Answer 1

$allcount = 0;
$query1 = User::where('sponser_id',$_SESSION['ruserid'])->get('userid');
$count1 = count($query1);
$allcount = $allcount + $count1;
for ($i=2; $i<8; $i++) {
if ($i>2){
$j = $i-1;
${"query".$j} = User::whereIn('sponser_id',${"query".($j-1)})->get('userid');
}
${"query".$i} = User::whereIn('sponser_id',${"query".($i-1)})->get('userid');
${"count".$i} = count(${"query".$i});
$allcount = $allcount + ${"count".$i};
}
return $allcount;
