How to use MongoDB for data storage in Workerman
How to use MongoDB for data storage in Workerman
Workerman is a high-performance network programming framework based on PHP, which provides rich functions and flexible extensions features, making it easier for developers to build high-performance network applications. MongoDB is a non-relational database known for its high performance, high scalability and flexible data model, and is widely used in large-scale data storage and processing.
In this article, we will introduce how to use MongoDB for data storage in Workerman and provide specific code examples.
Step 1: Install the MongoDB driver
First, make sure that the PHP MongoDB extension driver is installed. You can use the following command to install:
pecl install mongodb
After the installation is complete, you need to enable the MongoDB extension in the php.ini file. You can use the following command to edit the php.ini file:
vim /etc/php.ini
Add the following line of configuration in the php.ini file:
extension=mongodb.so
Save and exit, restart the PHP service to make it effective:
service php-fpm restart
Step 2: Create a database connection
Before using MongoDB in an application, you need to create a database connection. You can create a connection in the Workerman startup function and save it using global variables in the application:
// 引入MongoDB驱动 require_once __DIR__ . '/mongodb/autoload.php'; use MongoDBClient; // 创建MongoDB连接 $GLOBALS['mongo'] = new Client('mongodb://localhost:27017');
Step 3: Insert data
After you have a database connection, you can insert data. The following is a simple example to insert a piece of data into the user collection of the database named test:
// 获取MongoDB的连接 $mongo = $GLOBALS['mongo']; // 选择数据库 $db = $mongo->test; // 选择集合 $collection = $db->user; // 插入一条数据 $collection->insertOne([ 'name' => 'John', 'age' => 25, 'email' => 'john@example.com' ]);
Step 4: Query data
In addition to inserting data, you can also perform data query operations. The following is a simple example to query all users whose age is less than 30 from the user collection of the database named test:
// 获取MongoDB的连接 $mongo = $GLOBALS['mongo']; // 选择数据库 $db = $mongo->test; // 选择集合 $collection = $db->user; // 查询数据 $cursor = $collection->find([ 'age' => ['$lt' => 30] ]); // 遍历查询结果 foreach ($cursor as $document) { var_dump($document); }
Step 5: Update data
In MongoDB, you can use the updateOne() method to update a piece of data. The following is a simple example to update the mailbox of a user whose age is equal to 25 in the user collection of the database named test:
// 获取MongoDB的连接 $mongo = $GLOBALS['mongo']; // 选择数据库 $db = $mongo->test; // 选择集合 $collection = $db->user; // 更新数据 $collection->updateOne( ['age' => 25], ['$set' => ['email' => 'updated@example.com']] );
Step 6: Delete data
Finally, you can use the deleteOne() method to delete a piece of data. The following is a simple example to delete the user named John from the user collection of the database named test:
// 获取MongoDB的连接 $mongo = $GLOBALS['mongo']; // 选择数据库 $db = $mongo->test; // 选择集合 $collection = $db->user; // 删除数据 $collection->deleteOne(['name' => 'John']);
Through the introduction of the above steps and specific code examples, I believe readers can successfully use it in Workerman MongoDB performs data storage. I hope this article is helpful to developers, thank you for reading!

It is recommended to use the latest version of MongoDB (currently 5.0) as it provides the latest features and improvements. When selecting a version, you need to consider functional requirements, compatibility, stability, and community support. For example, the latest version has features such as transactions and aggregation pipeline optimization. Make sure the version is compatible with the application. For production environments, choose the long-term support version. The latest version has more active community support.

Node.js is a server-side JavaScript runtime, while Vue.js is a client-side JavaScript framework for creating interactive user interfaces. Node.js is used for server-side development, such as back-end service API development and data processing, while Vue.js is used for client-side development, such as single-page applications and responsive user interfaces.

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

The data of the MongoDB database is stored in the specified data directory, which can be located in the local file system, network file system or cloud storage. The specific location is as follows: Local file system: The default path is Linux/macOS:/data/db, Windows: C:\data\db. Network file system: The path depends on the file system. Cloud Storage: The path is determined by the cloud storage provider.

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.

The MongoDB database is known for its flexibility, scalability, and high performance. Its advantages include: a document data model that allows data to be stored in a flexible and unstructured way. Horizontal scalability to multiple servers via sharding. Query flexibility, supporting complex queries and aggregation operations. Data replication and fault tolerance ensure data redundancy and high availability. JSON support for easy integration with front-end applications. High performance for fast response even when processing large amounts of data. Open source, customizable and free to use.

MongoDB is a document-oriented, distributed database system used to store and manage large amounts of structured and unstructured data. Its core concepts include document storage and distribution, and its main features include dynamic schema, indexing, aggregation, map-reduce and replication. It is widely used in content management systems, e-commerce platforms, social media websites, IoT applications, and mobile application development.

The dat file is a universal data file format that can be used to store various types of data. dat files can contain different data forms such as text, images, audio, and video. It is widely used in many different applications and operating systems. dat files are typically binary files that store data in bytes rather than text. This means that dat files cannot be modified or their contents viewed directly through a text editor. Instead, specific software or tools are required to process and parse the data of dat files. d
