[RESOLVED] PHP Domain Check

[tomcatexodus]

If I configure a sub domain on a hosting server, and the domain/sub domain point at the same directory to filter through a common front-controller, would it be accurate to perform a check on $_SERVER['SERVER_NAME'] in said front-controller, to determine from where a user has accessed the site?

HTTP_HOST and SERVER_NAME would both work fine as long as you've got a properly configured web server. sometimes, SERVER_NAME could return something unexpected if your server name definitions aren't set explicitly, however.

Thanks kows, SERVER_NAME does the trick, I was just curious of it's consistency in accuracy.
