Description:
------------
Suggestion for additional FTP functions

ftp_is_dir(), ftp_file_exists(), ftp_is_file().

Currently can be accomplished by

if(!ftp_chdir()), if(!ftp_mdtm())

but has some effects on true that can cause additional coding. Sorry if this is the wrong place for it (please let me know where to send these so that I dont repeat this mistake)

Thanks.

These can easily be emulated in userspace as is.

function ftp_file_exists($ftp, $file) {
    $tmp = ftp_nlist($ftp, $file);
    return is_array($tmp) ? true : false;
}
function ftp_is_dir($ftp, $dir) {
    return @ftp_chdir($ftp, $dir. "/..");
}
function ftp_is_file($ftp, $file) {
    $tmp = ftp_nlist($ftp, $file);
    return is_array($tmp) && count($tmp) == 1 ? true : false;
}

If this were to be implemented at extension level the code would probably do the exact same thing.

Can't see any reason to implement it.

The suggested method to emulate ftp_is_file() does not work correctly!
Imagine you check a path linking to an directory with only one file in it then the function would return true although the path belongs to an directory.
