How can JavaScript and PHP be effectively integrated to handle multiple form submissions on a single page without causing data duplication?

When handling multiple form submissions on a single page using JavaScript and PHP, it is important to prevent data duplication by ensuring that each form submission is processed separately. One way to achieve this is by assigning a unique identifier to each form submission and using this identifier to track and process the data accordingly in the PHP backend. 

<?php
// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Generate a unique identifier for the form submission
    $unique_id = uniqid();

    // Process form data based on the unique identifier
    if (isset($_POST['form1_submit'])) {
        // Process form 1 data
        // Use $unique_id to track form 1 submission
    }

    if (isset($_POST['form2_submit'])) {
        // Process form 2 data
        // Use $unique_id to track form 2 submission
    }

    // Repeat for additional forms as needed
}
?>
