Answer 1

Just adding onto @Alec's answer.

There is a parse_url() function:

Which can return fragment - after the hashmark #. However, in your case it will return all values after the hashmark:

Array
(
    [path] => catalog.php
    [fragment] => album=2song=1
)

As @NullUserException pointed out, unless you have the url beforehand this really is pointless. But, I feel its good to know nonetheless.
