               from activity 
               join serviceactivitymap on activity.activity_id = serviceactivitymap.activity_id 
               where serviceactivitymap.service_id = 1";

$activityvalue = $conn->query($activityid) or die ($conn>error.__LINE__);
$activities = [];

while ($row = $activityvalue->fetch_assoc()) {
    $activities[] = $row;
}

$serviceid = "select * from service";
$servicevalue = $conn->query($serviceid) or die ($conn->error.__LINE__);
$services = [];

while ($row = $servicevalue->fetch_assoc()) {
    $services[] = $row;
}
foreach ($services as $service):

 <form action = "index.php   method = "post">
     <input name='serviceone[]' data-toggle="modal" data-target="#myModal" type='checkbox' data-id='Incometax' value="<?php echo $service['service_id']?>"/><?php echo $service['service_name']?>
     <br>

                    from activity 
                        join serviceactivitymap  on activity.activity_id = serviceactivitymap.activity_id

     $activities = [];

    while ($row = $activityvalue->fetch_assoc()) {

    }

    $serviceid = "select * from service";

    $servicevalue = $conn->query($serviceid) or die ($conn->error.__LINE__);

    $services = [];

    while ($row = $servicevalue->fetch_assoc()) {
        $services[] = $row;
    }
    foreach ($services as $service):

   <form action = "index.php"   method = "post">

   <input name='serviceone[]' data-toggle="modal" data-target="#myModal" type='checkbox' data-id='Incometax' value="<?php echo $service['service_id']?>"/><?php echo $service['service_name']?>

<?php foreach ($activities as $activity):?>
