## 插入數據 ### 面向對象 ```php $sql = "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('John', 'Doe', 'john@example.com')"; if ($conn->query($sql) === TRUE) { echo "New record created successfully"; } else { echo "Error: " . $sql . "<br>" . $conn->error; } ``` ### 面向過程 ```php $sql = "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('John', 'Doe', 'john@example.com')"; if (mysqli_query($conn, $sql)) { echo "New record created successfully"; } else { echo "Error: " . $sql . "<br>" . mysqli_error($conn); } ``` ### PDO ```php try { $sql = "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('John', 'Doe', 'john@example.com')"; // use exec() because no results are returned $conn->exec($sql); echo "New record created successfully"; } catch(PDOException $e) { echo $sql . "<br>" . $e->getMessage(); } ```
