fopen opens a file, and gives you a file handle that you can then use with
other functions that may read or write from or to that file. It won't output
anything on its own.
See for example http://uk2.php.net/manual/en/function.fread.php
If you just want to output the contents of a file, then there's:
http://uk2.php.net/manual/en/function.readfile.php
... and then the rest of the functions in that section of the manual.
