How to set custom headers in PHP
提问by Dimash
JAVA developer send me data in headers. I take it this way
JAVA 开发人员在标题中向我发送数据。我这样理解
$_SESSION["HTTP_COUNTRYNAME"];
How to make response back with headers? It tried header("countryname: USA");but php function headers_listdoesn't show it.
如何使用标头回复回复？它试过了，header("countryname: USA");但 phpfunction headers_list没有显示出来。
回答by Andreas
header('countryname: USA');
print_r(headers_list());
Array ( [0] => X-Powered-By: PHP/5.3.0 [1] => countryname: USA )
...works for me.
...对我有用。
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).
你确定你之前没有输出任何东西吗？开始打印文本后，您无法设置标题。使用headers_sent()，看是否标头已经发送（也就是说，如果你已经输出的东西）。
