ftp_cdup can only up to the parent and if you want test a directory that is not a child then you can't with ftp_cdup ;)

The below example doesn't seem to work on a windows based machine so I use this trick instead

<?php

$aPath
= explode('/',ftp_pwd($conn_id));
$sHomeDir = str_repeat('../', count($aPath) - 1);

ftp_chdir($conn_id, $sHomeDir);

?>

I used a recursive cdup function until i realised i could navigate to the user's home directory from any location using ~:

<? ftp_chdir($connid, "~"); ?>

i think ftp_cdup can make it more nice

function dirExists($ftp, $directory = '.') {
    if (@ftp_chdir($ftp, $directory)) {
        ftp_cdup($ftp);  
        return TRUE;
    } return FALSE;
}
