PHP7 Basic Development Principles Practical Manual: Implementing Efficient PHP Code and Extensions

With the rapid development of the Internet, PHP, as a commonly used server-side scripting language, It is also undergoing continuous iteration and optimization. PHP7, as the latest version, brings many improvements in performance and language features, making the execution of PHP code more efficient. The underlying development principles of PHP7 are the key to our in-depth understanding and application of PHP7.

This article will introduce the underlying development principles of PHP7 in the form of a practical manual to help readers implement efficient PHP code and extensions. We will introduce it in the following parts:

1. PHP7 underlying architecture
   Before understanding the underlying development principles of PHP7, we need to understand the underlying architecture of PHP7. The bottom layer of PHP7 is mainly composed of Zend engine and language core. Zend engine is the core of PHP7 and is responsible for parsing and executing PHP code. The language core contains PHP's built-in functions and language features.
2. Performance improvements of PHP7
   PHP7 has brought many performance improvements compared to PHP5. The most important improvement is the introduction of a new PHPNG engine, which greatly improves the execution speed of PHP code. We will introduce how the PHPNG engine works and demonstrate its performance improvements through code examples.
3. New features of PHP7
   PHP7 introduces many new language features, such as scalar type declaration, return type declaration, etc. We'll introduce the syntax and usage of these new features, and show them in action with code examples.
4. PHP extension development
   PHP’s extension mechanism is an important feature of PHP7. PHP extensions can provide more functionality and performance optimizations to PHP. We will introduce the basic processes and techniques of PHP extension development, and demonstrate how to develop a simple PHP extension through a practical example.

Throughout the practical manual, we will use a large number of code examples to help readers better understand and apply the underlying development principles of PHP7. Through actual practice, readers will be able to master how to write efficient PHP code and develop their own PHP extensions.

Summary:
PHP7 underlying development principles practical manual is the key to helping readers deeply understand and use PHP7. By understanding the underlying architecture, performance improvements and new features of PHP7, and mastering the skills of PHP extension development, readers can write efficient PHP code and develop their own PHP extensions. I hope this article can help readers better learn and apply PHP7.
