PHP mb_substr()无法正常工作? [英] PHP mb_substr() not working correctly?

问题描述

此代码

print mb_substr('éxxx', 0, 1);

打印一个空白:(

应该打印第一个字符é.但是，这似乎可行:

It is supposed to print the first character, é. This seems to work however:

print mb_substr('éxxx', 0, 2);

但这是不对的，因为(0，2)表示2个字符...

But it's not right, because (0, 2) means 2 characters...

推荐答案

尝试将编码参数传递给mb_substr，例如:

Try passing the encoding parameter to mb_substr, as such:

print mb_substr('éxxx', 0, 1, 'utf-8');

永远不会自动检测到编码.

The encoding is never detected automatically.
