What are the potential pitfalls of using JavaScript to handle arrays in PHP forms for table data?

Using JavaScript to handle arrays in PHP forms for table data can lead to potential security vulnerabilities, as client-side code can be manipulated by users. To ensure data integrity and security, it is recommended to handle array manipulation on the server-side using PHP. This can be achieved by submitting form data to the server and processing it using PHP before displaying the table data. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data
    $tableData = $_POST['tableData'];
    
    // Loop through array and perform necessary operations
    foreach($tableData as $data) {
        // Process each row of data
    }
    
    // Display table data
    // Example: echo "<table><tr><td>".$tableData[0]."</td></tr></table>";
}
?>
