I wrote this program and it gives me as it is

<?php
phpinfo();
?>

the out come is still the same as

<?php
phpinfo();
?>

As you mentioned, this is a PHP problem, and doesn't belong in the MySQL forum.

The problem is that you haven't configured your web server to recognize your file as a PHP script. Your webserver needs to know what files should be sent through the PHP interpreter instead of being sent as plain text output.

Installation instructions for most servers are available at the language homepage:
  http://www.php.net/install
