PHP uses one of two methods to keep track of sessions. If cookies are enabled, like in your case, it uses them.
PHP 使用两种方法之一来跟踪会话。如果启用了 cookie，就像你的情况一样，它会使用它们。
If cookies are disabled, it uses the URL. Although this canbe done securely, it's harder and it often, well, isn't.See, e.g., session fixation.
如果 cookie 被禁用，它会使用 URL。虽然这可以安全地完成，但它更难，而且通常不是。参见，例如，会话固定。
Search for it, you will get lots of SEO advice. The conventional wisdom is that you should use the cookies, but php will keep track of the session either way.
搜索它，你会得到很多 SEO 建议。传统观点是您应该使用 cookie，但 php 会以任何一种方式跟踪会话。

It's the identifier for your current session in PHP. If you delete it, you won't be able to access/make use of session variables. I'd suggest you keep it.
它是您在 PHP 中当前会话的标识符。如果删除它，您将无法访问/使用会话变量。我建议你保留它。
