Are there any best practices for implementing click protection in PHP without using Java?

Implementing click protection in PHP without using Java can be achieved by utilizing session variables to track the user's activity and prevent multiple clicks on a button or link. One approach is to set a session variable upon clicking the button and check if it has been set before allowing the action to be performed. This helps prevent duplicate form submissions or unintended actions caused by multiple clicks. 

session_start();

if(isset($_POST['submit'])) {
    if(!isset($_SESSION['clicked'])) {
        // Perform action here
        $_SESSION['clicked'] = true;
    } else {
        // Display error message or redirect to prevent multiple clicks
        echo "Button has already been clicked.";
    }
}
