PHP MySQL 插入多条数据

<?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', '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 "新记录插入成功";
} else {
    echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}
  
mysqli_close($conn);
?>或者以下方法： 1 <?php
 2 $servername = "localhost";
 3 $username = "root";
 4 $password = "123456";
 5 $dbname = "root";
 6  
 7 // 创建链接
 8 $conn = mysqli_connect($servername, $username, $password, $dbname);
 9 // 检查链接
10 if (!$conn) {
11     die("连接失败: " . mysqli_connect_error());
12 }
13  
14 $sql = "INSERT INTO ge222 (firstname, lastname, email)
15 VALUES ('John', 'Doe', 'john@example.com'),('Mary', 'Moe', 'mary@example.com'),('Julie', 'Dooley', 'julie@example.com')";
16  
17 if (mysqli_multi_query($conn, $sql)) {
18     echo "新记录插入成功";
19 } else {
20     echo "Error: " . $sql . "<br>" . mysqli_error($conn);
21 }
