我正在创建实体（实体 - 视图 - 控制器）（换句话说，MVC的模型）类，这些类在理论上与我拥有的databse表相匹配。有没有一个工具可以读取mysql表并创建模型类代码？（不是在执行时，需要代码输出）我希望输出如下
class{
public $columnname1;
public $columnname2;
public $columnname3;
public $columnname4;
public $columnname5;
public $columnname6;
function __construct(&$columnname1, &$columnname2){...}
function insert(&$columnname1, &$columnname2){}
function delete(&$columnname1){}
...
}
一个还可以通过id函数创建插入，更新和删除的工具将对我帮助很大。
该工具可能是免费的，也可以是付费的。
PDO 可以将结果提取到对象中。
设计一个与数据库/查询结构匹配的类，并用于将结果集提取到已实例化的对象中。误读了这个问题，我的坏。PDO::FETCH_INTO
要从数据库结构生成类本身，有几个项目（我还没有测试过，但这是在一个非常简单的搜索中出现的）。
下面的代码是我长期以来用来为MySQL和DB2表创建PHP模型的代码。我已经为MSSQL，PGSQL和SQLite设置了存根，但从未需要完成它们。
下面是代码生成器类：
