Capital Letters Counter in PHP

In this article I would like to share with you a sample program that enables the user to count the number of capital letters in a given word or sentence by our user. I wrote a function called count_capital_letters to count the occurrence of capital letters in a given word or sentence. I hope you will find my work useful in your programming assignments or projects in PHP.

 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
