Can you recommend any intermediate to advanced PHP books for someone with experience in web development but looking to deepen their PHP knowledge?

To deepen PHP knowledge for someone with experience in web development, I recommend the following intermediate to advanced PHP books: 1. "Modern PHP: New Features and Good Practices" by Josh Lockhart - This book covers advanced PHP features and best practices for modern PHP development. 2. "PHP Objects, Patterns, and Practice" by Matt Zandstra - This book delves into object-oriented programming in PHP and design patterns for building scalable and maintainable applications. 3. "PHP Advanced and Object-Oriented Programming" by Larry Ullman - This book explores advanced PHP concepts such as namespaces, traits, and generators, as well as best practices for writing efficient and secure PHP code. I hope these recommendations help you deepen your PHP knowledge!

// Sample PHP code snippet to demonstrate advanced PHP concepts
namespace MyNamespace;

trait MyTrait {
    public function doSomething() {
        // Trait method implementation
    }
}

class MyClass {
    use MyTrait;

    public function __construct() {
        // Constructor logic
    }
}

$obj = new MyClass();
$obj->doSomething();
