How can the Content-Type of the response header impact the behavior of a PHP form submission?

The Content-Type of the response header can impact the behavior of a PHP form submission by specifying the type of data being returned. If the Content-Type is not set correctly, the browser may not interpret the response correctly, leading to unexpected behavior. To ensure proper handling of form submissions, set the Content-Type header to "application/json" when returning JSON data from a PHP script. 

<?php
header('Content-Type: application/json');
// Process form submission
echo json_encode($response);
?>
