Error while running mysql and .php on web server

[Jian0203]

H, everyone. I'm totally new to MySQL and php. I took few hours to figure out how to use the XAMPP to host a virtual web server. Faced so much problems and luckily, they are solved.

But when I run the .php with my .sql import to a database in phpMyAdmin, the errors displayed in the picture just prompted. I tried to find solution online but it seems i cant find a suitable solution.

Can anyone provide me some helps please?

Thank you so much for spending time to read my problem. Much appreciate if solution can be given

Just in case if you can't see the picture :

Most of this is simply due to poor error handling in the script. It just happily assumes everything is good and keeps going.

Your configurations are simply invalid. Provide a valid server, username, and password to the connection and go from there. There is no way to tell if its invalid beyond that, so you need to fix it up a part at a time.
There sure seems to be a lot of repeating errors here. You're not opening and closing a connection within a loop are you?
