I think you're approaching this the wrong way.
1) have a clear understanding of PHP - syntax, capabilities, etc.
2) have a clear understand of what you're intending to do -
application's function/purpose, features, manageability,
expandability, portability, etc...
3) understand design patterns

What your asking is practically impossible in any programming language
akin to 'how to un-import packages in Java' or 'how to un-using
namespace in C#'.  If you don't want to use it, don't include it ;)
If this is running as web app, you can use header [1] and pass the
criteria for next phase of the operation as URL parameters.  But doing
this is going to kill the server side with too many unnecessary round
trips.  Which clearly demonstrates point 2 and 3.  You should look
into Interfaces, and Abstract under OOP [2].
