Preface

PHP is a great language for developing web applications. It is essentially a server-side scripting language that is also used for general-purpose programming. PHP 7 is the latest version, which provides major backward-compatibility breaks and focuses on providing improved performance and speed. With the rise in demand for high performance, this newest version contains everything you need to build efficient applications. PHP 7 provides improved engine execution, better memory usage, and a better set of tools allowing you to maintain high traffic on your websites with low-cost hardware and servers through a multithreading web server.
