Are there any recommended resources or books for understanding object-oriented programming (OOP) concepts in PHP, specifically in relation to autoload functions and handling exceptions?

Understanding object-oriented programming (OOP) concepts in PHP, especially in relation to autoload functions and handling exceptions, can be challenging for beginners. To gain a better understanding of these topics, it is recommended to refer to resources such as "PHP Objects, Patterns, and Practice" by Matt Zandstra and "Modern PHP: New Features and Good Practices" by Josh Lockhart. These books provide comprehensive explanations and examples that can help clarify these concepts.

spl_autoload_register(function ($class) {
    include 'classes/' . $class . '.php';
});

try {
    // Code that may throw an exception
} catch (Exception $e) {
    echo 'Caught exception: ' . $e->getMessage();
}
