如何计算数据库表中的行？

Question

I want to make a variable

{{ $countEvents }}

which can count the number of rows from table Events...Now I have 18 rows( https://imgur.com/a/zt35XwV ), I want to use this variable to my view. How can I be able to count the number of rows?

I've tried this

$events = Event::count();

but I got all data with all columns from my database, not the number of it!

Answer 1

Controller:

$countEvents = Event::count();

return view('view-name-here', compact('countEvents'));

this will allow you to use {{ $countEvents }} in your view

Answer 2

You can use DB query builder facade.

$data['countEvents'] = DB::table('events')->count();

Now in blade you can check integer value of $countEvents

Answer 3

count is a Collection method. The query builder returns an array. So in order to get the count, you would just count it like you normally would with an array:

$eventCount = count($events);

If you have a Event model, then you can use Eloquent to get a Collection and then use the Collection's count method. Example:

$eventlist = Event::all();
$eventCount = $eventlist->count();
