Need Help setting Global Varriables

Hi, I'm new to Php programming so forgive me if this is a noob question.

 

Right now in my PHP scripts I'm using the actual name of database, host,  username and password to connect to MySql database. Is there a way in which I can set all these values to a variable in one place like we do in C++ iusing #define and use that variable everywhere I need it?. So that in case any change occurs I won't have to look for them everywhere and change them individually.

I know there must be a way to do this. Can you please point me in any direction?

 

Thanks in advance
