Design pattern for implementing plugins in PHP applications

Question

Is there a consensus on how plugins should be implemented in a PHP application?

I\'ve looked into the observer pattern which comes close, it\'s really just a notificati

Answer 1

There is no consensus as in the Silver Bullet sense. For established patterns, you have multiple options like

• Subject/Observer,
• Signal Slot,
• Event Dispatcher or
• Pipes and Filters

to name a few.

Which you use is up to you, but you should make sure your system architecture supports the modularity. Have a look at these slides for some ideas
