How can PHP superglobals be used consistently throughout code to prevent potential issues?

Using PHP superglobals consistently throughout code can prevent potential issues by ensuring that the variables are always accessed in a predictable and reliable manner. This can help avoid conflicts with variable names, accidental overwriting of values, and improve code readability and maintainability. 

// Example of using PHP superglobals consistently throughout code

$username = $_POST['username'];
$password = $_POST['password'];

// Accessing GET data using $_GET superglobal
$page = $_GET['page'];

// Accessing session data using $_SESSION superglobal
$user_id = $_SESSION['user_id'];
