How can beginners in PHP ensure proper error handling and validation when using includes for dynamic content loading?

Beginners in PHP can ensure proper error handling and validation when using includes for dynamic content loading by implementing try-catch blocks to catch any potential errors that may occur during the include process. Additionally, they can validate input data before including it to prevent any malicious code execution. 

try {
    include 'dynamic_content.php';
} catch (Exception $e) {
    echo 'Error loading dynamic content: ' . $e->getMessage();
}

// Validate input data before including
if (isset($_GET['page'])) {
    $page = $_GET['page'];
    if (preg_match('/^[a-zA-Z0-9_]+$/', $page)) {
        include $page . '.php';
    } else {
        echo 'Invalid page requested';
    }
}
