What are the differences between a PHP manual and a tutorial, and how can they affect learning PHP effectively?

A PHP manual is a comprehensive reference guide that provides detailed explanations of PHP functions, syntax, and features. On the other hand, a tutorial is a step-by-step guide that teaches how to use PHP to accomplish specific tasks or projects. Using a PHP manual can help in understanding the core concepts and functionalities of PHP, while tutorials can provide practical examples and hands-on experience in using PHP effectively.
