The best performance optimization tips in PHP development CMS programming

With the continuous development of Internet technology, CMS (Content Management System) has become the first choice for many corporate and personal website construction. PHP, as a popular server-side programming language, is also widely used in CMS development. . However, an efficient CMS website requires efficient programming skills and optimization skills. This article will introduce some of the best performance optimization skills in PHP development CMS programming.

1. Cache Optimization
   Cache is an important means to improve website performance. In PHP CMS, cache can be divided into static cache and dynamic cache. Static caching is to cache static files such as HTML, CSS, JavaScript, etc., while dynamic caching is to cache dynamic pages such as PHP web pages. The method of caching optimization is as follows:
2. Write the reference paths of static files such as CSS and JavaScript as absolute paths
3. Use CDN (content distribution network) to accelerate static file access speed
4. Reasonable settings Cache time, properly cache PHP dynamic pages
5. Database Optimization
   CMS websites usually store a large number of articles, pictures, comments and other data, which are stored in the database. Database optimization can reduce database access time. Common database optimization methods include:
6. Write efficient SQL statements to reduce the number of database queries
7. Optimize the table structure and set indexes reasonably
8. Use in-memory database Redis, etc. Caching database query results
9. Code optimization
   Code optimization is the most basic step in CMS performance optimization. The following are common code optimization tips:
10. Avoid using the eval function in PHP, because the eval function will reduce execution efficiency
11. Avoid using global variables, because global variables need to query the scope chain, increase Reduce program execution time
12. Reduce the number of function calls to a minimum, because function calls will increase the time overhead of function return and parameter passing
13. Use compiler cache
    Compiler cache refers to The compiled files are cached to avoid the need to recompile every time the PHP file is executed. Commonly used compiler caches in PHP include APC, Xcache, etc. Using compiler caching can effectively improve the performance of your CMS website.
14. Server Optimization
    Server optimization is the backup means for CMS website performance optimization. Through server optimization, the access time of the CMS website can be reduced and the response speed can be improved. Server optimization tips are as follows:
15. Try to use high-performance server hardware. Investing more in hardware can improve server performance
16. Use professional server management software such as nginx, etc., and avoid using Apache, etc. Inefficient server
17. Configure the server’s caching strategy, such as periodically clearing cache files

Through the above CMS programming performance optimization techniques, we can effectively improve the response of the CMS website speed and access efficiency, making it a more efficient website. These optimization techniques need to be used flexibly in actual development. This article only provides some basic principles and suggestions, and the specific operations will depend on the actual situation.
