What is Drip?
Drip is an Inversion of Control (IoC) container written in PHP4 and inspired by
Copland. In a nutshell, it allows you
to simplify the instantiation and initialization of your classes.
Inversion of Control, also known as
IoC, is a relatively new concept that
has been made popular by the Spring
Application Framework and can be used to reduce coupling inherent in
computer programs. As Martin Fowler
points out, the
term 'Inversion of Control' is a poorly-chosen one. Still, it is the one that
most people know the concept by, so it will be used throughout the
As of now there are no other IoC
containers for PHP4 beside Drip.
What can Drip do for you?
Ultimately, it can reduce the amount of code that you have to write, simplifying
some common programming tasks for you. This has the two-fold benefit of both
decreasing application development time, and of decreasing the effort needed to
maintain your application.
Specifically, Drip features:
- Reference Another Service
- Service Configuration
