Output of the code is output image

When I display or store related activity or timeperiod then timeperiods which I select repeated for all selected activity

My code for store or display data is

<?php
if(isset($_POST['submit']))
{
    foreach($_POST['arr'] as $input)
    {
        $ser = $input['service'];
        foreach($input['activity'] as $act)
        {

            $query = "insert into serviceactmap(service,activity)values('$ser','$act')";
            $conn->query($query);
            foreach($input['timeperiod'] as $time)
            {

               $sql = "insert into acttimemap(activity,timepriod)values('$act','$time')";
               $conn->query($sql);
            }


        }



    }
}
?>

In my code when I select any service and activity then service and activity store properly but when I select any timeperiod related to any activity then all selected activity repeated for all activity

for example

  1. When I select any TDS ->25form->monthly,qurterly
  2. And TDS->31Lower Deduction application->monthly,yearly

Then My output is

  • TDS->25form->Monthly,qurterly,monthly,yearly
  • TDS->Lower Deduction application->Monthly,qurterly,monthly,yearly

My expected output is

  • Tds->25form->monthly->25form->qurterly
  • Tds->Lower Deduction application->monthly->Lower Deduction application->yearly
