php字符转码 utf-8 to gb2312
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);

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
