How to use PostgreSQL for data storage in Workerman
Introduction:
With the development of web applications, the demand for data storage and management is increasing. High, and PostgreSQL, as a powerful and reliable open source relational database, is favored by developers. This article will introduce how to use PostgreSQL for data storage in Workerman and provide some specific code examples.
1. Install and configure PostgreSQL
First, we need to install and configure PostgreSQL on the server. Here are some simple steps:
- Install PostgreSQL on the server.
- Create a database and corresponding tables to store our data.
- Create a user and assign it the appropriate permissions.
2. Install and configure Workerman
Next, we need to install and configure Workerman. Here are some simple steps:
-
Install Workerman using Composer:
composer require workerman/workerman
Create a worker.php file and add the following code:
<?php require_once __DIR__ . '/vendor/autoload.php'; use WorkermanWorker; // 創(chuàng)建一個Worker監(jiān)聽指定端口 $worker = new Worker('tcp://0.0.0.0:2345'); // 當(dāng)有客戶端連接時觸發(fā)的回調(diào)函數(shù) $worker->onConnect = function($connection) { echo "New connection "; }; // 當(dāng)收到客戶端消息時觸發(fā)的回調(diào)函數(shù) $worker->onMessage = function($connection, $data) { echo "Received message: $data "; // 在這里可以將數(shù)據(jù)存儲到PostgreSQL中 storeData($data); }; // 啟動worker Worker::runAll(); function storeData($data) { // 連接到PostgreSQL數(shù)據(jù)庫 $conn = pg_connect("host=localhost dbname=mydatabase user=myuser password=mypassword"); if (!$conn) { echo "Unable to connect to PostgreSQL "; exit; } // 執(zhí)行SQL查詢 $result = pg_query($conn, "INSERT INTO mytable (data) VALUES ('$data')"); if (!$result) { echo pg_last_error($conn); exit; } // 關(guān)閉連接 pg_close($conn); }
3. Test the integration of Workerman and PostgreSQL
Now, we can use the following command to start the Worker process and test it:
php worker.php start
Client connects to Workerman:
telnet localhost 2345
Sends a message to Workerman:
Testing Workerman and PostgreSQL integration
Views stored data in the database:
SELECT * FROM mytable;
If everything is fine, you should be able to see the message you just sent.
Summary:
This article details how to use PostgreSQL for data storage in Workerman. By configuring and installing PostgreSQL, and writing the corresponding Workerman code, we can integrate with the database and be able to store and retrieve data. This provides us with powerful tools for developing high-performance web applications. Hope this article helps you!

Why can't localstorage successfully save data?
Jan 03, 2024 pm 01:41 PM
Why does storing data to localstorage always fail? Need specific code examples In front-end development, we often need to store data on the browser side to improve user experience and facilitate subsequent data access. Localstorage is a technology provided by HTML5 for client-side data storage. It provides a simple way to store data and maintain data persistence after the page is refreshed or closed. However, when we use localstorage for data storage, sometimes
Which one is better, swoole or workerman?
Apr 09, 2024 pm 07:00 PM
Swoole and Workerman are both high-performance PHP server frameworks. Known for its asynchronous processing, excellent performance, and scalability, Swoole is suitable for projects that need to handle a large number of concurrent requests and high throughput. Workerman offers the flexibility of both asynchronous and synchronous modes, with an intuitive API that is better suited for ease of use and projects that handle lower concurrency volumes.
