## MySQL 創建數據庫 ### 面向對象 ```php $sql = "CREATE DATABASE myDB"; if ($conn->query($sql) === TRUE) { echo "Database created successfully"; } else { echo "Error creating database: " . $conn->error; } $conn->close(); ``` ### 面向過程 ```php $sql = "CREATE DATABASE myDB"; if (mysqli_query($conn, $sql)) { echo "Database created successfully"; } else { echo "Error creating database: " . mysqli_error($conn); } ``` ### PDO ```php try { $sql = "CREATE DATABASE myDBPDO"; // 使用 exec() ，因為沒有結果返回 $conn->exec($sql); echo "Database created successfully<br>"; } catch(PDOException $e) { echo $sql . "<br>" . $e->getMessage(); } ```
