environmental variables

[Anon]

Is there a site or a webpage that has a list of environmental variables?

Or I just need the variable that outputs the entire URL.

Thanks

Check out :

http://www.php.net/manual/en/language.variables.predefined.php

Information and links are within that page too. To view the ones available on your server, run phpinfo() :

<?php

phpinfo()

?>

It will provide some very useful information.

note: HTTP_HOST may not always be set.

echo $HTTP_HOST,$SCRIPT_NAME;
