Question

$db = new PDO( 'mysql:host=localhost;dbname=mydb', 'myusername', 'mypassword' );
$query = $db->query( 'SELECT a.title, a.descrption, a.icon, b.title, b.descrption, b.images
FROM explorefeatures AS a, blog AS b WHERE a.id = b.id' );
while ( $row = $query->fetchAll( PDO::FETCH_ASSOC ) )
{
    //echo "<pre>";
    //print_r($row);
    echo $row->title;
    echo  $row->icon;
    echo $row->images;
    echo $row->descrption;
}

尝试在...中获取非对象的属性

我收到此错误。谁能告诉我代码有什么问题？

FETCH_ASSOC表示：＆＃34;嘿，PDO，获取我关联数组＆＃34;。
关联数组不一个对象。你必须像数组一样访问它：

while ( $row = $query->fetchAll( PDO::FETCH_ASSOC ) )
{
    echo $row['title'];
    echo $row['icon'];
    echo $row['images'];
    echo $row['description'];
}

或者，你可以获取作为对象。你只需要告诉PDO这样做。

while ( $row = $query->fetchAll( PDO::FETCH_OBJ ) )
{
    echo $row->title;
    echo $row->icon;
    echo $row->images;
    echo $row->description;
}

另见：PDOStatement::fetch()

获取记录时出现PDO错误
