Are there specific PHP functions or methods that can streamline the process of handling form data initialization?

When handling form data initialization in PHP, it is helpful to use the `$_POST` superglobal array to retrieve and store form data submitted via POST method. By using PHP functions like `isset()` and `filter_input()` along with methods like `htmlspecialchars()` and `trim()`, you can ensure that the form data is properly initialized and sanitized before processing it further. 

// Initialize form data variables
$name = '';
$email = '';
$message = '';

// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Retrieve and sanitize form data
    $name = isset($_POST['name']) ? htmlspecialchars(trim($_POST['name'])) : '';
    $email = isset($_POST['email']) ? filter_input(INPUT_POST, 'email', FILTER_SANITIZE_EMAIL) : '';
    $message = isset($_POST['message']) ? htmlspecialchars(trim($_POST['message'])) : '';
}
