如何从PHP告诉服务器charset是UTF-8 ?? [英] how to tell server from PHP that charset is UTF-8??

问题描述

如何让PHP告诉服务器当我将文本回显到

屏幕时，我需要将文本作为UTF-8发送？当PHP生成所有文本时，Apache如何知道

正确的编码？如果我建立一个内容管理系统（我有）并且我确保所有

输入编码为UTF-8，那么
$ b将如何$ b服务器知道MySql数据库中的文本是UTF-8吗？

我正在接受所有用户输入并在输入上使用此功能：

http://us4.php.net/ manual / en / function.utf8-encode.php


我这样做，所以我可以输出到XML而不会出现错误

你不应该发送纯文本。


但服务器如何知道如何提供这些页面？我如何从PHP中告知

？我意识到我可以发送一个http等效标签，但是这相当于很弱，对吧？


这够了吗？与Apache的任何冲突？


$ sent = headers_sent（）;

if（！$ sent）header（" Content-type：text / html; charset：UTF-8"）;

How do I get PHP to tell the server that when I echo text to the
screen, I need for the text to be sent as UTF-8? How does Apache know
the right encoding when all the text is being generated by PHP? If I
build a content management system (I have) and I make sure that all
input is encoded as UTF-8, how will the
server know that the text in the MySql database is UTF-8?

I''m taking all user input and using this function on the input:

http://us4.php.net/manual/en/function.utf8-encode.php

I''m doing this so I can output to XML without getting errors about
"You should not sent plain text".

But how will the server know how to serve these pages? How do I tell
it from PHP? I realize I can send a http equiv tag, but that''s rather
weak, right?

Is this enough? Any conflicts with Apache?

$sent = headers_sent();
if (!$sent) header("Content-type:text/html;charset:UTF-8");

推荐答案

sent = headers_sent（）;

if（！

sent = headers_sent();
if (!

已发送）标题（Content-type：text / html; charset：UTF-8）;

sent) header("Content-type:text/html;charset:UTF-8");

发送带有charset属性的内容类型标头。

当所有文本生成时，Apache如何知道正确的编码PHP？


它不是，也不需要 - 这些信息仅供最终用户使用。

如果我构建
一个内容管理系统（我有），我确保所有
输入编码为UTF-8，

我不知道你的意思。 XML内容不必是UTF-8编码，

只是正确转义并且编码设置正确。

但服务器如何知道如何提供这些页面？我如何用PHP告诉它？我意识到我可以发送一个http等效标签，但这相当弱，对吧？


是的。

这够了吗？与Apache的任何冲突？

Sent a content-type header with a charset attribute.
How does Apache know
the right encoding when all the text is being generated by PHP?
It doesn''t, nor does it need to - that information''s just for the end user.
If I
build a content management system (I have) and I make sure that all
input is encoded as UTF-8, how will the
server know that the text in the MySql database is UTF-8?

Don''t know what you mean here. XML content doesn''t have to be UTF-8 encoded,
just properly escaped and the encoding set correctly.
But how will the server know how to serve these pages? How do I tell
it from PHP? I realize I can send a http equiv tag, but that''s rather
weak, right?
Yep.
Is this enough? Any conflicts with Apache?
