PHP/MySQL - UPDATE查询插入新记录，而不是更新记录

INSERT INTO table_name (column1, column2, column3, ...)
VALUES (value1, value2, value3, ...);

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 准备要插入的数据
$name = "John Doe";
$email = "johndoe@example.com";

// 构建INSERT语句
$sql = "INSERT INTO users (name, email) VALUES ('$name', '$email')";

// 执行INSERT语句
if ($conn->query($sql) === TRUE) {
    echo "新记录插入成功";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

// 关闭连接
$conn->close();
?>
