conversion of php

hi all i have done this captcha (text only) in php and wondered if anyone could help me turn it into coldfusion.

It could be of use to a few people

**************php*******************************
        function captcha() {
          $numbers = array("zero", "one", "two", "three",  "four", "five",  "six", "seven", "eight", "nine");
          $rand = array_rand($numbers,2);
          $result=$rand[0]+$rand[1];
          $question = "<b>".$numbers[$rand[0]]."</b> plus <b>".$numbers[$rand[1]]."</b>";
          $out .= '<label for="captcha">Please enter the result into the box below:(Answer in numbers only)<br /> '.$question.' equals</label> <input type="text" name="captcha"id="captcha">';
       $out .= '<INPUT TYPE=hidden NAME=val1 VALUE='.$numbers[$rand[0]].'>';
       $out .= '<INPUT TYPE=hidden NAME=val2 VALUE='.$numbers[$rand[1]].'>';
       $out .= '<INPUT TYPE=hidden NAME=result VALUE='.$result.'>';
          return $out;
      }
