Lowercase and Digits Counter in PHP

In this article I would like to share a program that I wrote that will allows the user to count the number of occurrence of lowercase letters and digits in a given sentence using PHP as our programming language. What does the program will do is to ask the user to enter a word or a sentence and then our program will count how many times the lowercase letters and digits occurs in a given word or sentence.

If you have some questions please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com. My mobile number here in the Philippines is 09173084360.


Thank you very much and God Bless.
