我目前的PHP类变量设置如下:

class someThing {

    private $cat;
    private $dog;
    private $mouse;
    private $hamster;
    private $zebra;
    private $lion;

    //getters, setters and other methods
}

但我也看到人们使用单个数组来存储所有变量:

class someThing {

    private $data = array();

    //getters, setters and other methods
}

你用哪个,为什么？各有哪些优缺点？
