How can sessions be utilized effectively in PHP for implementing a counter on a website?

To implement a counter on a website using sessions in PHP, you can store the counter value in a session variable. Each time the page is loaded, you can increment the counter value stored in the session. This way, the counter will persist across different page loads for the same user. 

session_start();

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

echo "You have visited this page " . $_SESSION['counter'] . " times.";
