PHP is great. I just found a function which display the Arbsolute of a file. This function is helpful when you are writing scripts or code in you PHP so that you know what exactly your root absolute relative path is:

getcwd()

-- Gets the current working directory

The only requirement for this to work on your web pages is that you have PHP in your hosting. IF you don't have php, you can signup with www.webune.com for a php plan. if you have php, continue on...

copy and paste this code into your text editor, you can use windows notepad if you like:

now save the file as : absolutepath.php and upload to your server with php hosting and it will display the directory of the absolute path of where the script is.

Remember, you will need php for this to work, if you dont have php yet, you can sign up at: www.webune.com

This is an example of the output:
The Absolute Path is: /var/www/html/public_files


I hope this helps.
