yaf集成medoo简单轻便操作数据库

第一步：打开yaf命名空间

第二步：安装medoo

composer require catfan/medoo

第三步：自动加载

public function _initLoad()
    {
        Yaf\Loader::import(APPLICATION_PATH . '/application/vendor/autoload.php');
    }

第四步：连接数据库

public function _initDatabase()
    {
        $arrConfig = Yaf\Registry::get('config');
        $option    = [
            'database_type' => $arrConfig->database->database_type,
            'database_name' => $arrConfig->database->database_name,
            'server'        => $arrConfig->database->server,
            'username'      => $arrConfig->database->username,
            'password'      => $arrConfig->database->password,
            'prefix'        => $arrConfig->database->prefix ?? '',
            'charset'       => $arrConfig->database->charset ?? 'utf8',
            'logging'       => $arrConfig->database->logging,
            'option'        => [
                PDO::ATTR_CASE => PDO::CASE_NATURAL,
            ],
        ];
        Yaf\Registry::set('db', new \Medoo\Medoo($option));
    }

第五步：在模型里面使用数据库连接

<?php

/**
 * @name SampleModel
 * @desc sample数据获取类, 可以访问数据库，文件，其它系统等
 * @author admin
 */
class UserModel
{
    private $db;
    private $table = 'users';

    public function __construct()
    {
        $this->db = Yaf\Registry::get('db');
    }

    function list() {
        $users = $this->db->select($this->table, ['id', 'name']);
        return $users;
    }
}
