Number To Words Converter in PHP



   This program will ask the user to enter a number and then converts the given number into its words format in PHP. I also included a code that will check if the text field is empty and will inform the user to enter a number so that it can be convert into words.


 If you have some questions please send me an email at jakerpomperada@yahoo.com and jakerpomperada@gmail.com. People here in the Philippines who wish to contact me can reach me at my mobile number 09173084360



Thank you very much and Happy Productive Programming.
