给SQL插入当前时间

<?php
//获取数据
$name = $_GET['name'];

$servername = "localhost";    //服务器名
$username = "aaa";    //用户名
$password = "aaa";    //用户密码
$dbname = "bbb";    //数据库名

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

$sql = "INSERT INTO user (name,time)
VALUES ('$name',now())";
 
if ($conn->query($sql) === TRUE) {
    echo "新记录插入成功";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}
//断开连接
$conn->close();

?>
