absolute path how to determine

I've placed a file/script inside my "tmp" directory just beneath the /public_html/ directory like this: /home/myaccount/tmp/public_html/

How can I determine what the absolute path is ?
/usr/..../...../home/myaccount/tmp

Thanks in advance !

if you have shell access, log in and type:

pwd

if not, in PHP you could do something like:

echo realpath ('.');

you talking abotu the realpath function in PHP?

pathinfo function?
<?php

$path_parts = pathinfo("/www/htdocs/index.html");

echo $path_parts["dirname"] . "\n";
echo $path_parts["basename"] . "\n";
echo $path_parts["extension"] . "\n";
