Connecting MySQL to PHP?

Question

PHP

I write in PHP file:
$link = mysqli_connect('127.0.0.1', 'root', '123456', 'php_db');

On startup it gives an error:
Warning: mysqli_connect(): (HY000/1045): Access denied for user 'root'@'localhost' (using password: YES) in C:\Openserver\...\index.php on line 26

perhaps this is due to the fact that I installed openserver and when I try to enable the mysql module, it gives an error: It is impossible to take port 3306 because it is already in use: c:\program files\mysql\mysql server 8.0\bin\mysqld.exe The only way

to solve the problem is to demolish installed mysql and use built-in openserver? Or are there other solutions?

Answer 1

Well, you have two muscles who want to occupy one port, you can change the port of the muscle in the settings in the open server, if you want to connect to the open server muscle, then use the port that you set and write in the connection
