How to use MongoDB for data storage in ThinkPHP6

With the continuous development of the Internet, data storage and processing have become increasingly important. MongoDB is a NoSQL database suitable for large-scale data and high-performance application scenarios. Its high performance and scalability have been supported by many developers. In this article, we will introduce how to use MongoDB for data storage in ThinkPHP6.

1. Install the MongoDB extension

First, we need to install the MongoDB extension on the server so that we can use MongoDB for data storage in ThinkPHP6. Here, I use Windows system as an example to explain the installation method of MongoDB.

1. Download the MongoDB extension

We can go to the PHP official website and choose the MongoDB extension that suits us to download. At the same time, we also need to download the corresponding MongoDB C driver to link MongoDB with PHP.

2. Install MongoDB extension and C driver

After decompressing the downloaded MongoDB extension, copy the PHP extension to the /ext directory of PHP and add it to the php.ini file Add the following configuration:

extension=php_mongodb.dll

Next, we also need to decompress the downloaded MongoDB C driver and add the bin directory path to the system environment. in variables.

3. Start the MongoDB service

After installing the MongoDB extension and C driver, we also need to install the MongoDB service. You can download the corresponding installation program from the MongoDB official website and install it.

4. Configure MongoDB connection

In ThinkPHP6, we can add the following configuration information in the config/database.php file:

'mongodb' => [

'hostname'        => '127.0.0.1',
'database'        => 'test',
'username'        => '',
'password'        => '',
'hostport'        => '27017',
'dsn'             => '',
'params'          => [
    'socketTimeoutMS' => 1000,
],

],

The MongoDB connection address, database name, user name, password and other information are configured here.

2. Use MongoDB for data storage

1. Establish a data model

In ThinkPHP6, we can establish the MongoDB data model through Model. In the Model, we can operate the MongoDB database through the MongoDB API.

For example:

namespace appmodel;

use thinkModelMongoDb;

class User extends MongoDb
{

protected $connection = 'mongodb';
protected $pk = '_id';
protected $table = 'user';

}

Here, we created a model named User, which inherits the MongoDb class. In the model, we need to configure the MongoDB connection information and set the primary key and data table name.

2. Insert data

When using MongoDB for data storage, we can operate MongoDB through the model's API. Taking inserting data as an example, the code is as follows:

$user = new User;
$user->name = 'Zhang San';
$user->age = 20;
$user->sex = 'Male';
$user->save();

Here, we instantiate a User model, set the basic information of the user, and The save() method is called to insert data into the MongoDB database.

3. Query data

When using MongoDB for data query, we can complete it through the API of the model. For example, query the information of all users:

$user = new User;
$list = $user->select();
dump($list);

Here, we instantiate a User model and call the select() method to query the data in MongoDB. At the same time, we use the dump() function to output the query results.

4. Update data

When using MongoDB to update data, we can do it through the model's API. For example, update a user's information to new information:

$user = new User;
$user->where('_id', '5f1020d7bb8bde619e3d1632')->update([ 'name' => '李思']);

Here, we instantiate a User model and call the where() method to specify the user to be updated, and use the update() method to The user's information is updated.

5. Delete data

When using MongoDB to delete data, we can do it through the model's API. For example, delete a user's information:

$user = new User;
$user->where('_id', '5f1020d7bb8bde619e3d1632')->delete();

Here, we instantiate a User model, call the where() method, specify the user to delete, and use the delete() method to delete the user's information.

3. Summary

In this article, we introduced how to use MongoDB for data storage in ThinkPHP6. First, we need to install the MongoDB extension on the server and configure the MongoDB connection information. Then, by using Model to establish the MongoDB data model, you can use MongoDB's API to complete operations such as data insertion, query, update, and deletion. Hope this article is helpful to everyone.
