Is it possible to have href link refer to same PHP file?

Is there a way to have an ordinary href link call some javascript and say "are you sure blah blah blah?" and then once you hit Ok it calls the same php file which then does all the database stuff? I know I can do this just by creating another PHP file and having the link call that, but it seems like it would be nicer to have this in the same file.
