How can the PHP superglobal arrays like $_POST and $_FILES be utilized to access form data effectively?

To access form data effectively using PHP superglobal arrays like $_POST and $_FILES, you can simply use them to retrieve the values submitted through a form. $_POST is used for retrieving form data sent with the POST method, while $_FILES is used for accessing file uploads. By accessing these superglobal arrays, you can easily retrieve and process the form data submitted by users. 

// Accessing form data submitted using the POST method
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST['username'];
    $password = $_POST['password'];
    
    // Process the form data as needed
}

// Accessing file uploads
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $file_name = $_FILES['file']['name'];
    $file_tmp = $_FILES['file']['tmp_name'];
    
    // Process the file upload as needed
}
