为动物熊创建一个PHP类

我正在寻找一种名为“Bear”的单一类能够：

• 每两小时吃一次蜂蜜，记住他们上次吃蜂蜜的时间
• 决定他们是否需要睡觉

我想知道是否有一种方法可以做到这一点，而不必硬编码数组时间，也不必使用else语句来决定bear是否需要睡眠单独的函数会更好、更干净吗？

class Bear

{

protected $name;
protected $currentTime;


public function setName($name)
{
   $this->name = $name;
}

public function getName()
{
   return $this->name;
}

public function showLastFeedtime()
{
   $lastFed = strtotime('-2 hour', strtotime($this->currentTime));

   $newdate = date('H:i', $lastFed);

   echo $this->name." last ate at ".$newdate."<br/><br/>";   
}

public function checkFeedingTime($checkHours = array())
{
   if(in_array($this->currentTime,$checkHours))
{
echo "It's ".$this->name."'s feeding time </br>";
echo "The time ".$this->currentTime. " is the time and I'm eating 
honey at right now. </br></br>";

echo "These are the times I eat</br>";

foreach($checkHours as $feedingTimes)
{
   echo $feedingTimes."</br>";    
}

echo "<hr>";

}
else
{
  //DECIDE IF THE BEAR NEEDS TO SLEEP
  echo "Barney is having a snooze";
}

}

public function getTime($currentTime)
{
   $this->currentTime = $currentTime;
}

public function setTime()
{
   return $this->currentTime;
}

}

//new instance of barney
$barney = new Bear();

//set the bears name
$barney->setName('Barney');

//get the bears name
$bigBear = $barney->getName();

//page info
echo "<h1>".$bigBear."'s profile page </h1>";
echo "<hr>";
echo "I am a bear and my name is {$bigBear} <br/>";
echo "<hr>";

//the current time
$currentTime = date('H:i');

$barney->getTime($currentTime);

//last feeding time
$barney->showLastFeedtime();

//ARRAY TIMES-barney eats every 2 hours
$checkHours = 
array('00:00','02:00','04:00','06:00','08:00',
'10:00','12:00','14:00','16:00','18:00','20:00','22:00');

//call the feeding time function
$barney->checkFeedingTime($checkHours);
?>
