What are the advantages and disadvantages of using HTML forms with PHP for data submission?

When using HTML forms with PHP for data submission, one advantage is that it allows for user input to be easily collected and processed by the server-side script. This enables dynamic and interactive websites. However, a disadvantage is that it may be prone to security vulnerabilities such as cross-site scripting (XSS) attacks if proper input validation and sanitization measures are not implemented. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $input_data = $_POST['input_field'];
    
    // Validate and sanitize input data
    $sanitized_data = htmlspecialchars(strip_tags(trim($input_data)));
    
    // Process the sanitized data
    // ...
}
?>
