<?php
if (isset($_GET['errcode'])) {
    $errorMessages = [
        1 => 'Invalid username or password. Please try again.',
        2 => 'Please login.'
    ];

    $errcode = intval($_GET['errcode']);
    if (array_key_exists($errcode, $errorMessages)) {
        echo '<span style="color: red;">' . htmlspecialchars($errorMessages[$errcode]) . '</span>';
    }
}
?>

This approach keeps the code clean, maintainable, and secure.
