Catch them all in one go: A complete guide to PHP server optimization, get twice the result with half the effort and be as stable as a mountain!

Server configuration optimization

1. Choose the right server

Selecting the appropriate server is the first step in PHP server optimization. The appropriate server configuration, such as CPU, should be selected based on the traffic and business needs of the website. , memory, hard disk, etc. Generally speaking, for small websites, you can choose an entry-level server; for medium and large websites, it is recommended to choose a high-performance server or cloud server.

2. System optimization

Optimize Server

Operating System

You can improve overall performance by updating the kernel, installing necessary software packages, and disabling unnecessary services. In addition, system logs and junk files should be cleaned regularly to free up storage space.

PHP configuration optimization

1. Memory optimization

Adjustment

php

Memory settings can improve the execution speed of PHP scripts, such as increasing the value of memory_limit to allocate more memory to PHP scripts.

CREATE INDEX index_name ON table_name (column_name);

2. Caching query results

Cache

Database

Query results can reduce the number of database queries and increase query speed.

$cache = new Redis();
$key = "query_result";
if ($cache->exists($key)) {
$result = $cache->get($key);
} else {
$result = $connection->query("SELECT * FROM table_name");
$cache->set($key, $result);
}

cache

1. Page cache

Page caching can store the generated

html

page. When the user visits the same page again, it will be read directly from the cache without regenerating the page, thus improving the response speed of the website.

// 开启页面缓存
ob_start();

// 生成页面内容
$content = "Hello World!";

// 将页面内容输出到缓存
ob_end_flush();

2. CDN

CDN (Content Delivery Network

) can store a website's static resources (such as images,

CSS and javascript files) on servers around the world. When a user accesses a website, the CDN will automatically return static resources to the user from the nearest server, thereby increasing the website's access speed. in conclusion

By optimizing server configuration, PHP configuration, database optimization and caching, the performance of the PHP server can be significantly improved, the response speed and stability of the website can be improved, and the user experience can be improved.
