header sent come in php when output already sent by php any how before header redirection happen or header sending process start by header function
so you need to remove function which already sending output before header function run.
so go to func.php at line 46 check whether any code is sending output like echo or print any of it
if yes you need to remove it or store it buffer until all program run and view start .
