关于转码问题

Jun 23, 2016 pm 02:24 PM

import 503-9256962-4382268 Failure -1
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '054-246-0787','JPS0001' ,'0243-BK', 'iphone 4 用臂? (黑色)', '1', '???' at line 1

我进行了转码也报以上错误,我的转码函数:
$recipient_name=mb_convert_encoding(addslashes($u[16]), 'UTF-8','UTF-8,sjis-win,eucjp-win');



echo base64_encode($u[16])结果:mGiRg4xc

我输出转码后的结果是对的:"??圭",但是不知道写入数据库就会报错,我发现只有包含"圭"的都会写入数据库失败。

请问有什么办法解决这个问题??

数据库字段编码不支持

谷口 圭\
??圭\

我重新输出,名字都带了"\",是不是这个原因呢??请问怎么解决?

$s = base64_decode('mGiRg4xc');echo '字符集 ', mb_detect_encoding($s, 'UTF-8,sjis-win,eucjp-win'), '<br>';echo '16进制内码 ', bin2hex($s), '<br>';echo 'utf-8 ', $t = mb_convert_encoding($s, 'utf-8', 'UTF-8,sjis-win,eucjp-win'), '<br>';echo '16进制内码 ', bin2hex($t);
Copy after login

字符集 JIS-win
16进制内码 986891838c 5c 这个 5c 是 \ 的16进制内码
utf-8 ??圭
16进制内码 e9b7b2e5b7a3e59cad

所以你需要
$recipient_name=mb_convert_encoding($u[16], 'UTF-8','UTF-8,sjis-win,eucjp-win');
而不是
$recipient_name=mb_convert_encoding(addslashes($u[16]), 'UTF-8','UTF-8,sjis-win,eucjp-win');
即不能用 addslashes 做转义处理

转义 ' 需要用 str_replace("'", "\'", $s) 

xuzuning 大大:
     不转义可以了 ,不过有个问题还想请教一下,因为我插入的内容是很多国家的,如果不转义的话,不知道哪个国家的人名里面包含一些特殊,不转义的话有可能一样写入失败,请问这种情况有办法解决吗?

  

先转码,再转义
