Answer 1

As far as I understand. You might have is_present will be an array format from view like name="is_present[]". If this your case then the below code will work fine. if not then you can't use count() if input is not an object or array
public function mark_attendence(Request $request)
{
for($i = 0; $i < sizeof($request->is_present); $i++)
{
$emp = new employee_attendence();
if($request->is_present[$i] == "Present")
$emp->is_present = "Present";
if($request->is_present[$i] == "Absent")
$emp->is_present = "Absent";
$emp->date = now();
$emp->user_id = $request->user_id[$i];
$emp->save();
}
return redirect('/index')->with('succ','Attendence Added Successfully');
}

In your Add Attendance method try this
this worked for me
for($i = 0; $i < sizeof($request->is_present); $i++)
{
$emp = new employee_attendence();
if($request->is_present[$i] == "Present")
$emp->is_present = "Present";
if($request->is_present[$i] == "Absent")
$emp->is_present = "Absent";
$emp->date = $request->date;
$emp->user_id = $request->user_id[$i];
$emp->save();
}
