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!

This article introduces how to configure MongoDB on Debian system to achieve automatic expansion. The main steps include setting up the MongoDB replica set and disk space monitoring. 1. MongoDB installation First, make sure that MongoDB is installed on the Debian system. Install using the following command: sudoaptupdatesudoaptinstall-ymongodb-org 2. Configuring MongoDB replica set MongoDB replica set ensures high availability and data redundancy, which is the basis for achieving automatic capacity expansion. Start MongoDB service: sudosystemctlstartmongodsudosys

This article describes how to build a highly available MongoDB database on a Debian system. We will explore multiple ways to ensure data security and services continue to operate. Key strategy: ReplicaSet: ReplicaSet: Use replicasets to achieve data redundancy and automatic failover. When a master node fails, the replica set will automatically elect a new master node to ensure the continuous availability of the service. Data backup and recovery: Regularly use the mongodump command to backup the database and formulate effective recovery strategies to deal with the risk of data loss. Monitoring and Alarms: Deploy monitoring tools (such as Prometheus, Grafana) to monitor the running status of MongoDB in real time, and

Detailed explanation of MongoDB efficient backup strategy under CentOS system This article will introduce in detail the various strategies for implementing MongoDB backup on CentOS system to ensure data security and business continuity. We will cover manual backups, timed backups, automated script backups, and backup methods in Docker container environments, and provide best practices for backup file management. Manual backup: Use the mongodump command to perform manual full backup, for example: mongodump-hlocalhost:27017-u username-p password-d database name-o/backup directory This command will export the data and metadata of the specified database to the specified backup directory.
