In what ways can the lack of context switching affect the functionality of PHP scripts handling form data?

The lack of context switching in PHP scripts handling form data can lead to errors or unexpected behavior when trying to access form variables directly. To avoid this issue, it is recommended to use the `$_POST` or `$_GET` superglobals to access form data securely within the same context. 

// Using $_POST superglobal to access form data securely
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST["username"];
    $password = $_POST["password"];
    
    // Process form data securely within the same context
}
