为什么在添加<?xml version ="1.0"时encoding ="utf-8"?网页无法托管吗? [英] Why when add <?xml version="1.0" encoding="utf-8"?> to web page don´t work on hosting?
问题描述
我正在hostgator.com上开发一个简单的网页. 我有标准标题，但是当我添加以下行时:
I am developing a simple webpage at hostgator.com. I have the standard headers, but when I add the following line:
<?xml version="1.0" encoding="utf-8"?>
该页面不起作用.我想为什么.
the page does not work. I would like why.
这是完整的标题:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1 /DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="es" xml:lang="es">
... rest of code ...
服务器向我返回空白页
问题已解决: PHP短标签已打开.
Issue solved: The PHP short tags was open.
推荐答案
我最好的猜测是:
- 该文档正在作为PHP处理
- 短标签已打开
…因此服务器正在尝试将XML声明作为PHP代码处理.通常，我希望收到一条错误消息，但是可能正在使用PHP设置来抑制向客户端的错误，从而避免泄漏数据，这些数据可能对尝试使用安全漏洞的人有用.
… so the server is trying to process the XML declaration as PHP code. Normally I'd expect an error message, but perhaps there is a PHP setting in play that suppresses errors to the client to avoid leaking data that could be potentially useful to someone trying a security exploit.
只需将其删除.
- 默认为UTF-8
- 版本1.0为默认
- 它在规范中是可选的
- 给出text/html内容类型，XML序言将触发IE6的怪癖模式
后者是不可取的.前者都意味着没有区别.
The latter is undesirable. The former all mean it makes no difference.
