如何在PHP中设置自定义标头 [英] How to set custom headers in PHP

问题描述

JAVA开发人员在标头中发送数据。我这样说吧

JAVA developer send me data in headers. I take it this way

$_SESSION["HTTP_COUNTRYNAME"];

如何使用标题回复？它试过 header（countryname：USA）; 但是php function headers_list 没有显示它。

How to make response back with headers? It tried header("countryname: USA"); but php function headers_list doesn't show it.

推荐答案

header('countryname: USA');
print_r(headers_list());

Array ( [0] => X-Powered-By: PHP/5.3.0 [1] => countryname: USA ) 

...对我有用。

你确定之前没有输出任何东西吗？开始打印文本后，无法设置标题。使用 headers_sent（）查看标题是否已发送（即，如果您已输出内容）。

Are you sure you haven't output anything before it? You cannot set headers after you've started printing text. Use headers_sent() to see if the headers have already been sent (that is, if you've already output something).
