In what situations would it be more beneficial to use a PHP book as a reference rather than starting from scratch with online tutorials?

In situations where you need a comprehensive and structured overview of PHP concepts, syntax, and best practices, using a PHP book as a reference can be more beneficial than starting from scratch with online tutorials. Books often provide in-depth explanations, examples, and exercises that can help you grasp complex topics more effectively. Additionally, having a physical reference can be useful for quick lookups and offline learning.

// Example PHP code snippet using a book as a reference
<?php

// Include a PHP book as a reference
include('php_book.php');

// Use the concepts and examples from the book in your code
echo "Hello, PHP book!";
?>
