我正在創建實體（實體 - 視圖 - 控制器）（換句話說，模型的MVC）類理論上匹配數據庫表我有。有沒有一種工具讀取mysql表並創建模型類代碼？ （不是在執行時，需要代碼輸出） 我希望像PHP實體類生成器
class{
public $columnname1;
public $columnname2;
public $columnname3;
public $columnname4;
public $columnname5;
public $columnname6;
function __construct(&$columnname1, &$columnname2){...}
function insert(&$columnname1, &$columnname2){}
function delete(&$columnname1){}
...
}
一個工具，它也將創建插入，更新和ID刪除功能將幫助我很多的輸出。
該工具可以免費或付費。
PDO可以fetch results into an object。
設計一個與您的數據庫/查詢結構相匹配的類，並使用錯誤的問題，我的壞。PDO::FETCH_INTO將結果集提取到已經實例化的對象中。
爲了從數據庫結構類本身，有幾個項目（我沒有測試過，但這次來到了一個非常簡單的搜索）。
我正在尋找一種能夠自動完成的解決方案，因爲它可以自動完成。我知道如何去做所有這些，比如認識數學和購買計算器 – 2012-04-13 22:49:18
等等，你想從表中生成類？ – 2012-04-13 22:50:20
是的，就像問題 – 2012-04-13 22:53:56
什麼？它完全符合你的說法，並且你會得到一個非常好的框架。
symfony根據您提供的數據模型爲您編譯類。它將確保編譯的類和MySQL數據庫結構是同步的。
這種方法比基於Reflection的方法有利，因爲它太簡單了。
是的，原則是你所需要的。
運行命令，你會得到所有的表的元數據以XML或YML格式（選擇是你的）
$ PHP應用程序/控制檯學說：映射：轉換XML ./src/ Bundle/Resources/config/doctrine/metadata/orm --from-database --force
一旦你生成元數據，命令Doctrine導入架構來構建你需要的相關實體類。你會發現所有的GET和SET功能（閱讀選擇,更新和INSERT）裏面。
1 $的PHP應用程序/控制檯學說：映射：進口包註釋
2. $ PHP應用程序/控制檯學說：生成：實體捆綁
「在」doctrine：mapping「命名空間中沒有定義任何命令。」 – Scott 2016-11-21 18:02:33
Fat free framework讓你使用以下代碼與現有表一起工作：
$user=new DB\SQL\Mapper($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();
上面的代碼創建新記錄用戶表
下面的代碼是我用了很長時間來創建MySQL和DB2表的PHP模型。我有MSSQL，PGSQL和SQLite的存根，但從來沒有需要完成它們。
下面的代碼生成器類：

對於它的價值，Rafael Rocha股票代碼here。
儘管如此，我強烈推薦使用ORM的。將MySQL結構轉換回數據庫抽象層是一件不錯的事情...
我認爲你應該讓它變成你的。我認爲每個項目和模型代碼的要求是不同的。兩個mysql查詢會讓你放心。
SHOW TABLES FROM db_NAME //this gives the table listing, so its Master LooperDESC tbl_name //detail query that fetches column information of given tableDESC tbl_name會給字段中，鍵入，空，重點，默認和額外的列。
例如在管道（|）中分開的值：
Id | int（11）| NO | PRI | NULL | auto_increment |
我遵循這些規則來製作支持Codeigniter 2中的CRUD操作的Model，控制器和查看器文件。它工作得很好。
我寧願自動生成基本知識並操作 – 2013-02-21 09:29:49
是的，如果您已經建立了標準，那麼完全基本的CRUD總是相似的。我想我的代碼不清楚，但問題是，這兩個查詢會給你表格列信息，這可以用來生成MVC類和文件。 – 2013-02-21 09:50:23
我已經寫了一個PHP代碼，它會自動檢測MYSQL數據庫中的所有數據庫，在選擇任何數據庫時，它的所有相關表都被加載。您可以選擇所有表格或任何相應的表格來生成模態類別。
以下是鏈接到我的倉庫
https://github.com/channaveer/EntityGenerator
這會自動創建實體目錄和轉儲所有的實體類到該文件夾。
注 - 目前僅支持MYSQL
希望它有幫助。快樂編碼！
試試這個 https://github.com/rcarvello/mysqlreflection
一個有用的工具我爲MySQL數據庫的對象關係映射。
該實用程序爲給定數據庫模式的任何表自動生成PHP類。
