如何在php中获取字符串的确切长度? [英] how to get the exact length of a string in php?

问题描述

我的奇怪结果是:

strlen("òàùè")

如何正确计数带有 no-ascii 字符的字符串?

How can I count correctly string with no-ascii characters?

我也查看了mb_strlen()，但不能解决问题.

I also looked at mb_strlen() but does not solve the problem.

谢谢

推荐答案

mb_strlen将

返回字符串$ str中的字符数.字符编码为$ encoding .一个多字节字符计为1.

Return the number of characters in string $str having character encoding $encoding. A multi-byte character is counted as 1.

您的内部编码可能未设置为utf-8，所以

Your internal encoding is likely not set to utf-8, so do

echo mb_strlen('òàùè', 'utf8');

或全局设置utf8:

mb_internal_encoding('utf8');

然后做

echo mb_strlen("òàùè");

会给出4(演示)
