Make a Config file to connect to MySql Database

In order to connect to a database you need to make a key file. Make a Config file to connect to MySql Database. This is a fairly simple process. You take the information that you assigned to a database when you granted privileges to it and make a  file and call it config.php. You can call the file whatever you want what is important is that you have the right login information to the database. Some people call their key file common.php or key.php.

Here is the code that you will need for our examples that we will be doing in php. Put this code in your config.php file that you created with your FTP program..
