MySQL只在php foreach循环中插入几行

<?php
// 连接到MySQL数据库
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";

$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 待插入的数据
$data = array(
    array("John", "Doe", "john@example.com"),
    array("Jane", "Smith", "jane@example.com"),
    array("Bob", "Johnson", "bob@example.com")
);

// 使用foreach循环插入数据
foreach ($data as $row) {
    $sql = "INSERT INTO users (first_name, last_name, email) VALUES ('" . $row[0] . "', '" . $row[1] . "', '" . $row[2] . "')";

    if ($conn->query($sql) === TRUE) {
        echo "插入成功<br>";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
}

// 关闭数据库连接
$conn->close();
?>
