How does a Callback look like in action in codding how can I spot a callback?

Is a call back a method or a piece of code in PHP? So confused how this look like I already know what it is but nobody is good at spotting it in examples just saying and I still don't know what it useful for.

So you already know what it is, but then you say you don't know what it's useful for. I don't understand your question. Please rephrase it if possible.
