quick question about xml

[Ninjakreborn]

In php, it has a whole set of built in xml handlers, and parsers, and functions.

There is an attribute to one called, call back.

It's on a lot of them but that's just one example

I have tried to locate the definition of the word in relation to PHP, or what this specifically means, I have see it on a few functions.  Any help (or links to the correct usage of the word in relation to php, and this purpose), would be appreciated.
