PHP Age Calculator Source Code

To complete this program with debugging free code you have to create only one file(index.php) because we use the bootstrap framework to style our CSS. And we also post data on the same page using the PHP function "isset($_POST['submit']))" that only show data ones it’s submitted.

Next, Here we two types of date “Date of Birth” and “Age at the Date of “. When you select both the date and submit for the result then the PHP function will execute and display the result of your selected date of birth. It’s predominantly used DateTime() and date diff() function. DateTime() function used to set date in DateTime format and diff() function used for differentiating between two dates.

Back to coding,

index.php

Create a PHP file named ‘index.php‘ and put those codes given below.
