推荐答案
您需要考虑以下几点:
- Check that data in the DB is being stored as UTF-8
- Check that the client connection to the DB is in UTF-8 (for example, in mysql see: http://www.php.net/manual/en/mysqli.character-set-name.php)
- Make sure that the page has it's content-type set as UTF-8 [you can use
header('Content-Type: utf-8');
] - Try setting the internal encoding, using
mb_internal_encoding("UTF-8");
- Use
mb_substr
instead of array index notation
