调用header()后，脚本继续执行.您需要在其后立即放置exit;.不过，这不应引起500错误.

The script continues to execute after your header() call. You need put exit; immediately after it. This shouldn't cause a 500 error, though.

显然这可行-这意味着您的问题可能出在页面下方的一些相关代码中?

Evidently this worked - meaning your problem is probably in some related code further down the page?
