在YII中对合并数组进行排序

Question

public function actionIndex() { 
    $sales = Sale::model()->findAll(); 
    $news = News::model()->findAll(); 

    $merged = CMap::mergeArray($sales, $news); 

    $this->render('index', array(
     'merged ' => $merged 
    )); 
} 

如何对任何字段（例如创建的字段）合并的$进行排序？

想一想使用join。但是你可以用这样的方式（我不知道你的条件）：

$union = Yii::app()->db->createCommand() 
     ->select('created') 
     ->from(Sale::model()->tableName()) 
     ->order('created ASC') 
     ->getText(); 

$command = Yii::app()->db->createCommand() 
     ->select('created') 
     ->from(News::model()->tableName()) 
     ->union($union) 
     ->order('created ASC'); 

echo '<pre>'; 
print_r($command->queryAll()); 
echo '</pre>'; 
die(); 
//or 
$dataReader = $command->query(); 
foreach($dataReader as $row) { ... } 

UNION

JOIN
