php怎么增加多行数据？
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("连接失败: " . $conn->connect_error);
}
$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', '[email protected]');";
$sql .= "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('Mary', 'Moe', '[email protected]');";
$sql .= "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('Julie', 'Dooley', '[email protected]')";
if ($conn->multi_query($sql) === TRUE) {
echo "新记录插入成功";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
Note 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("连接失败: " . mysqli_connect_error());
}
$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', '[email protected]');";
$sql .= "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('Mary', 'Moe', '[email protected]');";
$sql .= "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('Julie', 'Dooley', '[email protected]')";
if (mysqli_multi_query($conn, $sql)) {
echo "新记录插入成功";
} else {
echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}
mysqli_close($conn);
?>
