How can I forbid access to an URL in PHP? -

if have url called: www.example.com , have application in next url: www.example.com/app/, how can forbid access www.example.com not app? simple way?

thanks.

if need within php, can set right http status , exit program:

if ($_server['path_info'] === '/') { header('', false, 403); die('access forbidden.'); }

see header() docs , description of http homecoming codes.

but in general case, @cooper , others right, server config improve location handle globally.
