数据库中不乱码?你用什么工具查看的

数据库中不乱码?你用什么工具查看的


用Mysql Front 
乱码字段的类型是longblob的
查询之后显示
[1] => array(7) {
    ["question_index"] => string(1) "2"
    ["question_content_text"] => string(21) "小鸟会不会飞?"
    ["question_type"] => string(9) "问答题"
    ["answer"] => string(16)  "????????????"
    ["user_answer"] => string(1) "2"
    ["question_score"] => string(2) "10"
    ["user_score"] => string(1) "0"
  }

从长度 16 上看,你的 answer 字段不是 utf-8 编码的吧?

echo base64_encode($ar[1]['answer']); 贴出结果

从长度 16 上看,你的 answer 字段不是 utf-8 编码的吧?

echo base64_encode($ar[1]['answer']); 贴出结果


echo base64_encode($ar[1]['answer']);之后出现:
v8nE3Lvho6y/ycTcsru74Q==

$s = base64_decode('v8nE3Lvho6y/ycTcsru74Q==');var_dump($s);
Copy after login
string(16) "可能会,可能不会" 
是 gbk 编码的

你需要在查询前执行 set names utf8 指令
或在输出前转码
