将PHP默认编码设置为utf-8?

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_encoding configuration to utf-8.

在“PHP Cookbook”中，他们说(p.589)要正确地将传出数据的字符编码设置为utf-8，需要将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中找不到这个配置。我应该简单地添加一行，写上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;default_charset = "iso-8859-1"正如您所看到的，现在它没有被激活。我应该删除分号并将其设置为“utf-8”吗?这能解决默认编码吗?

I also found other encoding directives that I don't know what to do about:

我还发现了其他编码指令，我不知道该怎么办:

[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?

为什么我不能简单地用utf-8替换它们呢?

You should set your default_charset to UTF-8:

您应该将default_charset设置为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.)

(如果他们要求您更改default_encoding, PHP Cookbook中可能有一个输入错误——我从未听说过它。)

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:

如果要输出UTF-8编码的字符，还需要确保webserver设置为输出UTF-8。在Apache中，这可以在httpd中设置。配置文件:

AddDefaultCharset UTF-8

As for modifying the iconv, exif, and mssql encoding 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编码设置，您可能不需要设置这些(您的设置已经注释掉了这些)，但最好还是将它们全部更改为UTF-8。

About the other options, do not touch them. Avoid default settings, always explicitly set the encoding of in everything you do

关于其他选择，不要碰它们。避免默认设置，始终显式地设置所有操作的编码

converting with iconv.
与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，要注意保存PHP文件的编码，确保它们在UTF-8中，特别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acentuation，因此查询将失败。我认为它可以是php文件等等，直到我发现使用pdo调用mysql时我必须添加字符集。奇怪的是，我之前使用的服务器运行得很好!

$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.

为了解决这个问题，我将“UTF-8”改为“UTF-8”(没有破折号)，从而解决了这个问题。

changing from *default_charset = "utf-8"* to *default_charset = "iso-8859-1"* works for me ( i use Apache web server and Linux OS). for some reasons when i use utf-8, some characters don't render well. They either change to some square sign or question mark depending on the web browser used.

从*default_charset = "utf-8"*更改为*default_charset = "iso-8859-1"*对我来说是可行的(我使用Apache web服务器和Linux OS)。由于某些原因，当我使用utf-8时，有些字符不能很好地呈现。根据所使用的web浏览器，它们要么更改为某个方形符号，要么更改为问号。
