This function breaks a piece of text into characters and shows them on a newline. I could not for the love of me get the \n to work so I added <br /> instead.
$sLen = strlen($string); // length in numbers of the text
$i = 0; // iteration start point
$characters = "";
for($i = 0; $i < $sLen; $i++) // iterate from 0 to length of the string
$characters .= $string[$i]. "<br />"; // store each character as a space seperated array.
return $characters; // return the list of the characters
