PHP实体类生成器
我正在创建实体（实体视图控制器的）（换句话说，MVC的模型）类，这些类在理论上与我拥有的数据库表相匹配。是否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） 我希望输出像PHP实体类生成器,php,mysql,oop,Php,Mysql,Oop,我正在创建实体（实体视图控制器的）（换句话说，MVC的模型）类，这些类在理论上与我拥有的数据库表相匹配。是否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） 我希望输出像 class{ public $columnname1; public $columnname2; public $columnname3; public $columnname4; public $columnname5; public $columnname6; function __const

function insert(&$columnname1, &$columnname2){}
function delete(&$columnname1){}
...
}
反射的方法，因为它太慢了。PDO可以
设计一个与数据库/查询结构匹配的类，并使用PDO:：FETCH_INTO
将结果集提取到一个已经实例化的对象中。误读了这个问题，我的错
要从数据库结构生成类本身，有几个项目（我还没有测试，但这是一个非常简单的搜索）
我知道你在找ORM之类的东西
希望这有帮助
是的，教条是你需要的
- 运行一个命令，您将获得XML或YML格式的所有表元数据（由您选择）
$php应用程序/控制台原则：映射：转换xml./src/Bundle/Resources/config/doctor/metadata/orm--from数据库--force
- 生成元数据后，命令导入模式以构建所需的相关实体类。您将在其中找到所有获取和设置功能（阅读选择、更新和插入）
1.$php应用程序/控制台原则：映射：导入包注释
2.$php应用程序/控制台原则：生成：实体包
允许您使用以下代码处理现有表：
$user=new DB\SQL\Mapper($db,'users');
// or $user=new DB\Mongo\Mapper($db,'users');
// or $user=new DB\Jig\Mapper($db,'users');
$user->userID='jane';
$user->password=md5('secret');
$user->visits=0;
$user->save();
上面的代码在users表中创建了新记录，下面的代码是我很长时间以来用来为MySQL和DB2表创建PHP模型的代码。我已经准备好了MSSQL、PGSQL和SQLite的存根，但从未需要完成它们

为了它的价值，分享代码
不过，我强烈建议使用ORM。将MySQL结构转换回数据库抽象层一点也不好…我认为您应该在自己的基础上进行改进。在我看来，模型代码的每个项目和要求都是不同的。两个mysql查询将使您轻松
SHOW TABLES FROM db\u NAME//这给出了表列表，因此它的主循环器
DESC tbl\u name//获取给定表的列信息的详细查询
DESC tbl_name
将给出字段、类型、空值、键、默认值和额外列
e、 g.管道（|）中分开的值：
Id | int（11）| NO | PRI | NULL |自动增量|
我按照这些方法制作了支持Codeigniter 2中CRUD操作的模型、控制器和查看器文件。它工作得很好。我已经编写了一个PHP代码，它将自动检测MYSQL数据库中的所有数据库，在选择任何一个数据库时，它的所有相关表都将被加载。您可以选择所有表或任何相应的表来生成模态类
以下是指向我的存储库的链接
这将自动创建实体文件夹，并将所有实体类转储到该文件夹中
注意-目前仅支持MYSQL
希望能有帮助。快乐编码 试试这个
我为MySQL数据库的对象关系映射构建了一个有用的实用程序
该实用工具自动为给定数据库模式的任何表生成PHP类
该软件包是从我的个人PHP Web MVC框架中提取的。我正在寻找一个自动完成该功能的解决方案，因为它可以自动完成。我知道如何做所有这些，比如懂数学和买计算器等等，你想从表中生成类吗？是的，就像我在使用netbeans的问题中所说的，我想我现在试试db2ppp，看起来很有用还有另一种方法，签出。还有一个类似的，但也有，这可能就是你要找的：。这可能很有趣：。但该功能仍然是实验性的。@mogria我希望导出的文本文件（php或其他）作为输出。强烈建议您采用另一种方法：首先设计您的模型，然后，您的数据访问和数据库表应该基于模型。@NazarMerza是什么让这不仅仅是个人偏好？我宁愿自动生成基本数据并处理我的数据。是的，如果您已经建立了标准，基本CRUD总是相似的。我想我的行不清楚，但重点是，这两个查询将为您提供表列信息，这可以用来生成MVC类和文件。您还可以共享base_mysql类吗？@Grynn-base_mysql
类超过700行，它的父类（base
）大约有650行。我很乐意把它们发电子邮件给你或别的什么。电子邮件会很棒的（vishal）。doshi@gmail.com)或者您可以将其粘贴到gist.github.com。我很乐意用您的代码（当然是您的代码）制作一个github或任何项目-因此它是可维护的…@Grynn-电子邮件已经发送。您好，我很高兴收到这个@clashnco@gmail.com“条令：映射”命名空间中未定义任何命令
