PHP：无法更改404状态码，但header（）中没有错误 [英] PHP: Can't change 404 status code, but there is no error from header()
问题描述
我在自定义的PHP网站上处理不可破坏的页面。为此，我使用这一行创建了一个.htaccess文件：
ErrorDocument 404 /index.php
code> 在index.php的开头，我放置了这段代码：
header（$ _ SERVER ['SERVER_PROTOCOL']。'200 OK'，true，200）;
这适用于我的WAMP环境。我正在检查http标题，并且它会抛出：
Status = OK - 200
但是在我的Linux主机中，我总是得到：
状态=未找到 - 404
奇怪的部分是PHP不会抛出任何错误总之......这就像是重写我的头文件。
我需要更改状态码头，否则IE7和IE8不会处理我的结果页面。其他浏览器可以解决这个问题。
也许我需要.htaccess或php.ini中的内容，但是没有找到任何相关的内容。或者，如果您知道任何其他方法来重定向404并返回200，请告诉我。
更好的重写方法不存在的页面到PHP文件是这样的：
RewriteEngine On
RewriteCond％{SCRIPT_FILENAME}！-d
RewriteCond％{SCRIPT_FILENAME}！-f
RewriteRule（。*）index.php
这使用mod_rewrite将任何不是目录而不是文件的内容更改为PHP脚本。只要记住，如果你的PHP脚本收到一个不存在的东西的请求，它应该发送一个404头。
I'm processing unavaliable pages in my custom PHP website. To do this I created a .htaccess file with this single line:
ErrorDocument 404 /index.php
At the beginning of index.php I placed this code:
header($_SERVER['SERVER_PROTOCOL'].' 200 OK', true, 200);
This works perfect in my WAMP environment. I'm checking http headers, and it throws:
Status=OK - 200
But in my Linux hosting I always get:
Status=Not Found - 404
And the weird part is that PHP isn't throwing any error at all... it's like something is overriding my headers.
I need to change the status code header, otherwise IE7 and IE8 won't process my result page. Other browsers can deal with this.
Maybe I need something in .htaccess or php.ini, but haven't found anything related. Or, if you know any other method to redirect a 404 and return 200, let me know.
A better method of rewriting non existent pages to a PHP file is this:
RewriteEngine On
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule (.*) index.php
This uses mod_rewrite to change anything that is not a directory and not a file to your PHP script. Just remember that if your PHP script recieves a request for something that isn't there, it should send a 404 header.
