Setting PHP default encoding to utf-8?
提问by JDelage
In the "PHP Cookbook", they say (p.589) that to properly set the char encoding of outgoing data to utf-8 it is necessary to edit the default_encodingconfiguration to utf-8.
在“PHP Cookbook”中，他们说 (p.589) 要将输出数据的字符编码正确设置为 utf-8，必须将default_encoding配置编辑为 utf-8。
However, I cannot find this configuration in php.ini. Should I simply add a line that would say default_encoding = "utf-8"?
但是，我在php.ini. 我应该简单地添加一行会说default_encoding = "utf-8"吗？
I do have a ;default_charset = "iso-8859-1". As you can see (;), right now it is not activated. Should I remove the semi-colon and set it to "utf-8"? Does that take care of the default encoding?
我有一个;default_charset = "iso-8859-1". 如您所见 ( ;)，现在它没有被激活。我应该删除分号并将其设置为"utf-8"吗？这会处理默认编码吗？
I also found other encoding directives that I don't know what to do about:
我还发现了其他我不知道该怎么做的编码指令：
[iconv]
;iconv.input_encoding = ISO-8859-1
;iconv.internal_encoding = ISO-8859-1
;iconv.output_encoding = ISO-8859-1
...
; http://php.net/exif.encode-unicode
;exif.encode_unicode = ISO-8859-15
...
;mssql.charset = "ISO-8859-1"
...
;exif.encode_unicode = ISO-8859-15
Is there any reason why I shouldn't simply replace them all with utf-8?
有什么理由我不应该简单地将它们全部替换为utf-8？

You should set your default_charsetto UTF-8:
您应该将您的设置default_charset为 UTF-8：
default_charset = "utf-8"
(PHP Cookbook may have a typo in it if they ask you to change the default_encoding— I've never heard of it.)
（如果 PHP Cookbook 要求您更改它，则其中可能有错字default_encoding— 我从未听说过。）
You'll also want to make sure that your webserver is set to output UTF-8 if you're going to outputting UTF-8 encoded characters. In Apache this can be set by in the httpd.conf file:
如果您要输出 UTF-8 编码的字符，您还需要确保您的网络服务器设置为输出 UTF-8。在 Apache 中，这可以在 httpd.conf 文件中设置：
AddDefaultCharset UTF-8
As for modifying the iconv, exif, and mssqlencoding settings, you probably don't need to set these (your settings have these commented out anyhow) but it's a good idea to change them all to UTF-8 anyhow.
至于修改 iconv，exif和 mssql编码的设置，你可能并不需要这些设置（设置有这些注释无论如何），但它是一个好主意，他们都更改为UTF-8进不去。

default_charset = "utf-8"
About the other options, do not touch them. Avoid default settings, always explicitly set the encoding of in everything you do
关于其他选项，不要碰它们。避免默认设置，始终明确设置您所做的一切的编码
- database connections,
- reading and writing files,
- converting with iconv.
- 数据库连接，
- 读取和写入文件，
- 用 iconv 转换。
Also, beware of the encoding in which your PHP files are saved, make sure that they are in UTF-8, especially if they contain strings to be displayed or compared.
另外，请注意保存 PHP 文件的编码，确保它们是 UTF-8，尤其是当它们包含要显示或比较的字符串时。

I had a problem on my mysql query that it would not recognize some latin acentuation, so the query would fail. I thought it could be the php file and so on, till i found out that using pdo to call the mysql i had to add the charset. The weird thing is that the previous server i used worked fine!
我的 mysql 查询有一个问题，它无法识别某些拉丁文，因此查询将失败。我以为它可能是 php 文件等等，直到我发现使用 pdo 调用 mysql 我必须添加字符集。奇怪的是我以前使用的服务器运行良好！
$dsn = 'mysql:host=localhost;dbname=retirodo_main;charset=utf8';

To resolve I changed "UTF-8" to "UTF-8" (without the dash), solving the problem instead.
为了解决，我将“UTF-8”更改为“UTF-8”（没有破折号），而是解决了问题。

At htaccess level (.htaccess file) the php directive should be php_value default_charset UTF-8
在 htaccess 级别（.htaccess 文件），php 指令应该是 php_value default_charset UTF-8
