Answer 1

parse_url() can get the hash from a url string. Note the signature:

mixed parse_url ( string $url [, int $component = -1 ] )

You must already know the string. For instance, from the docs:

Outputs

Array
(
    [scheme] => http
    [host] => hostname
    [user] => username
    [pass] => password
    [path] => /path
    [query] => arg=value
    [fragment] => anchor
)
/path

Note the entry under key "fragment".
