数组参数--灵活的运用变量和数组之间的互相转化

创建对象或者是一个函数操作的时候，如果参数的数量超过4个以上，应该用一个数组或者对象来整合这些参数。例如，初始化对象参数的时候，可以用一个数组来处理，通过构造方法灵活地实现对象参数初始化

class Thing
{
    public $id; 
    public $name; 
    public $zone;
    public $publish_time
    public $smallimg_url;
    public $isRented;
    
    public function __construct(array $option)
    {
 $this->tid = isset($option["id"])?$option["id"]:null;
 $this->name = isset($option["name"])?$option["name"]:null;
 $this->zone = isset($option["zone"])?$option["zone"]:null;
 $this->publish_time = isset($option["publish_time"])?$option["publish_time"]:null;
 $this->smallimg_url = isset($option["smallimg_url"])?$option["smallimg_url"]:null;
 $this->isRented = isset($option["isRented"])?$option["isRented"]:null;
    }

}

$info = compact('id','name','zone','publish_time','smallimg_url','isRented');
$thing = new Thing($info);
