What does chdir() in PHP actually do?

This might seem like a stupid question but I've looked throught the PHP manual and whatever forum threads are available on the subject (not many) and I don't get what the chdir() function actually does. Does it change your include directory? I guess I don't get how you can change to a different directory than the one you are actually in. I have a fairly decent understanding of programming in PHP, but not so hot on dealing with manipulating directories, paths, etc. and am trying to learn, so please answer as if I don't know anything about it. Thanks
