I'm studying how objects and arrays work in PHP for a little project. Unfortunately it's difficult to find out what are good ways to deal with data, there are many solutions but i can't find the right solution for my problem. I think I prefer two work with an object.
I have two questions related to this example:
class cars {}
$cars = new cars();
$cars->brand = new cars();
$cars->brand->audi = "A6";
$cars->brand->opel = "insignia";
question 1 How can I get each brand as output for example with a for each loop or other function?
echo somesolution will give audi
question 2 Is there a way like with arrays using parentheses to write the code without repeating $cars->brand->opel ?
question 3 Why do I need tho create the class cars?
我正在研究对象和数组如何在PHP中为一个小项目工作。 不幸的是，很难找到处理数据的好方法，有很多解决方案，但我找不到适合我的问题的解决方案。 我想我更喜欢用对象做两件事。
我有两个与这个例子有关的问题：
class cars {}
$ cars = new cars（）;
$ cars-＆gt; brand = new cars（）;
$ cars-＆gt; brand-＆gt; audi =“A6”;
$ cars-＆gt; brand-＆gt; opel =“insignia”;
问题1 如何以每个循环或其他功能为例，如何将每个品牌作为输出？ \ n
echo somesolution将给出audi
问题2 是否有类似于使用括号的数组编写代码而不重复 $ cars-＆gt; brand-＆gt; opel ？
问题3 为什么我需要创建班车？
