mb_internal_encoding — 设置/获取内部字符编码
$encoding
= mb_internal_encoding()
] )设置/获取内部字符编码
encoding
encoding
字符编码名称使用于 HTTP 输入字符编码转换、HTTP 输出字符编码转换、mbstring 模块系列函数字符编码转换的默认编码。
You should notice that the internal encoding is totally different from the one for multibyte regex.
如果设置了 encoding
,则成功时返回 TRUE
, 或者在失败时返回 FALSE
。
In this case, the character encoding for multibyte regex is NOT changed.
如果省略了 encoding
,则返回当前的字符编码名称。
Example #1 mb_internal_encoding() 例子
<?php
mb_internal_encoding ( "UTF-8" );
echo mb_internal_encoding ();
?>

Note that mb_internal_encoding is not necessary in PHP 5.6

i noticed that setting mb_internal_encoding('UTF-8') in my global site config.inc.php, doesn't work in my classes : it reverse back to ISO-8859-1.
Adding the call to the constructor of my top site class resolve this.

In response to mortoray at ecircle-ag dot com:
The characters display fine as long as you set the Encoding to something more "Latin 1" compatible (i.e. US-ACSII, ISO-8859-1, ISO-8859-1, or Windows 1252). PHP.net auto-detects to UTF-8
[#5] Joachim Kruyswijk [2006-05-25 00:52:29]
Especially when writing PHP scripts for use on different servers, it is a very good idea to explicitly set the internal encoding somewhere on top of every document served, e.g.
mb_internal_encoding("UTF-8");
This, in combination with mysql-statement "SET NAMES 'utf8'", will save a lot of debugging trouble.
Also, use the multi-byte string functions instead of the ones you may be used to, e.g. mb_strlen() instead of strlen(), etc.

To previous example, the PHP notes don't appear to support umlauted characters so there are question marks (?) there instead of what should be umlauated oue. Just substitute any high-order/accented character to see the effect.
