i am writting this code under Linux but nothing is appearing while the same code is given the output on the local server.
the php version on redhat linux 7.2 is PHP 4 so what should i do that the HTTP header variables will be shown.

Which version of PHP you are using on linux, 4.0.5, 4.2 or 4.4?

Take a look at $_SERVER.
