including files...

hi was just wondering if there was a way to have a php file with all constant variables like db mysqluser and password and a few other things defined in a file of its own and then be able to use the variables in it for the project it was built for? the last i knew it could be done and all i needed to do was make the file put the definitions in it and then put: include("filename.inc"); at the top of the page..is this right or is there more to it than that? --- Outgoing mail is certified Virus Free.
