Scheduled post published event future_to_publish

I am trying to refresh the front page after a scheduled post published.

add_action('future_to_publish', 'do_stuff', 10, 1);
function do_stuff( $in ) {
//part 1
$f = fopen( dirname(__FILE__).'log1.log', 'a' );
  fwrite( $f, "\nBefore\n" );
  fwrite( $f, print_r($in, true) );
  fwrite( $f, "\nAfter\n" );
  fclose( $f );
//part 1 ends
//part 2
redirect('index.php');
//part 2 ends
}

function redirect($loc){
	echo "<script>window.location='".$loc."'</script>";
}

The part 1 works perfectly but part 2 don’t.

Any help Please…
