Putting Evaluated Contents Of Include File Into Varialble

Hi, I have an file that contains PHP code..variables, db, etc. Is it possible to include the evaluted contents of that file into a variable in another, the calling PHP script? Essentailly I am looking to do something like include("myCode.php") -> HTML Output -> $myVariable. I know could do this with something like $myVariable=file_get_contents("http://localhost/myCode.php") but I am not allowed to use urls in file opens. Any suggestions? Thanks, Michael
