i have two arrays which in which i am using foreach for them to display the result, here what i want is to check if id in the 1st array is present in the second, if not present then display them, i did the following code:

    foreach($name as $n){

            foreach($response as $r){

            if ($n->id != $r->cid) {
      
      
      echo $n->id;
      
      }
      }
      }

here the issue is if only one values is equal then its coming fine, but if 2 values are equal then all the results are displayed 2 times, like that if 3 then the results are displayed times and so on. can anyone please tell me how to fix this, thanks in advance

You can try it :

$tmpIds = [];
foreach($name as $n){
    foreach($response as $r){
        if ($n->id != $r->cid) {
            if(!in_array($n->id, $tmpIds)){
                $tmpIds[] = $n->id;
                echo $n->id;
            }
        }
    }
}
