PHP has been at the helm of the web for many years. It is an extremely popular, interpreted scripting language that is ideally suited for web development in part because it has an approachable syntax and supports different operating systems. This language powers millions of web sites on the net and is extremely well supported by its user community.
The language is released under a non-copyleft free software license / open source license. The latest stable version adds lots of new features.
1. PHP: The Right Way by Josh Lockhart, Phil Sturgeon
PHP: The Right Way is an easy-to-read, quick reference for PHP best practices, accepted coding standards, and links to authoritative tutorials around the Web. It aims to introduce new developers to some topics which they may not discover until it’s too late, and seeks to give seasoned developers some fresh ideas.
Topics covered include coding practices, dependency injection, databases, templating, errors and exceptions, security, testing, virtualization and more.
The book has been translated into German, Spanish, French, Italian, Polish, and many other languages.
