我做错了什么？出于安全目的，HostGator将默认拒绝您对数据库的连接请求 您需要将ip地址添加到远程数据库访问主机列表中 以下是一个屏幕截图，以备您需要：
您可以使用或作为api连接到数据库： 以下是PDO中的一个示例：
$dbh = new PDO('mysql:host=localhost;dbname=test', $user, $pass);
$query ='SELECT * FROM post_data WHERE type=:type ORDER BY id DESC LIMIT 15';
$stmt = $dbh->prepare($query);
if ($stmt->execute(array(':type'=>'mixtape'))) {
$json = array();
while ($row = $stmt->fetch()) {
$json[] = $row;
}
echo json_encode($row);
}
现在，您的应用程序负责向该脚本发出请求并解码JSON数据。看起来您没有用户
