PHPでDao.Dto.Beansを簡単に書いてみた

<?php

//Bean
class HumanBeans
{
    private $name;
    private $age;
   
    public function setName($name){
        $this->name = $name;
    }
   
    public function setAge($age){
        $this->age = $age;
    }
   
    public function getName(){
        return $this->name;
    }
   
    public function getAge(){
        return $this->age;
    }
}

//Dto
class HumDto
{
    private $dtolist;
    private $ageTotal;
    private $ageAverage;
    public function HumDto(){
    }
   
    //リストをsetしサイズを返す
    public function listSet($dtolist){
        $this->dtolist = $dtolist;
        return count($this->dtolist);
    }
   
    //Ageの合計
    public function ageTotal(){
        for($i = 0 ; $i < count($this->dtolist) ; $i++){
            $this->ageTotal += $this->dtolist[$i]->getAge();
        }
        return $this->ageTotal;
    }
   
    //Ageの平均を返す
    public function ageAverage(){
        $this->ageAverage = $this->ageTotal/count($this->dtolist);
        return $this->ageAverage;
    }

}

//Dao
class HumDao
{
 　//今回は$humをDBのデータと見立てて使います　
     public $hum = array(
         0 => array('name' => 'ito' , 'age' => 9,),
         1 => array('name' => 'suzuki' , 'age' => 21,),
        2 => array('name' => 'tanaka' , 'age' => 33,)
     );


    public function HumDao(){
        $humlist = array();
        //print_r ($this->hum);//配列データ
        $humdto = new HumDto();//Dto
        echo "<br>";
        for($i = 0 ;$i < count($this->hum) ; $i++){
            $bean = new HumanBeans();
            $bean->setName($this->hum[$i][name]);
            $bean->setAge($this->hum[$i][age]);
            $this->humlist[] = $bean ;
        }
       
        echo $humdto->listSet($this->humlist)."データサイズ<br>";//Dtosetデータサイズ
        echo $humdto->ageTotal()."Ageの合計<br>";//Ageの合計
        echo $humdto->ageAverage()."Ageの平均<br>";//Ageの平均
       
        //var_dump($this->humlist);
        for($i = 0 ; $i < count($this->humlist) ; $i++){
            echo "名前：".$this->humlist[$i]->getName()." ";
               echo "年齢：".$this->humlist[$i]->getAge()." ";
            echo "<br>";
        }
    }
}

new HumDao();
