PHP MySQL 插入多条数据
一般情况下，INSERT 语句只能向 MySQL 数据库添加一条语句，而本文将介绍如何使用函数批量的向数据表插入多条数据。
使用 MySQLi 和 PDO 向 MySQL 插入多条数据
mysqli_multi_query() 函数可用来执行多条SQL语句。
以下实例向 “MyGuests” 表添加了三条新的记录：
实例 (MySQLi – 面向对象)
<?php
$servername = "localhost";
$username = "username";
$password =
"password";
$dbname =
"myDB";
// 创建链接
$conn =
new mysqli($servername, $username, $password, $dbname);
// 检查链接
if ($conn->connect_error) {
die("Connection failed: " . $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 "New
records created successfully";
} else {
echo
"Error: " . $sql . "
" . $conn->error;
}
$conn->close();
?>
 | 请注意，每个SQL语句必须用分号隔开。 |

实例 (MySQLi - 面向过程)
<?php
$servername = "localhost";
$username = "username";
$password =
"password";
$dbname =
"myDB";
// 创建链接
$conn = mysqli_connect($servername, $username, $password,
$dbname);
// 检查链接
if (!$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 "New
records
created successfully";
} else {
echo "Error: "
. $sql . "
" . mysqli_error($conn);
}
mysqli_close($conn);
?>
实例 (PDO)
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname =
"myDBPDO";
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname",
$username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE,
PDO::ERRMODE_EXCEPTION);
// 开始事务
$conn->beginTransaction();
// SQL 语句
$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')");
// commit the transaction
$conn->commit();
echo "New records created successfully";
}
catch(PDOException $e)
{
// roll back the transaction if something failed
$conn->rollback();
echo $sql . "
" . $e->getMessage();
}
$conn = null;
?>
