Комментарий: The important thing to note here is that the $myarray array’s key value is being referenced without quotes around it. Because of this, the key being accessed is not the myvalue string but the value represented by the myvalue constant. Hence, it is equivalent to accessing $myarray[10], which is Dog, and Answer A is correct.
