Php 为什么在课堂上重复内容？

我编写了一些类来准备信息，并将其发送给父类以获取teplate：

说明：

创建对象：

查看socialfeed/模板：

---

这不难解释，因为这里有连接$this->template.=$video->getTemplate；看到了吗？=？是的，它是正确的。所有结果都是一个字符串。我尝试了var_dump$this->data，看到$media exix只在一个数组中，这是一个很好的方法，但不理解为什么它会显示在任何模板中，那么您希望看到什么呢？如果你的$this->模板已经有一些字符串，并且你用另一个字符串连接了它-其中有两个字符串。是的，例如有两篇文章，第一个视频和文章。视频的获取字符串模板和文章中的获取字符串。在将它们组合为commnon字符串之后，在一个字符串中获得两个post。但是我找不到一个错误，为什么从一个对象到另一个对象的数据是循环中的开关？
