php - PDO fetchAll 返回数组中的对象或数组中的数组

Question

我有一个烦人的问题，无论我告诉PDO返回一个数组或对象，它总是将它放在另一个数组中。IE。：

Array (
    [0] => stdClass Object ( [name] => Test Topper [urlName] => test-topper )
    [1] => stdClass Object ( [name] => Test Topper [urlName] => test-topper )
    [2] => stdClass Object ( [name] => adfg dfg [urlName] => adfg-dfg ) 
    [3] => stdClass Object ( [name] => adfg dfg [urlName] => adfg-dfg )
)

我该如何停止这种行为，所以我最终得到：

stdClass Object ( [name] => Test Topper [urlName] => test-topper ) 
[1] => stdClass Object ( [name] => Test Topper [urlName] => test-topper )
[2] => stdClass Object ( [name] => adfg dfg [urlName] => adfg-dfg ) 
[3] => stdClass Object ( [name] => adfg dfg [urlName] => adfg-dfg )

所以我可以使用$data->name而不是访问属性$data[0]->name？

这是负责获取数据的 PHP：

public function fetchToppersAction($type, $orderBy, $limit)
{
    $PDOParams = array() ;
    $SQL = 'SELECT name, urlName FROM toppers_images, toppers
            LEFT JOIN meta_descriptions AS md ON md.topperId = toppers.id
            ' ;
    if($type)
    {
        $SQL .= 'WHERE typeId = ?' ;
        array_push($PDOParams, $type) ;
    }
    $SQL .= 'ORDER BY ? LIMIT ?' ;
    array_push($PDOParams, $orderBy, $limit) ;

    $r = $this->db->prepare($SQL) ;
    $r->execute($PDOParams) ;
    return $r->fetchAll(PDO::FETCH_OBJ) ;
}

Answer 1

这种方式是不可能的。。

你怎么能叫$data->namewhgen 你有多个名字？

而不是这样做

   /* 
    * $dataArray is the array which you are getting from $r->fetchAll(PDO::FETCH_OBJ);
    *
    */

  foreach($dataArray as $data){
    echo $data->name;
   }
