Data structure optimization skills in PHP high concurrency processing

With the rapid development of the Internet, more and more websites are facing the challenge of high concurrent access. In PHP development, how to optimize the data structure and improve the concurrent processing capability of the program has become an important task. This article will introduce several commonly used data structure optimization techniques and give corresponding code examples.

1. Use caching technology

Cache technology is one of the effective means to improve the concurrent processing capability of the system. Caching can reduce database access pressure and improve program response speed. In PHP, we can use caching systems such as Redis or Memcached to implement caching functions.

Code example:

// Using Redis cache
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
$redis->set('key', 'value');
$value = $redis->get('key');

// Use Memcached cache
$memcached = new Memcached();
$memcached->addServer('127.0.0.1', 11211);
$memcached->set('key', 'value');
$value = $memcached->get('key');

2. Use lock-free data structures

In PHP's concurrent processing, using lock-free data structures can effectively avoid Competition between multiple threads improves the concurrency performance of the program. PHP provides extension tools such as Swoole, which can use lock-free queues, lock-free hash tables and other lock-free data structures.

Code example:

// Using Swoole lock-free queue
$queue = new SwooleLockQueue();
$queue->push('value');
$value = $queue->pop();

// Use Swoole lock-free hash table
$hashTable = new SwooleLockHashTable();
$hashTable->set(' key', 'value');
$value = $hashTable->get('key');

3. Use distributed storage

Distributed storage is in PHP One of the commonly used data structure optimization techniques. By distributing data to different storage nodes, the concurrent processing capability and scalability of the system can be improved. Common distributed storage systems include MySQL Cluster, MongoDB, etc.

Code example:

// Using MySQL Cluster distributed storage
$cluster = new mysqli_cluster();
$cluster->add_connection('127.0.0.1', 'user', 'password');
$cluster->use_database('db');
$result = $cluster->query('SELECT * FROM table');

// Using MongoDB distributed storage
$manager = new MongoDBDriverManager("mongodb://localhost:27017");
$query = new MongoDBDriverQuery([]);
$cursor = $manager- >executeQuery('test.collection', $query);

4. Using concurrent queues

In PHP high-concurrency processing, using concurrent queues can effectively decouple task processing and front-end ask. By placing tasks in the queue and processing them asynchronously by the background process, the waiting time of front-end requests can be reduced and the concurrent processing capabilities of the system can be improved.

Code example:

// Using Laravel Queue
$job = (new SendEmailJob($email))->onQueue('emails');
dispatch($ job);

// Using Symfony Queue
$producer = $this->get('old_sound_rabbit_mq.mailing_producer');
$producer->publish(serialize($data)) ;

To sum up, the data structure optimization skills in PHP high-concurrency processing are the key to improving the system's concurrent processing capabilities. By using technical means such as caching technology, lock-free data structures, distributed storage, and concurrent queues, the concurrency performance of the program can be effectively improved. I hope this article will be helpful to your data structure optimization in PHP development.
