php - Where Operator In Laravel -

i need use operator check ids in table following

 $subscids  = subjectschedule::where('subject_start_id',input::get('substid'))                         ->wherenull('deleted_at')                         ->select('id')->get();   $subscidsarray = array() ;   foreach ($subscids $id)   {    $subscidsarray [] = $id->id ;  }  // here issue  $subscinstudattends = studentattendees::wherein('subject_schedule_id',$subscidsarray)                                        ->select('subject_schedule_id')->get();     if ($subscinstudattends)    {          return " true " . $subscinstudattends;   }else{          return "false";     } 

my issue in code

 $subscinstudattends =  studentattendees::wherein('subject_schedule_id',$subscidsarray)                                          ->select('subject_schedule_id')->get();   

wherein working fetch id in $subscidsarray, need check each id of ids if one id in $subscidsarray not equal subject_schedule_id' return false ;

how can ? suggestions ?

you can check length of array contains ids against length of records returned.

if( count($subscidsarray) == count($subscinstudattends) ){     // ids in array have corresponding record in database } 

or better, if application logic permits it, count of records , compare length of ids array.

$subscinstudattendscount = studentattendees::wherein('subject_schedule_id', $subscidsarray)->count('subject_schedule_id');  if( count($subscidsarray) == $subscinstudattendscount ){     // ids in array have corresponding record in database } 

this code assumes ids in database unique.
