server folder?

[jackvull]

How do I get the server folder to be returned?
I access a site via http://example.com/FolderName/index.php

I want to header it back to http://example.com/FolderName/somethingelse.php

but because I have a development and live site, the folder names are different.
Anyway to pick up http://example.com/FolderName/

You could parse it out of $_SERVER variables, but it might be best to do a hard coded setting.

[jackvull]

hard coding in the dev environment means that everytime the page is released to live, the code also has to be changed.
PHP_SELF works but then I need to take off everything after the last forward slash /

?

Hard coding would not be an issue if you have the setup in an external file.

You would in theory never need to upload this setup again, so you can have one local and one live.

As for parsing the PHP_SELF, strrpos gets the last occurance of a needle within a string.

$url = substr ($_SERVER['PHP_SELF'], 0, strrpos ($_SERVER['PHP_SELF'], "/") + 1);

i'll sometimes define these kind of variables in db.php along with default variables.

i.e. paths to command line tools, different database names, server ip addresses (for when running cron jobs that need to know them) etc.
