标头(“位置")会导致[500]内部服务器错误? [英] header("location") causes [500] internal server error?

问题描述

我不知道是什么原因导致此错误.我的Apache日志未在有关该页面的访问日志或错误日志中记录任何错误，但是无论如何，无论何时取消注释header()行，都会收到500 Internal Server Error.在调用header()之前输出内容时，它不可能来自PHP的致命错误，那不会导致500吗?

I cannot figure out what could be causing this error. My Apache log is not recording any errors in the access log or error log regarding the page, yet somehow whenever I uncomment the header() line I get a 500 Internal Server Error. It can't be coming from PHP's fatal error when content is outputted before header() is called, that wouldn't cause a 500 would it?

header("Location: /offices/page-".ceil($cache->size() / 15));

我测试了$cache->size()，它返回22，因此应在字符串末尾附加2并重定向.我确实在header()之前调用过ob_start()，但是我尝试在它之前调用ob_end_clean()，但它仍然无济于事...

I tested $cache->size() and it's returning 22, so it should append a 2 to the end of the string and redirect. I did have ob_start() called before the header() but I tried calling ob_end_clean() right before it and it still did nothing...

我什至尝试将header("Location: /offices");放在文件的开头，但仍然可以得到500.

I even tried putting header("Location: /offices"); at the very beginning of the file and it still gives me a 500.

推荐答案

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?
