php mb_substr()函数截取中文字符串应用示例,

substr()函数用来截取字符串,但是对于中文字符会出现问题,而mb_substr()和mb_strcut这两个函数可以,用法与substr()相似,只是在函数最后要加入多一个参数,以设定字符串的编码,使用这两个函数需要在php.ini中把php_mbstring.dll打开。

<&#63;php 
header("content-type:text/html; charset=utf-8");
$string = "你好我好大家好";
echo strlen($string).'</br>';
echo mb_substr($string,0,4,'utf-8').'...</br>';
echo mb_strcut($string,0,4,'utf-8').'...';
&#63;>
Copy after login

输出的结果:

21
你好我好...
你...

从上面的例子可以看出,mb_substr是按字来分割字符,而mb_strcut是按字节来分割字符,但是都不会产生半个字符的现象。
