Question

Let’s say I have a variable $day. It can be anything from Monday to Sunday. How could I use that $day variable and increment it by 1 day?

Let’s say, I have $day = "Friday". How do I increment it to a Saturday?

Answer 1

Use date() and strtotime() adding ‘+1 day’ to your string:

<?php
$day = "friday";
$day = date('D',strtotime($day.'+1 day'));
echo $day; // "Saturday"
?>
