我的本地主機上有一個簡單的數據庫，我正在關注一本書我在其中創建了表，但在使用共享文件地址后，即包括['SERVER_DOCUMENT'].'path of file'對 PHPMyAdmin 的訪問被拒絕。IT 說：無法連接：無效設置。mysqli_real_connect(): (HY000/1130): Host 'localhost' is not allowed to connect to this MariaDB server connection for controluser as defined in your configuration failed. mysqli_real_connect(): (HY000/1130): Host 'localhost' is not allowed to connect to this MariaDB server phpMyAdmin 試圖連接到 MySQL 服務器，服務器拒絕了連接。您應該檢查配置中的主機、用戶名和密碼，并確保它們與 MySQL 服務器管理員提供的信息相對應。我嘗試卸載 XAMPP 但是當我在我的書上再次達到相同的點并從頭開始做所有事情時它仍然做同樣的事情<?phptry {  $pdo = new PDO('mysql:hostname=localhost;dbname=ijdb', 'ijdbuser', 'mypassword');  $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);  $pdo->exec('SET NAMES "utf8"');}catch (PDOException $e) {  $error = 'Unable to connect to server' . $e->getMessage();  include 'error.html';  exit();}?>索引.php<?phpinclude_once $_SERVER['DOCUMENT_ROOT'] .
