如果我不调用 session_start() 会发生什么? [英] What happens if I don't call session_start()?

问题描述

我正在尝试将我站点中的许多页面作为 HTML 缓存.因此，我将无法在这些页面上调用 session_start().如果您不在每个页面上都调用会话，会话是否有效?

I'm trying to make many of the pages in my site cache-able as HTML. As a result, I won't be able to call session_start() on those pages. Do sessions work if you don't call them on every single page?

推荐答案

如果你不调用 session_start() 那么你将没有 $_SESSION 可用.但是，如果页面是静态 html 文件，那么该页面不需要 $_SESSION，因此您不必担心.

If you don't call session_start() than you won't have $_SESSION available. But if the page is a static html file anyway than you won't need $_SESSION for that page so you don't have to worry about it.

您只在使用 $_SESSION
