PHP连接MySQL错误

Question

I keep on getting this error : Warning: mysqli_connect(): (HY000/1045): Access denied for user '12345'@'localhost' (using password: YES). I have already tried to create a new user, using a password, using no password, granting privileges to new user. I can login to the mysql database using these credentials. I can run every command with them in MySQL, just not connect to PHP. If it matters, this is my php code

<? php 
$dbServername = "localhost";
$dbUsername = "12345";
$dbPassword = "12345";
$dbName = "loginsystem";

$conn = mysqli_connect($dbServername, $dbUsername, $dbPassword, $dbName);

When showing grants for user: '12345'@'localhost':

mysql> SHOW GRANTS FOR '12345'@'localhost';

Oh I forgot to mention I did flush privileges and restarts of server.

Hello @Steven in my experience xampp gives error on Mac (at least in my opinion) so i used MAMP. You can check it if you want. BUT going to the point of ur error this seems to be a connection issue: try this connection code please:

$user = '12345'; 
$password = '12345'; 
$db = 'loginsystem'; 
$host = 'localhost'; 
$port = your_port-might-be-3306; 
$link = mysqli_init(); 
$success = mysqli_real_connect( $link, $host, $user, $password, $db, $port ); 
echo $success;

If the $success variable shows a 1 if the connections is working. If so, then your connection works.
