Nice music .

Excellent. Thank you!

Thank you, you helped me

getting this warning

Warning: mysqli_connect(): (HY000/1049): Unknown database 'train' in /opt/lampp/htdocs/connect.php on line 6
Error Connecting

after going to connect.php file with editor mode in 6th line what the details we have to provide?

$connect = mysqli_connect($hostname , $username , $password ,$dbname) or die("Error Connecting");

Try changing the database name.This error occur when many people are using the same name on MYPHPADMIN.Use a unique name.
DONT NAME DATABASE THIS WAY: food-order
NAME IT THIS WAY: food_order
Thank me later.

Hey! Both my names in "connection" file and PHPMyAdmin are the same. But I'm still facing the same issue. HELP

Warning: mysqli_connect(): (HY000/1049): Unknown database 'polltest' in C:\xampp\htdocs\voting\connection.php on line 2

You are such a life saver man. thanks

I still got an error message about UNKOWN DATABASE. This is how I fixed it....

Remove $db from the $conn line and hit save. My database was immediately connected.

Check my.ini file of mysql and verify port number. Im most of the cases it runs on 3306 however if it is running on 3308 then edit your connection file:
$conn = mysqli_connect($server_name, $mysql_username, $mysql_password, $db_name, "3308");

Спасибо огромное! После этого видео я решила переехать в Пакистан, видимо только тут способны помочь сделать лабы!!!!

If anyone still getting error then try to create db in MariaDB once and then try. It resolve my error as it check db in MariaDB instead of MySql

I'm having this problem almost 3 weeks can't fix till now.. 😭

my database name is right but it keeps saying Y000/1049): Unknown database 'pendaftaran' in C:\wamp64\www\pendaftaran\server.php on linY000/1049): Unknown database 'pendaftaran' in C:\wamp64\www\pendaftaran\server.php on line 7

thanks vi

I'm still having the same problem after doing this. Ive double checked it already. I'm using the same db name and unknown database is still there

I don't see how this is helpful. You just created the database and error showed up because you didn't have it earlier. What about when this error is showing up even after i've created the database and checked it seperately using cmd too?

This is amazing u saved my life

thank you

that is actually working, I was actually stuck in that and I was about to quit programming due to it. u helped me thank u !!
