连接到数据库后尝试调用mysql_set_charset('utf8');.我认为这与执行SET NAMES查询相似，但是由于PHP手册指出建议在SET NAMES查询上使用该功能，所以我会尝试一下.

Try calling mysql_set_charset('utf8'); after connecting to the database. I think it's similar to executing a SET NAMES query, but since the PHP manual says using that function over a SET NAMES query is recommended, I'd try it.

此外，在显示内容时，您可以尝试echo htmlentities($string, ENT_COMPAT, 'UTF-8');

Also, when you display your content, you could try echo htmlentities($string, ENT_COMPAT, 'UTF-8');
