Comprehensive list of PHP server optimization tips: including 20 practical tips to easily improve website speed

1. Choose the appropriate PHP version

The "Complete PHP Server Optimization Tips" brought by php editor Baicao covers 20 practical tips that can help the website speed up and improve performance. These tips are designed to optimize the configuration of the PHP server, reduce loading time, increase response speed, and allow users to easily experience a smoother website access experience.

2. Optimize PHP configuration file

Some settings in the PHP configuration file can have a significant impact on server performance. For example, memory limits, maximum execution time, post_max_size, etc. can be adjusted to improve the server's processing power and throughput.

3. Use PHP extension

PHP extensions can add additional functionality to the PHP server, such as the Memcached extension which can improve the performance of database queries, and the APC extension which can cache PHP scripts to speed up execution.

4. Use an efficient database engine

When selecting a database engine, in addition to the compatibility of the database, the performance of the database must also be considered. Generally speaking, Mysql and postgresql are database engines with better performance.

5. Optimize database query

Database query is one of the most common operations during the operation of the website, so Optimization Database query can significantly improve the performance of the website. You can use the explain command to analyze the query execution plan and optimize it based on the analysis results.

6. Use caching mechanism

The cache mechanism can store frequently accessed data in memory so that it can be read directly from memory the next time it is accessed, thereby reducing the number of database queries and improving website performance. You can use Memcached, Redis and other caching tools to implement the caching function.

7. Optimize static file transmission

Static files, such as images,

CSS, javascript, etc., account for a large proportion of website transmission. Optimizing static file transfer can reduce website loading time and improve user experience. Technologies such as CDN and GZIP compression can be used to optimize static file transfer.

8. Use reverse proxy server

The reverse proxy server can forward client requests to different servers to achieve

load balancing and failover. Using a reverse proxy server can reduce the load on the server and improve the availability and reliability of the website.

9. Optimize front-end code

Front-end Code is also an important factor affecting website performance. Technologies such as compression, merging, and asynchronous loading can be used to optimize the front-end code and reduce the loading time of the website.

10. Use performance monitoring tools

Use performance

MonitoringTools can help us discover website performance bottlenecks and take appropriate measures to optimize. Commonly used performance monitoring tools include New Relic, AppDynamics, prometheus, etc.

11. Use CDN service

The CDN service can cache the static resources of the website to edge servers around the world, thereby reducing the loading time of the website and improving the user experience. Commonly used CDN service providers include Baidu Cloud CDN,

Alibaba CloudCDN, Tencent CloudCDN, etc.

12. Optimize website images

Website images are an important factor affecting website loading speed. You can compress and crop website images to reduce the size of the images and improve the loading speed of the website.

13. Enable Gzip compression

Gzip compression can reduce the transmission size of the website and improve the loading speed of the website. Gzip compression can be enabled on the server to achieve this.

14. Optimize website CSS and JavaScript code

Website CSS and JavaScript code are also important factors that affect website loading speed. You can compress and merge website CSS and JavaScript codes to reduce code size and improve website loading speed.

15. Use browser cache

Browser cache can cache the static resources of the website into the local storage of the browser, thereby reducing the loading time of the website and improving the user experience. You can set cache control instructions in the

Http header information of the website to enable browser caching.

16. Use persistent connections

Persistent connections can reduce the number of connections between the website and the server and improve the loading speed of the website. You can set the Connection directive in the website's HTTP header information to enable persistent connections.

17. Optimize website database

The website database is also an important factor affecting the loading speed of the website. The website database can be optimized to increase the query speed of the database. You can create index, optimize query statements, and use caching and other technologies to optimize the website database.

18. Use CDN service

The CDN service can cache the static resources of the website to edge servers around the world, thereby reducing the loading time of the website and improving the user experience. Commonly used CDN service providers include Baidu Cloud CDN, Alibaba Cloud CDN, Tencent Cloud CDN, etc.

19. Enable Gzip compression

Gzip compression can reduce the transmission size of the website and improve the loading speed of the website. Gzip compression can be enabled on the server to achieve this.

20. Use browser cache

Browser cache can cache the static resources of the website into the local storage of the browser, thereby reducing the loading time of the website and improving the user experience. Cache control instructions can be set in the HTTP header information of the website to enable browser caching.
