php - How to use the array intersect method to match two values within 2 sets of arrays -

i have query:

$subcommon= mymodel::selectraw('subjectlist_id, count(subjectlist_id) aggregate')  ->wherein('user_id', [auth::id(), $user->id]) ->groupby('subjectlist_id')   ->having('aggregate','>',1) ->get(); 

which gives query result:

{"subjectlist_id":1,"aggregate":2} {"subjectlist_id":3,"aggregate":2} 

i have query:

$values = mysecondmodel::where('user_id', auth::id())                          ->first();  

which gives result:

{"id":1,"subjectlist_id":1, "article_id":4} 

because im finding way difficult join these 2 models i've decided output them arrays @ least 1 matching value subjectlist_id condition execute query i've displayed @ bottom. i'm assuming it's arrayintersect method im unsure how use it.

$values = mysecondmodel::where('user_id', auth::id())                            ->first();  

i have far:

 $subcommonarray = (array) $subcommon;  $valuesarray = (array) $values;  $a = $subcommonarray; $b = $valuesarray; $c = array_intersect_key($a, $b);  if (count($c) > 0) {      $newquery = mysecondmodel::where(user_id, auth::id())  ->first();   } 

but think comparing keys , not values. how match values , and key together?

well if $values , $subcommon both valid arrays, compare them using array_intersect function that:

$subjectlist_id = array_intersect($values, $subcommon); 

this go , search similarities in values, , construct array in $subjectlist_id variable of matching values between both arrays.

a example php documentation:

$array1 = array(2, 4, 6, 8, 10, 12); $array2 = array(1, 2, 3, 4, 5, 6);  $array3 = array_intersect($array1, $array2); var_dump($array3); 

this have such array:

array(3) {   [0]=> int(2)   [1]=> int(4)   [2]=> int(6) }
