Hii Mrwinh,
Php is the server side scripting language. if you want to execute it fisrt of all you will have to install wamp or xammp after that put your code in wamp/www/flename.php and paste your code in filename.php. If it does not work then turn on your browser buffer using ob_start(); ie predefied function of php. second possiblity check your port number whether it has been assigned to other services or not.By deafult port no supported by apche is 80.
