Thumbs down problem with chapter 1

I am wending my way through chapter 1 of this book, and for the most part I am using code that was downloaded from the Wrox website, and I am still running into problems.
I couldn't get the random text generator to work properly, so I created one of my own. I found this function on the web, and it didn't work either until I played around with it a bit.
PHP Code:
// return a string of random text of a desired length
function random_text($count$rm_similar false) {
// create list of characters
$chars = array("A""B""C""D""E""F""G""H""J""K""L""M""N""P""R""S""T""U""V""W""X""Y",
// remove similar looking characters that might cause confusion
if ($rm_similar) {
$chars[0], $chars[1], $chars[2], $chars[5], $chars[8], $chars['B'], $chars['I'], $chars['O'], $chars['S'], $chars['U'],
$chars['V'], $chars['Z']);
// generate the string of random text
$text '';
  for (
$i 0$i $count$i++) {
$num mt_rand(0count($chars) - 1);           
$text .= $chars[$num];
If you wanted to you could also add lower case letters or special characters to the array to make the captcha even more complex.
