如何使用许多＆＃34;或＆＃34;来优化if请求？运营商？

Question

如果我有很多＆＃34; ands＆＃34;有没有办法减少代码？和＆＃34; ands＆＃34;在我的if请求相同的值？我只需要$row['animal']一次：

  if ($row['animal'] == "cat") or 
     ($row['animal'] == "dog") or 
     ($row['animal'] == "bird") or 
     ($row['animal'] == "monkey") or 
     ($row['animal'] == "mouse") or 
     ($row['animal'] == "hedgehog"){
     echo "many animals";}

Answer 1

echo in_array($row['animal'], array('cat', 'dog', 'bird', 'monkey', 'mouse','hedgehog'))
      ? 'many animals' 
      : 'no animals';
