SORRY, here is the correct array ... that's not the problem.
$final[0]['name'] = "fire";
$final[0]['value'] = 0;
$final[0]['id'] = 1;
$final[1]['name'] = "air";
$final[1]['value'] = 0;
$final[1]['id'] = 2;
$final[2]['name'] = "infinity";
$final[2]['value'] = 0;
$final[2]['id'] = 3;
$final[3]['name'] = "water";
$final[3]['value'] = 0;
$final[3]['id'] = 4;
$final[4]['name'] = "earth";
$final[4]['value'] = 0;
$final[4]['id'] = 5;
