Overview of this book

PHP 7 comes with a myriad of new features and great tools to optimize your code and make your code perform faster than in previous versions. Most importantly, it allows you to maintain high traffic on your websites with low-cost hardware and servers through a multithreading web server. This book demonstrates intermediate to advanced PHP techniques with a focus on PHP 7. Each recipe is designed to solve practical, real-world problems faced by PHP developers like yourself every day. We also cover new ways of writing PHP code made possible only in version 7. In addition, we discuss backward-compatibility breaks and give you plenty of guidance on when and where PHP 5 code needs to be changed to produce the correct results when running under PHP 7. This book also incorporates the latest PHP 7.x features. By the end of the book, you will be equipped with the tools and skills required to deliver efficient applications for your websites and enterprises.

Introduction


In this chapter, we will show you how to set up a simple yet effective mechanism for filtering and validating a block of post data. Then, we will cover how to protect your PHP sessions from potential session hijacking and other forms of attack. The next recipe shows how to protect forms from Cross Site Request Forgery (CSRF) attacks using a randomly generated token. The recipe on password generation shows you how to incorporate PHP 7 true randomization to generate secure passwords. We then show you two forms of CAPTCHA: one that is text based, the other using a distorted image. Finally, there is a recipe that covers strong encryption without using the discredited and soon-to-be-deprecated mcrypt extension.
