title: Laravel Eloquent mutiple counts with different conditions in one query
body: <p>I have code like below:</p>
  
  <pre><code>$sendto_hikkou1 = Guest::where('mypage_id', $mypage)
                  -&gt;where('snd_to_hikkou_id', 1)-&gt;count();
  $sendto_hikkou2 = Guest::where('mypage_id', $mypage)
                  -&gt;where('snd_to_hikkou_id', 2)-&gt;count();
  $sendto_hikkou3 = Guest::where('mypage_id', $mypage)
                  -&gt;where('snd_to_hikkou_id', 3)-&gt;count();
  </code></pre>
  
  <p>How can I write this in one query? </p>
