What are common issues with rapid clicking in PHP applications?

Common issues with rapid clicking in PHP applications include duplicate form submissions, multiple database inserts, and unnecessary server load. To prevent this, you can use techniques like disabling the submit button after the first click or implementing a token system to ensure that each form submission is unique. 

// Disable submit button after the first click
if(isset($_POST['submit'])){
    // Process form submission
    // Add code to handle form data
    
    // Disable submit button
    echo '<script>document.getElementById("submit").disabled = true;</script>';
}
