Laravel WhereNotIn只有一个数字

Question

Here is code:

$all = "32,34,24,28,31";
 $show_app = DB::table('apartments')
->whereNotIn('id', [$all])
->get();

I don't know why variable $all not working. When is listed only hide first apartment "32". Rest apartment list anyway. But if i copy all numbers in whereNotIn then is working??? I need this variable @all! I have all variable in my table. I try with ->toSql() and show only one "?" instead of five "?, ?, ?, ?, ?"

Answer 1

I am not a laravel user, but in your all variable, why not directly assign the array instead of saving as string?

Example: Instead of:

$all = "32,34,24,28,31";

why not?

$all = [32,34,24,28,31]; 

Then use the $all variable like this:.

 $show_app =    DB::table('apartments') ->whereNotIn('id', $all) ->get();

Answer 2

i found my problem: I must use explode

$result="";
foreach($prikaz_bookinga as $prikaz_booking) :  
$result.=$prikaz_booking->id.','; 
endforeach ;
$all=rtrim($result, ',');

Then in query add this.

 ->whereNotIn('id', explode(',', $all))
