PHP脚本安装进度步骤?
有些脚本没有 JavaScript 来刷新页面本身,但当它们执行逐步安装时,它们可以自动将新文本/步骤/说明推送到网页。
他们是如何做到这一点的?
Some scripts don't have javascript to refresh the page itself but when they are performing step by step installation, they can auto push new texts / steps / instructions to the web page.
How do they do this?

从你的问题中我并不完全清楚你的意思(或相当广泛),这取决于这是如何完成的,所以一个具体的例子会很有用。
无论如何,通常这是通过创建安装程序会话然后将表单提交到控制器来完成的,该控制器将处理输入并决定输入和当前会话的状态接下来显示什么。
It's not entirely clear to me from your question what you mean (or pretty broad), this depends on how this was done, so a concrete example would be useful.
Anyway, normally this is done by creating an installer session and then submitting forms to a controller which will handle the input and decide upon the input and the current session's state what to display next.
