php字符转码 utf-8 to gb2312

php utf-8 character I of transfer Transcode meet question project

 

遇到php的转码问题,差点没折磨死我,无论我调用项目中的那些函数,都白做功夫,可能是掉错了,不知道,到网上找了好多,终于,终于,被我找到了:

 

iconv("UTF-8","gb2312",$username);

 

就是这个,我遇到的问题是这样的:

 

我要利用session的username,在config.php页,我可以得到,赋值给变量

 

$username=$_SESSION['user_name'];

 

$fromuser=$username;

 

然后要把这个值传到另一个页,再保存到数据库,从config.php到newmessage.php页就遇到麻烦了,

 

 

按上面的写法,值传到newmessage.php页就出现乱码了。说一下,我的整个系统是utf-8编码,而

 

config.php是gb2312(我也不清楚为什么把config.php编码直接改成utf-8就直接出现乱码,反正得是

 

gb2312或是gbk的),所以就需要转码了,把username在config.php直接转成gb2312,费了九牛二虎之力

 

好不容易找到这个疯狂代码,我的写法是这样的:

 

$fromuser=iconv("UTF-8","gb2312",$username);

腾讯的IP地址API接口地址:http://fw.qq.com/ipaddress

 

返回的是数据格式为:var IPData = new Array(“114.218.183.139″,””,”江苏省”,”苏州市”);

 

使用JS代码进行调取:

04    $ip=str_replace('"',' ',$ip);

05    $ip2=explode("(",$ip);

06    $a=substr($ip2[1],0,-2);

07    $b=explode(",",$a);

08    return $b;

09    }

10    $ip=getIpPlace();

11    print_r($ip);

12    ?>

处理后输出的是一个数组。
