西里尔文文本的 $_GET 编码问题
我正在尝试这段代码（在我的本地网络服务器上），
<?php
echo 'the word is / думата е '.$_GET['word'];
?>
但是当输入 ?word=проба 时，我得到了损坏的结果
the word is / думата е ����
该文档保存为“UTF-8 without BOM”，标题也是 UTF-8 。 我尝试过 urlencode() 和 urldecode() 但效果是一样的。 将其上传到网络服务器时，工作正常...
I'm trying this code (on my local web server)
<?php
echo 'the word is / думата е '.$_GET['word'];
?>
but I get corrupted result when enter ?word=проба
the word is / думата е ����
The document is saved as 'UTF-8 without BOM' and headers are also UTF-8.
I have tried urlencode() and urldecode() but the effect was same.
When upload it on web server, works fine...

如果您尝试发送 HTTP
Content-type标头来指示浏览器您的页面正在生成哪种编码/字符集，该怎么办？例如，类似这样的东西可能会有所帮助：
当然，这是如果您正在生成 HTML - 您可能是这样。
考虑到服务器级别有一个配置设置定义了默认发送哪种编码，也许您服务器上的默认编码是可以的，而本地服务器上的默认编码则不行。
自己发送这样的标头可以解决问题：它将确保编码始终设置正确。
What if you try sending a HTTP
Content-typeheader, to indicate the browser which encoding / charset your page is generating ?For instance, something like this might help :
Of course, this is if you are generating HTML -- you probably are.
Considering there is a configuration setting at the server's level that defines which encoding is sent by default, maybe the default encoding on your server is OK -- while the one on your local server is not.
Sending such a header by yourself would solve the problem : it would make sure the encoding is always set properly.
我想您正在使用 Apache Web 服务器。
Apache 配置有一个常见问题 - 配置中带有“AddDefaultCharset”的行应该被注释掉（在行的开头添加 #，或用“AddDefaultCharset off”替换该行），因为它“覆盖了中给出的任何编码”元 http-equiv 或 xml 编码标记中的文件”。
在我当前的安装（Apache2 @ Ubuntu Linux）中，该行位于“/etc/apache2/conf.d/charset”中，但在其他（Linux/Unix）设置中可以位于“/etc/apache2/httpd.conf”中，或“/etc/apache/httpd.conf”（如果您使用的是 Apache 1）。如果在这些文件中找不到它，可以使用“cd /etc/apache2 ; grep -r AddDefaultCharset *”（适用于 Apache 2 @ Unix/Linux）进行搜索。
I suppose you are using the Apache web server.
There is a common problem with Apache configuration - a line with "AddDefaultCharset" in the config should be commented out (add # in the begining of the line, or replace the line with "AddDefaultCharset off") because it "overrides any encoding given in the files in meta http-equiv or xml encoding tags".
In my current installation (Apache2 @ Ubuntu Linux) the line is found in "/etc/apache2/conf.d/charset" but in other (Linux/Unix) setups can be in "/etc/apache2/httpd.conf", or "/etc/apache/httpd.conf" (if you are using Apache 1). If you don't find it in these files you can search for it with "cd /etc/apache2 ; grep -r AddDefaultCharset *" (for Apache 2 @ Unix/Linux).
查看更改服务器编码。非常好的读物！
干杯!
Take a look at Changing the server encoding. An excellent read!
Cheers!
如果您从 AJAX 收到 $_GET，请确保您的 blablabla.js 文件采用 UTF-8 编码。您还可以使用 iconv("cp1251","utf8",$_GET['word']); 以 UTF-8 显示 $_GET['word']
If You recieve $_GET from AJAX make sure that Your blablabla.js file in UTF-8 encode. Also You can use
iconv("cp1251","utf8",$_GET['word']);to display your $_GET['word'] in UTF-8我刚刚遇到了这个问题，如果您使用 htmlentities() 过滤 GET 变量，有时会发生这种情况。看起来这个函数将西里尔字符转换成奇怪的东西。
I just had the issue and it sometimes happens if you filter the GET variable with htmlentities(). It seems like this function converts cyrillic characters into weird stuff.
