First change this database connection, and don't use mysql beacause is deprecated use mysqli instead. 首先更改此数据库连接，并且不使用mysql，因为不建议使用mysqli。
<?php
// host, user, password, database name
$conn = mysqli_connect("localhost", "root", "", "login");
// if u use mysql then ur connection need to connect first then select database
// $conn = mysql_connect("localhost", "root", "");
// $db = mysql_select_db("database name");
if (!$conn) {
die("Connection faile: " . mysqli_connect_error());
}
?>

use mysqi because it is more secured and you only need to adjust mostly on parameters but better if you start using it, mysql is deprecated already so try to avoid using mysql functions and start using mysqli.. connect using this 使用mysqi是因为它更加安全，您只需要在参数上进行大部分调整即可，但是如果您开始使用它，则更好，因为mysql已经过时了，因此请避免使用mysql函数并开始使用mysqli。
$db_host = '192.168.1.9'; //sample
$db_user = 'dbuser'; //sample usename
$db_pass = 'dbpass'; //sample password
$db_name = 'databasename';
$db = mysqli_connect($db_host, $db_user, $db_pass, $db_name);
if(mysqli_connect_errno($db))
die('Failed to connect to MySQL: ' . mysqli_connect_error());
hope this helps. 希望这可以帮助。
