD92C'; // string to check
function checktype($char) {
   if(ctype_alpha($char)) { return "alp"; } // is alpha
   if(ctype_digit($char)) { return "num"; } // is numeric
}
$new      = array(); // place to hold chunks
$hold     = $string{0}; // current char
$holdtype = checktype($hold); // current type
for($i=1;$i<strlen($string);$i++) {
   if(checktype($string{$i}) == $holdtype) {
      $hold .= $string{$i}; // add to current string
   }
   else {
      $new[]    = $hold;
      $hold     = $string{$i};
      $holdtype = checktype($string{$i});
   }
}
echo implode(", ", $new); // comma delimit string
?>

Thanks to everyone, that will work!

LordShryku:
Would my way have worked? Im just getting back into php again, so I might abe a bit rusty, please correct my algorithim if I am wrong.
Thanks!
