In my last application, i was in need to show numbers in words. So while i was roaming arround in web got a php method here http://www.karlrixon.co.uk/writing/convert-numbers-to-words-with-php/ . Then using this method i made a cakephp helper to solve my purpose.
Step 1: Download the number_to_word.php script and keep it in app/views/helpers/
Step 2: Load this helper in the desired controller or in appcontroller.
Step 3: Now in the follwoing way you can use in your cakephp view
NumberToWord->convert_number_to_words(8769); //eight thousand,seven hundred and sixty nine ?>
