You can change mbstring.language to whatever language you are using with. <a href="http://marc.info/?l=php-i18n&amp;m=107060346828334&amp;w=2" rel="noreferrer">(Source)</a>

language

<pre><code>; language for internal character representation.
mbstring.language = Neutral ; Set default language to neutral(UTF-8) (default)
mbstring.language = English
mbstring.language = Japanese
mbstring.language = Korean ;For Korean market later
</code></pre>

http_input

<pre><code>; http input encoding.
mbstring.http_input = pass
mbstring.http_input = auto
mbstring.http_input = UTF-8
mbstring.http_input = UTF-8, SJIS, EUC-JP
</code></pre>

http_output

<pre><code>; http output encoding. mb_output_handler must be
; registered as output buffer to function
mbstring.http_output = pass
mbstring.http_output = UTF-8
</code></pre>

encoding translation

<pre><code>; enable automatic encoding translation accoding to
; mbstring.internal_encoding setting. Input chars are
; converted to internal encoding by setting this to On.
; Note: Do _not_ use automatic encoding translation for
; portable libs/applications.
mbstring.encoding_translation = On
</code></pre>

blocks|key|326492|text|重点是支持不同的字符集编码。有各种各样的编码(ASCII、ANSI、UTF-8等)，每种编码都有不同的字符集和每个字符的字节数。您查看的设置指定了不同PHP函数的默认编码。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|326493|PHP提供了许多函数来帮助您正确处理这些不同的编码。有关示例，请查看mb_strlen()与strlen()。|326494|简单的答案是，除非您正在本地化应用程序的文本，或者使用不同的编码与系统通信(包括您的数据库！)，否则您可能不需要担心这一点。|326495|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

The point is to support different character set encodings. There are a wide variety of encodings (ASCII, ANSI, UTF-8, etc) and each one has different character sets and number of bytes per character. The settings your looking at specify default encodings for different PHP functions.

PHP supplies a number of functions that help you deal with these different encodings properly. For an illustration, check out mb_strlen() vs strlen().

Short answer is, unless you're localizing your application's text, or communicating with systems with different encodings (your database included!), you probably don't need to worry about it.

blocks|key|3293609|text|我认为这个例子中的演示已经解释了所有的事情：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3293610|http://fr2.php.net/manual/en/function.mb-internal-encoding.php#53265|offset|length|3293611|虽然它没有在其中使用，但你可以推断出mbstring.http_input的用法。|style|CODE|3293612|entityMap|0|LINK|mutability|MUTABLE|url^0|0|0|1W|0|0|I|J|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@$D|S|E|T|1|U]]|A|$]]|$1|F|3|G|5|6|7|V|8|@$D|W|E|X|H|I]]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|K|$L|$5|M|N|O|A|$P|C]]]]

I think everything is explained by the demonstration in this example:

<a href="http://fr2.php.net/manual/en/function.mb-internal-encoding.php#53265" rel="nofollow">http://fr2.php.net/manual/en/function.mb-internal-encoding.php#53265</a>

Though it's not used in it, you can deduce the use of <code>mbstring.http_input</code>.

I'm trying to figure out exactly what these php.ini settings do. What happens when they're set to different values? When are they necessary? When are they harmful?

<ul>
<li><a href="http://us3.php.net/manual/en/function.mb-language.php" rel="noreferrer">mbstring.language</a></li>
<li><a href="http://us3.php.net/manual/en/function.mb-http-input.php" rel="noreferrer">mbstring.http_input</a></li>
<li><a href="http://us3.php.net/manual/en/function.mb-http-output.php" rel="noreferrer">mbstring.http_output</a></li>
<li>mbstring.encoding_translation</li>
</ul>

As usual, the <a href="http://www.php.net/manual/en/mbstring.configuration.php" rel="noreferrer">PHP manual</a> is less than helpful.

EDIT: Just to clarify, I understand how character encodings work, and I understand how PHP's multi-byte functions differ from their single-byte counterparts. I'm looking for specifics on what the above settings do.

EDIT 2: OK, it looks like they actually do provide more documentation than just the <a href="http://www.php.net/manual/en/mbstring.configuration.php" rel="noreferrer">page on runtime configuration</a>, which just has one-line summaries. The first three of these have similarly-named functions, and there are more details on the pages that describe the function versions. I added links above.

EDIT 3: Adding a bounty. I'm looking for specific details on exactly what these settings do, especially the last three. What do they convert from and to, and when do they do it?

What do these PHP mbstring settings do?

我正在尝试弄清楚这些php.ini设置到底是做什么的。当它们被设置为不同的值时会发生什么？它们什么时候是必要的？它们在什么时候是有害的？mbstring.encoding_translation像往常一样，没有什么用处。PHP EDIT：为了澄清，我理解字符编码是如何工作的，我也理解的多字节函数与单字节函数的区别。我正...
