How can a PHP variable be incremented by clicking a link?

To increment a PHP variable by clicking a link, you can use a combination of HTML and PHP. You can create a link that sends a request to the server when clicked, and in the PHP code, you can increment the variable value. You can achieve this by passing the current variable value as a query parameter in the link URL, then incrementing it in the PHP code that handles the request. 

<?php
$counter = isset($_GET['counter']) ? $_GET['counter'] : 0;

if(isset($_GET['increment'])){
    $counter++;
}

echo "Counter: " . $counter;
?>

<a href="?counter=<?php echo $counter ?>&increment=true">Increment Counter</a>
