PHP MySQL 插入多條記錄
使用 MySQLi 和 PDO 插入多條記錄到 MySQL
必須使用 mysqli_multi_query() 函式執行多個 SQL 語句。
以下示例向 "MyGuests" 表新增三條新記錄
示例（MySQLi 面向物件）
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// 建立連線
$conn = new mysqli($servername, $username, $password, $dbname);
// 檢查連線
if ($conn->connect_error) {
die("連線失敗: " . $conn->connect_error);
}
$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', 'john@example.com');";
$sql .= "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('Mary', 'Moe', 'mary@example.com');";
$sql .= "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('Julie', 'Dooley', 'julie@example.com')";
if ($conn->multi_query($sql) === TRUE) {
echo "新記錄建立成功";
} else {
echo "錯誤: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
請注意，每個 SQL 語句都必須以分號分隔。
示例（MySQLi 過程式）
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// 建立連線
$conn = mysqli_connect($servername, $username, $password, $dbname);
// 檢查連線
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', 'john@example.com');";
$sql .= "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('Mary', 'Moe', 'mary@example.com');";
$sql .= "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('Julie', 'Dooley', 'julie@example.com')";
if (mysqli_multi_query($conn, $sql)) {
echo "新記錄建立成功";
} else {
echo "錯誤: " . $sql . "<br>" . mysqli_error($conn);
}
mysqli_close($conn);
?>
PDO 的方式略有不同
示例（PDO）
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDBPDO";
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
// 將 PDO 錯誤模式設定為異常
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// 開始事務
$conn->beginTransaction();
// 我們的 SQL 語句
$conn->exec("INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', 'john@example.com')");
$conn->exec("INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('Mary', 'Moe', 'mary@example.com')");
$conn->exec("INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('Julie', 'Dooley', 'julie@example.com')");
// 提交事務
$conn->commit();
echo "新記錄建立成功";
} catch(PDOException $e) {
// 如果出現任何錯誤，則回滾事務
$conn->rollback();
echo "錯誤: " . $e->getMessage();
}
$conn = null;
?>
