Question

我想要做的是，更改以下变量将给出的值。例如我有汽车1并且它的前三个属性将被修复，例如汽车的种类，颜色及其ID /名称但我想要做的是给出一个其他值的列表，每当页面刷新时，盔甲，轮子，引擎和门都可以随机更改。我会把我的代码放在下面谢谢，如果我不清楚，对不起，我将列出每个随机值可以是什么，所以请任何帮助将不胜感激！谢谢！

    public $armour;
    public $wheels;
    public $engine;
    public $doors;


    public function __construct($id, $colour, $type, $armour, $wheels, $engine, $doors)

看起来你需要这个，而不是你所描述的：

$my_array = array("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "0", "1", "2", "3", "4", "5");
$car1->armour = array_rand($my_array);
