How can a PHP script increment a variable by 1 each time it is included?

To increment a variable by 1 each time a PHP script is included, you can use a session variable to keep track of the count. Each time the script is included, you can increment the session variable by 1. This way, the variable will persist across script executions. 

<?php
session_start();

if (!isset($_SESSION['count'])) {
    $_SESSION['count'] = 1;
} else {
    $_SESSION['count']++;
}

echo "This script has been included ".$_SESSION['count']." times.";
?>
