代码如下:


/** 
    * 插入insertModel(),利用反射,效率稍差
    * @param class $model 对象
    * @param bool $is_returnLastInsertId 是否返回添加ID
    * @return int 默认返回成功与否,$is_returnLastInsertId 为true,返回添加ID
    */
    public function insertModel($model,$is_returnLastInsertId=FALSE) {
        try {
            require_once dirname(dirname(__FILE__)).'\Models\BaseModel.php';
            if(!is_subclass_of($model, "BaseModel")){
                exit($this->getError(__FUNCTION__, __LINE__));
            }
            $className=get_class($model);
            $tName = $this->formatTabName($className);
            $reflectionClass=new ReflectionClass($className);
            $properties=$reflectionClass->getProperties();
            unset($properties[0]);
            $fields="";
            $vals="";
            foreach ($properties as $property) {
                $pName=$property->getName();
                $fields.=$pName.",";
                $vals.='\''.$model->$pName.'\''.',';
            }
            $fields=rtrim($fields,',');
            $vals=rtrim($vals,',');
            $this->sql = "insert into {$tName} ({$fields}) values ({$vals})";
            if($is_returnLastInsertId){
                $this->conn->exec($this->sql);
                $lastId = (int)$this->conn->lastInsertId();

                return $lastId;
            }  else {
