Get a complete guide to the underlying development principles of PHP8: Take advantage of new features to optimize applications
Abstract: PHP is a popular server-side scripting language for Develop dynamic web applications. PHP8 is the latest version of PHP, which introduces many new underlying development principles and features that can help developers optimize their applications. This article will delve into the underlying development principles of PHP8 and provide some practical suggestions for taking advantage of new features to optimize applications.
Introduction:
With the growing demand for web applications, PHP has become a very popular server-side scripting language. Developers use PHP to develop dynamic websites, web applications, and web services. With the release of PHP 8, developers can now take advantage of new underlying development principles and features to further improve their application performance and security.
1. New features of PHP8:
PHP8 introduces many new underlying development principles and features, including:
- JIT compiler: PHP8 introduces JIT (Just- In-Time) compiler, which converts PHP code into native machine code, providing higher execution speed. Developers can speed up their applications by enabling the JIT compiler.
- Named parameters: PHP8 introduced named parameters, allowing developers to pass parameters by name instead of position. This improves code readability and reduces bugs caused by incorrect parameter placement.
- Distinguish between shared and static properties: PHP8 allows developers to distinguish between shared and static properties in class definitions. This allows for better organization and management of code, as well as improved code readability.
- New type system: PHP8 introduces a new set of type systems, including union types and the null coalescing operator. These new features enable developers to more clearly define and work with data types, thereby improving application stability.
2. How to make full use of the new features of PHP8 to optimize applications:
To make full use of the new features of PHP8 to optimize applications, developers can consider the following points:
- Use the JIT compiler to improve performance: Enabling the JIT compiler can greatly improve the performance of your PHP application. Developers should evaluate whether their applications can benefit from a JIT compiler and configure them accordingly.
- Use named parameters to improve code readability: By using named parameters, developers can improve code readability and reduce bugs caused by incorrect parameter placement. Developers should take advantage of this new feature to make their code easier to understand and maintain.
- Organize and manage shared and static properties in code: PHP8 allows developers to clearly distinguish between shared and static properties in class definitions. Developers should take full advantage of this feature to better organize and manage their code and improve code readability and maintainability.
- Clearly define and handle data types: PHP8 introduces a new set of type systems that enable developers to more clearly define and handle data types. Developers should fully understand these new features and use them in their code to improve the stability and reliability of their applications.
Conclusion:
PHP8 introduces many new underlying development principles and features that can help developers optimize their applications. By taking full advantage of PHP8's new features, developers can improve the performance, readability, and maintainability of their applications. Therefore, developers should update their PHP versions in a timely manner and learn and apply these new features to continuously optimize their applications.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.
