php 判断编码
最近在win的cmd下用 php 的 cli 调试程序总是出来乱码; 研究一番才知道原来是 cmd 只支持 gbk 的显示,如果 cli 吐出来的数据是 utf-8 编码的就出乱乱码,最后使用 mb_convert_encoding 转码, 在吐出来之前进行一次转码就可以了; 研究过程中看到一函数,

研究一番才知道原来是 cmd 只支持 gbk 的显示,如果 cli 吐出来的数据是 utf-8 编码的就出乱乱码,最后使用 mb_convert_encoding 转码,
在吐出来之前进行一次转码就可以了;
研究过程中看到一函数,貌似精确度不能达到 100% 不过也不失为解决问题的一程序办法;
function is_utf8($word) { if (preg_match("/^([".chr(228)."-".chr(233)."]{1}[".chr(128)."-".chr(191)."]{1}[".chr(128)."-".chr(191)."]{1}){1}/",$word) == true || preg_match("/([".chr(228)."-".chr(233)."]{1}[".chr(128)."-".chr(191)."]{1}[".chr(128)."-".chr(191)."]{1}){1}$/",$word) == true || preg_match("/([".chr(228)."-".chr(233)."]{1}[".chr(128)."-".chr(191)."]{1}[".chr(128)."-".chr(191)."]{1}){2,}/",$word) == true) { return true; } else { return false; } }

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.
