How can HTML validation errors impact the functionality of a PHP form?

HTML validation errors can impact the functionality of a PHP form because they can prevent the form from submitting properly or cause unexpected behavior when processing the form data. To solve this issue, ensure that the HTML code is valid by using a validator tool to check for errors and correct them. This will help ensure that the form functions as intended and submits the data correctly to the PHP script for processing. 

<?php
// PHP code for processing form data
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data here
}
?>
