相当于Rails'；简单的ActiveRecord查找功能 - PHP PEAR/DataObject equivalent to Rails' easy ActiveRecord finding functionality

PHP PEAR/DataObject equivalent to Rails' easy ActiveRecord finding functionality

在Rails中，比如说一个博客应用程序，给定一个特定的帖子对象，你可以得到帖子作者的名字，比如：

post = Post.find(1)    
author_name = post.author.name

有没有使用DataObject的PHP等价物，类似于（这里只是虚构的语法）：

$postsTable = DB_DataObject::factory('posts');
$authorName = (($postsTable->id = 1)->find(true))->author->name;
              |  finds and autofetches post #1  |->author->name

如果你想要一个像这样带有API的ORM，我建议你使用PHP ActiveRecord:

$posts = Post::find('all', array('limit' => 10, 'include' => array('author')));
foreach ($posts as $post) {
   echo $post->author->first_name;
}

您可能还对Propel ORM:感兴趣

$book = BookQuery::create()
  ->useAuthorQuery()
    ->filterByFirstName('Leo')
  ->endUse()
  ->with('Author')
  ->findOne();
$author = $book->getAuthor();

DB_DataObject没有流畅的接口，因此无法进行链接。但是你可以这样做：

$postsTable = DB_DataObject::factory('posts');
if($postsTable->get($id)) {
  $authorname = $postsTable->getLink('author_id')->name;
}
