本文为大家讲解的是一个php截取中文字符串乱码方法,感兴趣的同学参考下.

GBK编码截取示例


$str = '我是谁';  //gbk编码的字符串
echo mb_substr($str, 0, 1, 'gbk'); //输出 我

mb_substr方法比substr多一个参数,用来指定字符串编码。

utf-8编码截取示例

[code]
$str = '我abc是谁';  //utf-8编码的字符串
echo mb_substr($str, 0, 2, 'utf-8'); //输出 我a
[/code

中英混合也完全没有问题。

友情提示

使用的时候要注意php文件的编码,和网页显示时的编码。

使用这个mb_substr方法要事先知道字符串的编码,如果不知道编码,就需要判断,mbstring库还提供了mb_check_encoding来检验字符串编码,但还不完善。
