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".
