How can improper HTML syntax affect the functionality of PHP scripts, specifically in form processing?

Improper HTML syntax can affect the functionality of PHP scripts, particularly in form processing, by causing errors in the way data is passed from the form to the PHP script. This can result in undefined variables, incorrect data types, or other issues that prevent the script from processing the form data correctly. To solve this issue, ensure that the HTML form elements have proper syntax, including correct attribute values and closing tags.

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    // Process the form data
}
?>
