What does the "responseText" property in AJAX return when submitting form data to PHP?

When submitting form data to PHP using AJAX, the "responseText" property typically returns the response from the PHP script. This response can be any data that the PHP script outputs, such as a success message, error message, or any other content. 

<?php
// Handle form data submission
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data
    $name = $_POST["name"];
    $email = $_POST["email"];
    
    // Perform any necessary validation or processing
    
    // Return a response
    echo "Form data submitted successfully!";
}
?>
