How to use ORM with Medoo framework?

Medoo is a simple and powerful PHP database framework. Its ORM function can help us perform database operations more conveniently. This article will introduce how to use ORM in Medoo framework.

1. Install the Medoo framework

To use the Medoo framework, you first need to install it into your project. Medoo can be installed through Composer. Just add the following dependencies in the project's composer.json file:

"require": {
    "catfan/Medoo": "^1.4"
}

Then run the composer install command in the project root directory to complete the installation.

2. Configuring the database connection

Before using the Medoo framework, you need to configure the database connection first. You can create a new config.php file in the project to store database connection information.

<?php

$config = [
    'database_type' => 'mysql',
    'database_name' => 'test_db',
    'server' => 'localhost',
    'username' => 'root',
    'password' => '123456',
    'charset' => 'utf8'
];

Here we take the MySQL database as an example and store the database type, name, server address, user name, password, character set and other information in the $config array.

3. Create model classes

The ORM function in the Medoo framework is mainly implemented through model classes. We need to create a corresponding model class for each database table.

For example, we have a users table to store user information. We can create a User model class to operate on this table.

<?php

require_once 'vendor/autoload.php';
require_once 'config.php';

use MedooMedoo;

class User
{
    private $db;

    public function __construct()
    {
        $this->db = new Medoo($GLOBALS['config']);
    }

    public function getAll()
    {
        return $this->db->select('users', '*');
    }

    public function getById($id)
    {
        return $this->db->get('users', '*', ['id' => $id]);
    }

    public function add($data)
    {
        return $this->db->insert('users', $data);
    }

    public function update($id, $data)
    {
        return $this->db->update('users', $data, ['id' => $id]);
    }

    public function delete($id)
    {
        return $this->db->delete('users', ['id' => $id]);
    }
}

In the above code, we first introduced the Medoo framework and configuration files. Then a User class is created, whose constructor is used to initialize the database connection and pass the $config array as a parameter to the Medoo instance.

Each method in the User class corresponds to a database operation. For example, the getAll method is used to obtain all user information, the getById method is used to obtain individual user information based on id, the add method is used to add new user information, the update method is used to update existing user information, and the delete method is used to delete the specified user information. User Info.

4. Using model classes

It is very simple to use the User model class in your program. Just create a User object and call the methods in it.

<?php

require_once 'User.php';

$user = new User();

// 获取所有用户信息
$users = $user->getAll();
print_r($users);

// 根据id获取单个用户信息
$user = $user->getById(1);
print_r($user);

// 添加新的用户信息
$data = [
    'username' => 'test',
    'password' => '123456'
];
$user->add($data);

// 更新现有用户信息
$data = [
    'username' => 'new_test',
    'password' => '123456'
];
$user->update(1, $data);

// 删除指定用户信息
$user->delete(1);

In the above code, we first create a User object. Then use this object to call the getAll method to obtain all user information, the getById method to obtain the user information of the specified id, the add method to add new user information, the update method to update the user information of the specified id, and the delete method to delete the user of the specified id. information.

5. Summary

By using the ORM function of the Medoo framework, we can perform database operations more conveniently. Just create a model class and use that class in your program. The Medoo framework supports multiple types of databases and can be configured according to actual conditions. In actual development, we can extend the methods of the model class according to our own needs to make it more consistent with actual business needs.
