Write the following statement in a method in a controller

public function test()

{

echo 'dirname(__FILE__) ' . dirname(__FILE__) . '
';

echo 'dirname(__ROOT__) ' . dirname(__ROOT__) . '
';

echo '__ROOT__ ' . __ROOT__ . '
';

//echo '__Public__ ' . __Public__ . '
';

echo '';

echo '__FILE__ ' . __FILE__ . '
';

echo '$_SERVER["PHP_SELF"]' . $_SERVER['PHP_SELF'] . '
';

echo '$_SERVER["SCRIPT_NAME"]' . $_SERVER['SCRIPT_NAME'] . '
';

echo '$_SERVER["SERVER_HOST"]' . $_SERVER['SERVER_HOST'] . '
';

echo '$_SERVER["SERVER_NAME"]' . $_SERVER['SERVER_NAME'] . '
';

echo '$_SERVER["SERVER_PROTOCOL"]' . $_SERVER['SERVER_PROTOCOL'] . '
';

echo '$_SERVER["SERVER_FILENAME"]' . $_SERVER['SCRIPT_FILENAME'] . '
';

echo dirname($_SERVER['SCRIPT_FILENAME']);

echo __DIR__;

}
