Can anyone help with Script link "Callbacks"?

[AreYouAMac]

Hello,

I'm beginning to learn about PHP Scripts. I saw the term "callback" on Google on a couple of websites, but there weren't any good info on what it is.

I think I should clarify on link callbacks

If I am understanding correct, callbacks are just links that link back to the original developer? Can they be automatic or does the user have to request it (i.e. pushing a link button).

Can the callback be encrypted or are they only a few codes that will allow callbacks?

Thanks!

Whether it's secure or not depends on if the source is using https for the URL. Callbacks are just functions that get called after some process. These are often used with AJAX calls that go to the server, then when the call is done you may have a callback setup to run using that data returned from the AJAX call. They can vary a bit though, so you'll need to be more specific with your situation if you want specific help.
