PHP in Action

"PHP in Action" is a Kata Series authored by donaldsebleung which is specifically aimed at novice PHP programmers who have learnt the basic syntax and features of the PHP programming language in online courses such as Codecademy but do not know how to apply it in real-world situations. Hence, this Kata Series will focus on the practical aspects of PHP such as sending emails, form validation and setting cookies.

This Kata Series assumes that you have already learnt the fundamentals of PHP such as data types (e.g. strings, numbers, booleans), functions and basic OOP. A good indicator that you are ready for this Kata Series is if you can complete Multiply (8kyu) in PHP and the first four Kata in my Object-Oriented PHP Series without hesitation and without referring to external sources in the process. Since real-world PHP is commonly used in conjunction with HTML and CSS (and sometimes even Javascript), you will also be expected to have a basic understanding of the following programming languages. In certain Kata in this Series where form validation is involved, you may also be expected to be familiar with HTML forms, what attributes they have and how they work.
