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, "~"); ?>
