Typed PHP [PDF ebook] 
Stronger Types For Cleaner Code

Discover how stronger types mean cleaner, more efficient, and optimized PHP applications. This unique book looks at typed PHP: PHP types, strings, regular expressions, and more from PHP 7 as found in standard PHP libraries, user libraries, extensions, and cross-compilers. You’ll see how to create a set of reusable tools that unify and ease the scalar types of PHP.

PHP has a rich history and a dominant place on the web. It has achieved much despite language inconsistencies and difficulties. Bjarne Stroustrup once said: ‘There are only two kinds of languages: the ones people complain about and the ones nobody uses’.

PHP is one of those languages that everybody uses, yet that’s often seen as a good reason to ignore the bad parts and just get stuff done. We’re all for getting stuff done, and to that end, the author has used Plain Ol’ PHP for many years. It’s always bugged him how procedural PHP is, in an ecosystem of OOP libraries and frameworks. So he decided to takea deeper look at building a stronger type system on top of PHP. That’s the goal of this book.
