A guide to the underlying development principles of PHP8: speed up your server

As a popular server-side programming language, PHP8 has always been widely popular for its simplicity, ease of use and highly scalable features. However, as applications and websites increase in complexity, so do the performance requirements on servers. In order to meet this demand, PHP8 introduces some new underlying development principles and technologies that can speed up your server and improve application performance.

1. Introduction of JIT compiler

PHP8 introduces JIT (Just-in-Time) compiler, which is a real-time compiler that can directly compile PHP code into local machine code , thereby improving execution speed. Before PHP7, PHP code was executed through an interpreter. Each execution required converting the PHP code into machine code. This process was time-consuming. The JIT compiler can cache already compiled code, reducing repeated compilation processes, thus improving performance.

2. Type declaration of attributes

PHP8 imposes stricter constraints on the type of attributes and introduces the concept of type declaration. Developers can specify specific types for properties, thereby improving code readability and stability. Type declarations prevent incorrect data types from being assigned to properties and avoid potential bugs. In addition, PHP8 also introduces a new mixed type, which can represent any type of data, allowing developers to handle data type issues more flexibly in some cases.

3. Improvements in memory management

PHP8 has made a series of improvements to memory management, including the introduction of a new garbage collection mechanism and optimized memory allocation and release performance. PHP8 uses a generational garbage collection algorithm, which performs generational generation according to the survival time and size of objects, reducing the frequency and cost of garbage collection and improving memory utilization. In addition, PHP8 also introduces the concept of weak references, which can better manage memory resources and prevent memory leaks.

4. Support for asynchronous programming

PHP8 introduces support for asynchronous programming, which is implemented through new asynchronous operators and asynchronous functions. Asynchronous programming can improve server throughput and responsiveness because it can perform one operation without blocking other operations. This is important for applications that handle large numbers of concurrent requests. PHP8 makes asynchronous programming simpler and more efficient by introducing the concept of coroutine.

Summary:

PHP8 can greatly improve the performance of the server with the help of new underlying development principles and technologies such as the JIT compiler, attribute type declaration, memory management improvements, and asynchronous programming support. . Developers can take advantage of these new features to speed up their servers and improve application performance. However, to take full advantage of these new features, developers need to have a certain understanding of the underlying working principles of PHP8 and apply these new technologies appropriately. I hope this article can help readers deepen their understanding of the underlying development principles of PHP8 and speed up their servers in actual development.
