PHP-FPM Performance Optimization Practice: Methods to Improve Website Data Reading and Writing Speed

Introduction:

With the rapid development of the Internet, website applications Procedures are increasingly important. In the process of building a website with stable business and good user experience, optimizing data reading and writing speed is a crucial part. As a high-performance, scalable PHP solution, PHP-FPM can help us improve the data reading and writing speed of the website. This article will introduce some practical methods of PHP-FPM performance optimization and provide specific code examples.

1. Use cache to accelerate data reading

Data reading is one of the most frequent operations during the operation of the website. Using cache can greatly reduce the number of database queries, thereby improving the response speed of the website. In PHP-FPM, caching systems such as Memcached or Redis can be used to implement caching functions.

Sample code:

$cacheKey = 'cache_key';
$data = $cache->get($cacheKey);
if (!$data) {
    $data = $database->query('SELECT * FROM table')->fetchAll();
    $cache->set($cacheKey, $data, 3600);
}

2. Optimize database query

Database query is one of the common causes of website performance bottlenecks. Optimizing database queries can significantly improve the data reading speed of your website.

1. Use indexes: Adding appropriate indexes to database tables can speed up queries. For example, you can add indexes on columns that are frequently searched.
2. Batch operations: Try to use batch queries or updates to reduce the number of database connections. For example, use an IN statement instead of a loop query.

Sample code:

$ids = [1, 2, 3, 4, 5];
$placeholders = implode(',', array_fill(0, count($ids), '?'));
$query = $pdo->prepare("SELECT * FROM table WHERE id IN ($placeholders)");
$query->execute($ids);
$result = $query->fetchAll();

3. Use asynchronous non-blocking IO

PHP-FPM’s default synchronous blocking IO model is not suitable for high-concurrency websites. Efficient. The asynchronous non-blocking IO model can be used to improve the performance of PHP-FPM.

1. Use Swoole extension: Swoole is a high-performance asynchronous non-blocking IO network framework that can be used in conjunction with PHP-FPM to provide higher concurrent processing capabilities.
2. Use coroutines: Coroutines are lightweight threads that can switch multiple tasks in one thread, thereby avoiding the overhead of thread switching.

Sample code:

Coun(function () {
    go(function () {
        $result = Co::exec('ls');
        var_dump($result);
    });
});

Conclusion:

Through the above method, we can optimize the performance of PHP-FPM and improve the data reading and writing speed of the website. Using cache to speed up data reading, optimizing database queries and using asynchronous non-blocking IO are common optimization methods. Of course, these are just some simple practical methods, and the specific optimization plan needs to be determined based on the actual situation of the website. I hope this article has been helpful to you in optimizing website performance.
