How can I Update this $s var in PHP (LARAVEL)?

Question

I'm using : PHP 8.0.9 (cli) (built: Jul 29 2021 14:12:19) and LARAVEL 8.

I don't know for some reason after pushing element to $s, the $s (outside loop) wont update it's value to ["...",".","ok"]. I'm using Illuminate\Support\Arr::exists() to check if the value already added to $s. I keep getting ["...",".","ok","ok","ok"]. What i want is ["...",".","ok"]. Is anyone know what im doing is wrong? Thanks.

public function showImportForm(){ // ignore this
        if ($_SESSION['current'] == session_id()) { // ignore this
            $s = array("...", ".");
            for ($i=1; $i<=3; $i++){
                if(!Arr::exists($s, "ok")){
                    $s[] = "ok";
                }else{
                    print("skip");
                }
            }
            return $s;
            //return view('database.import');
        }
    }

Just have a look at the definition of Arr::exists:

Determine if the given key exists in the provided array.

That method does not check whether the value is already present in the array. Use in_array instead
