What role does the "return" value play in the form submission process in PHP?

The "return" value in the form submission process in PHP typically refers to the value returned by the form processing script after the form data has been submitted. This value can be used to determine the success or failure of the form submission and can be used to display appropriate messages to the user. 

// Form submission processing script
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data
    if ($form_data_is_valid) {
        // Successful form submission
        $return_value = "Form submitted successfully!";
    } else {
        // Failed form submission
        $return_value = "Form submission failed. Please check your inputs.";
    }
    
    // Return the value to the form page
    echo $return_value;
}
