PHP 8

The book provides a detailed and comprehensive presentation of the PHP 8 language from simple to complex. It can be used both for learning the language from scratch and for structuring knowledge, studying the nuances of syntax and the new features of the latest version. All significant innovations are described. New types, attributes, enumerations, named arguments, matches, union types, the new operators ??= and ?->, and much more are discussed. The main focus of the book is on the object-oriented capabilities of the language, so classes and objects are addressed almost from the very first chapters. A description of PHP syntax is provided, as well as tools for working with arrays, files, PostgreSQL databases, Redis, regular expressions, graphic primitives, sessions, etc.
