Propel ProjectPHP5 的 OR 映射框架
Propel是一个适用于PHP5的OR映射(Object Relational Mapping)框架。它允许你使用对象代替SQL来读写数据库表格中的行。Propel提供一个生成器来为你的数据模型创建SQL定义文件和PHP类，与一个运行期引擎用来透明地获取和持久化对象。
示例代码：
<?php
$book = BookQuery::create()->findPK(123); // retrieve a record from a database
$book->setName('Don\'t be Hax0red!'); // modify. Don't worry about escaping
$book->save(); // persist the modification to the database
$books = BookQuery::create() // retrieve all books...
->filterByPublishYear(2009) // ... published in 2009
->orderByTitle() // ... ordered by title
->joinWith('Book.Author') // ... with their author
->find();
foreach($books as $book) {
echo $book->getAuthor()->getFullName();
