php - str_replace this character: ö

Question

I am trying to do a str_replace on the following line:

team 4 -1ööööö57167168

I've been able to do it in the past just by doing this:

str_replace("ööööö", " ",trim($line));

The desired outcome should be team 4 -1 57167168

However, now that I'm trying to do it in a Codeigniter application, it fails to replace it and I'm not sure what to try.

Is this an encoding config issue with Codeigniter? How can I get it to replace correctly?

Answer 1

在此处查看多字节字符串函数http://php.net/manual/en/ref.mbstring.php，特别是 mb_str_replace。

请注意，ö 可以用多个字符集表示，因此请确保匹配正确的字符集！

Answer 2

使用 utf8_encode() 和 utf8_decode()，PHP 不是 UTF8 原生语言！
