> > > Warning: Cannot add header information - headers already sent by > > (output > > > started at /users/ppowell/web/my/process.php:5) in > > > /users/ppowell/web/my/process.php on line 76 Ok, that tells you that the "output started at ... /process.php:5", that means line 5, which is phpinfo(), which causes output to the browser...
