Server Optimization Secrets: Revealing the underlying development principles of PHP8

Server Optimization Cheats: Revealing the underlying development principles of PHP8

With the rapid development of the Internet, server optimization has become more and more important. For websites developed using PHP language, understanding the underlying development principles of PHP is crucial for server optimization. This article will reveal the underlying development principles of PHP8 and share some server optimization tips.

1. Introduction to the underlying development principles of PHP8
PHP is a scripting language developed in C language. Under the hood, PHP uses the Zend Engine to parse and execute code. Zend Engine is the core engine of PHP, which is responsible for converting PHP code into an executable instruction set. Zend Engine provides a wide range of functions, including memory management, garbage collection, compilation and execution of code, etc.

PHP8 is the latest version of the PHP language. Compared with previous versions, PHP8 introduces many new features and improvements. One of the most important improvements is the introduction of the JIT (Just-In-Time) compiler. The JIT compiler can compile frequently used code into machine code and cache it for subsequent use. This can significantly improve the execution speed of your code.

2. Server optimization tips

1. Use the latest PHP version
   PHP8 has introduced many performance optimizations and improvements, so using the latest PHP version can bring better performance and greater efficiency. At the same time, the latest PHP version usually contains many bug fixes and security improvements, which can improve the stability and security of the server.
2. Enable OPcache
   OPcache is a built-in module of PHP that is used to cache the compilation results of PHP code. Enabling OPcache can reduce the number of code compilations, thereby increasing the code execution speed. In PHP8, OPcache has also made some improvements, including more efficient memory management and better caching mechanism.
3. Use JIT compiler
   The JIT compiler is a major feature of PHP8. It can compile frequently used code into machine code and cache it for subsequent use. Using a JIT compiler can significantly improve the execution speed of your code. The JIT compiler can be enabled and configured by setting the "opcache.jit_buffer_size" and "opcache.jit" parameters in the php.ini file.
4. Optimize database query
   Database query is an important part of website performance, and optimizing database query can significantly improve website performance. Database queries can be optimized by using indexes rationally, avoiding full table scans, reducing unnecessary queries, and using cache. In addition, using technologies such as database connection pooling and asynchronous query can also improve the performance of database queries.
5. Use caching technology
   Caching technology can significantly improve the performance of the website. You can use caching to store frequently used data and results, thereby reducing the number of database queries and calculations. Commonly used caching technologies include Redis, Memcached and APC.
6. Optimize code
   Optimizing code can improve the execution speed and efficiency of the code. Code can be optimized by reducing unnecessary function calls, using more efficient algorithms, avoiding duplication of code, and using parallel computing. In addition, timely release of memory and avoidance of memory leaks are also important parts of optimizing code.

3. Summary
Server optimization is crucial to improving the performance and performance of the website. Understanding the underlying development principles of PHP8 and some optimization tips can help us better optimize the server. This article introduces the underlying development principles of PHP8 and shares some server optimization tips. I hope this content will be helpful for server optimization.
