我正在尝试通过使用$db=null;关闭每个脚本来解决此问题，但是它似乎不起作用.
I am trying to solve this issue by closing every script by using $db=null; but it doesn't seem to work.
我联系了服务提供商.他们说一切正常.您需要在最后检查错误.我只有几个用户.
I contacted the service provider. They say everything works fine. You need to check errors at the end. I have just a few users.
为什么有时会出现此错误?
Why do I somestimes get this error?
我的托管不受限制:磁盘空间不受限制.无限带宽，但仍然出现此错误.我不知道该如何解决这个问题.我希望扩大我的网站，但这些错误使我感到困惑
My hosting is unlimited: unlimited disk space. unlimited bandwidth but still I get this error. I don't know how can I solve this issue. I hope to make my website larger but these error make me confuses
我的db.php文件具有此代码.你可以检查一下吗?也许这是造成问题的原因.
My db.php file has this code. Can you check if this fine? Maybe this is causing the problem.
db.php
$db = new PDO('mysql:host=localhost;dbname=mobiles;charset=utf8', 'root', '**somePassword**');
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
推荐答案
您的连接代码没有错.
在共享主机上，无限制"表示其他用户不受资源使用限制.意味着他们可以吃饱整个游泳池，而您的消费却保持适度.
On a shared hosting, "unlimited" means other users are unrestricted with their resource using. Means they can eat up whole pool, while your consumption remains modest.
您已经在评论中被告知，请不要使用该主机.
As you've been told in comments, don't use this host.
