here is my code

 public function taskTypes()
    {

        ini_set('max_execution_time', 5000);
        ini_set('memory_limit', '5000M');

        $this->middleware('auth');
        if (!Auth::user()->can('tasks_types'))
            abort(403);
        $page_title = 'Tasks';

        $userID = Auth::user()->id;
        //echo $userID;die;

        $projects = ['' => 'Select Project'] + Projects::lists('project_name', 'id')->all();
        $sections = ['' => 'Select Section'] + Department::lists('department_code', 'id')->all();
        $task_status = ['' => 'Select Task Status','Ongoing' => 'Ongoing','Completed' => 'Completed','Overdue' => 'Overdue'];
        $users = User::lists('emp_name', 'id')->all();

        if((Auth::user()->hasRole('superadmin')) || (Auth::user()->hasRole('manager'))|| (Auth::user()->hasRole('administrator ')))
            $ongoingTaskData = Task::where('status', '=', 'Ongoing')
                ->orderBy('id', 'DESC')
                ->get();

        else {
            $ongoingTaskData = Task::whereHas('users', function ($query) {
                $query->where('task_user.user_id', '=', Auth::user()->id);
            })
                ->where('status', '=', 'Ongoing')
                ->orderBy('id', 'DESC')
            ->get();
        }


        if((Auth::user()->hasRole('superadmin')) || (Auth::user()->hasRole('manager'))|| (Auth::user()->hasRole('administrator ')))
            $pendTaskData = Task::where('status', '=', 'Overdue')
                ->orderBy('id', 'DESC')
                ->get();

        else {
            $pendTaskData = Task::whereHas('users', function ($query) {
                $query->where('task_user.user_id', '=', Auth::user()->id);
            })
                ->where('status', '=', 'Overdue')
                ->orderBy('id', 'DESC')
                ->get();
        }

        if((Auth::user()->hasRole('superadmin')) || (Auth::user()->hasRole('manager'))|| (Auth::user()->hasRole('administrator '))) {
            $completedTaskData = Task::where('status', '=', 'Completed')
                ->orderBy('id', 'DESC')
                ->get();
            //set for view
            $enable = 'display:block';
            $colNum = '3';
        }

        else {
            $completedTaskData = Task::whereHas('users', function ($query) {
                $query->where('task_user.user_id', '=', Auth::user()->id);
            })
                ->where('status', '=', 'Completed')
                ->orderBy('id', 'DESC')
                ->get();
                //set for view
                $enable = 'display:none';
                $colNum = '4';
        }


        //echo "<pre>";print_r($ongoingTaskData);die;


        return view('tasks.tasks_info', compact('page_title','sections','task_status','enable','colNum','projects', 'users', 'ongoingTaskData', 'pendTaskData', 'completedTaskData'));
    }

for each ongoing task check if expiration date is greater than Carbon::now() carbon has a function for this i believe
