Problem with connectivity with mysql database

[Abdo_Saad]

I uploaded the php file to host 000webhost As in this picture.

But the problem isn’t here. I want to get this file link, but I can’t In this picture, the link to the page from which the link is obtained, and it shows me like this.

But when someone else shows up like this.

You could know what’s wrong here.

The page you are see is index.php or index.html page by default in public html folder.
Your path to script is.
Yourdomain/mysql.php
Eg.
www.example.com/mysql.php
