$x=parse_url('file:///any/path/file.ext');

gives you:

Array
(
    [scheme] => file
    [host] => /any/path/file.ext
)

$x=parse_url('file://localhost/any/path/file.ext');

gives you:

Array
(
    [scheme] => file
    [host] => localhost
    [path] => /any/path/file.ext
)

the first one is definitively parsed wrong!!! in a file:// url, the 'host' is optional and is located between :// and the first slash.

scheme://[[user[:pass]@]host]/path

so 

$x=parse_url('file:///any/path/file.ext');

*should* give you:

Array
(
    [scheme] => file
    [path] => /any/path/file.ext
)

and nothing else!

btw: have you ever seen a 'host' with slashes? ;-)

btw^2: a 'join_url' (or similar) should be also available (as the counterpart to 'parse_url'). Yes, I know, I can write such function for myself in plain PHP. But there should be always the opposite counterpart available as a native PHP function!

btw^3: not all file-functions are capable to handle file:// urls correctly. I know, that is not your problem... ;-) I will try to find all that functions and create a seperate bugreport.
