十步解决PHP使用UTF-8编码问题
以前说过如果JS文件不是UTF8会在IE有bug,所以JS代码也要用UTF-8。还有数据库也都要用UTF-8。
php(做为现在的主流开发语言)用UTF-8总结:
- php(做为现在的主流开发语言)文件本身必须是UTF-8编码。不像Java会生成class文件,避免这个问题
- php(做为现在的主流开发语言)要输出头:header(”Content-Type: text/html; charset=UTF-8″)
- meta标签无所谓,有header所有浏览器就会按header来解析
- 所有外围都得用UTF8,包括数据库、*.js、*.css(CSS影响倒不大)
- php(做为现在的主流开发语言)本身不是Unicode的,所有substr之类的函数得改成mb_substr(需要装mbstring扩展);或者用iconv转码(基本上的linux都装了,没装的话download、tar、make、make install,很简单的)
- my.ini:
[MySQL(和PHP搭配之最佳组合)]
default-character-set=utf8
[MySQL(和PHP搭配之最佳组合)d]
default-character-set=utf8
default-storage-engine=MyISAM
在[MySQL(和PHP搭配之最佳组合)d]下加入:
default-collation=utf8_bin
init_connect=SET NAMES utf8 - 在需要做数据库操作的php(做为现在的主流开发语言)程序前面加上
mb_internal_encoding(utf-8); - create table最后边加上ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_bin
- php(做为现在的主流开发语言)MyAdmin/config.inc.php(做为现在的主流开发语言)
$cfg[DefaultCharset] = utf-8;
$cfg[RecodingEngine] = iconv; - php(做为现在的主流开发语言)Admin导出数据时
把"二进制区域使用十六进制显示"的勾去掉
特别郁闷的:文件系统函数不支持UTF-8!

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. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
