<?php

    protected static $handle; //单例句柄 
 
 
    protected $table; 
 
    protected function \_\_construct() \{ 
        $this->table = $this->\_table('biz\_log'); 
    \} 
 
    /\*\* 
     \* 获取本类单例的方法,公开 
     \* 
     \* @return MBizLog 
     \*/ 
    public static function instance() \{ 
        if(self::$handle)\{ 
            return self::$handle; 
        \} 
 
        $class = \_\_CLASS\_\_; 
        self::$handle = new $class(); 
        return self::$handle; 
    \} 
 
    /\*\* 
     \* 商家管理时调用的日志插入 
     \* 
     \*/ 
    static public function addLog($msg) \{

所有模型都继承SModel类

模型类名以M开头

前两个属性与前两个方法是固定写法  , 请修改其中与具体表相关的词(包括注释中)

之后是各种模型方法

注意,模型是单例的,调用时需要 MProduct::instance()->xxx()

* 基类已经实现的模型方法
