How to detect local host?

Hello,

in order to use my scripts developed at home directly after upload, I
wish to define a variable $root at begin of each script in a way that
it always - be it here at home or on any other computer - contains the
correct path to the web docs directory. How shall I do that the best
way? (At least, how do I get the local IP or hostname? Or is there an
environment variable?) Grepped 4 thick books but nothing found...

TIA, Daniel

$_SERVER['DOCUMENT_ROOT'] but maybe that's Apache specific, dunno.

If I understand you right, .... what I do is look at the SERVER variable
HTTP_HOST.

if ($_SERVER['HTTP_HOST'] == 'localhost')
{
// the script is running on my home computer and not on the remote server
}
else
{
// $_SERVER['HTTP_HOST'] contains the domain name where my script is running
}

Integrity is obvious.
The lack of it is common.

$_SERVER['SERVER_NAME'] will return the name of the server. This will be
either 'LOCALHOST' or something different.

You should not need this anyway as $_SERVER['DOCUMENT_ROOT'] will contain
the right information. This works for me as I develop on Windows and upload
the same scripts to a Linux box.

i use a config file for these cases, because usually not only pathes
differ between your dev box at home and the actually server (database
pswd do often, for instance).
i require that file at the top of each script and keep two different
config files.

I use php in web and batch mode, and some of the $_SERVER variables
don’t work in batch mode. I use getcwd
http://ca3.php.net/manual/en/function.getcwd.php to look at the path,
and from that detect where the app is running.
