Initialize $score before the loop and also print the output after loop.

$score = 0; 
foreach($request->jawaban as $key => $value){
    $soal = Soal::find($key);
    $kunci = $soal->kunci;    
    if($value === $kunci){
       $score+=1;
    }
}
echo $score;

You need to echo after loop. As below:

    $score = 0; //define this variable before loop
    foreach($request->jawaban as $key => $value){
        $soal = Soal::find($key);
        $kunci = $soal->kunci;    
        if($value === $kunci){
           $score+=1;
        }
    }
    echo $score; // echo after loop end

Hope it helps you.

Based on what others have said: But just to show you the full code

$score = 0; //define this before the loop

foreach($request->jawaban as $key => $value){
    $soal = Soal::find($key);
    $kunci = $soal->kunci;    

    if($value === $kunci) $score+=1; //simplify this, as I am lazy coder.
}

echo $score; //echo the final value, after the loop finishes.

Good Luck.
