这是我的私人服务器realmeye http://www.thenoxusproject.org/realmeye/index.php的代码 我一直收到这个错误，我不知道如何修复它，请帮忙吗？
致命错误：在第112行的/home/noxus/public_html/realmeye/index.php中调用非对象的成员函数query（）

答案 0 :(得分：8)
如果你注意到，1）你的脚本中没有connect_db()，2）你的功能正在创建$pdo但仍然返回$db，所以即使你使用connect_db()它什么都不会回报：
function connect_db()
{
$pdo = new PDO('mysql:host='.HOST.';dbname='.DB,USER,PASS);
// You need to return $pdo not $db
return $pdo;
}
编辑：由于您可能在整个页面中使用或未使用该连接，因此您可能需要在顶部创建您的功能并将其输入您正在使用的任何功能，特别是此部分： $accounts = $type == 'all' ? get_accounts() : get_accounts();
顺便说一句，这个三元组没有任何意义，无论如何都要在true或false分配函数：
// You are saying if 'all', use 'get_accounts()' but if not 'all' use it 'get_accounts()' as well...
$accounts = $type == 'all' ? get_accounts() : get_accounts();
要修复，只需执行：
$con = connect_db();
$accounts = get_accounts($con);
我注意到您在页面上使用$pdo，因此您可能希望更改为$pdo：
$pdo = connect_db();
$accounts = get_accounts($pdo);
答案 1 :(得分：2)
你需要这样做：
$pdo = connect_db()
之后才能使用$pdo变量。
您还需要修复connect_db()，以便返回它指定的相同变量。
答案 2 :(得分：1)
connect_db()，因此您的$ pdo变量保持未初始化状态。当您第一次调用$pdo->query()时，PHP会抱怨$ pdo不是对象。
