回复讨论(解决方案)
他是 16 字节的二进制数据，读出来应该是个串
你给我看看，才好说怎么做
比如读出后保存在变量 $id 中
你就 echo base64_encode($id); 贴出结果
V+mLfrZqsEa+dAAJhxD9Yw==
我有你的方法输出后就是这个结果。
版主还在吗？帮我看看啊，我这就差这一点点关键的了。
$id = base64_decode('V+mLfrZqsEa+dAAJhxD9Yw==');echo join('-', unpack('H8a/H4b/H4d/H4e/H*f', $id));对对，谢谢版主，能解释一下吗？我没看懂，麻烦了。
uniqueidentifier类型是一个32字节长的二进制数据
一般显示为5节十六进制数（8,4,4,4,12）
将二进制数据转换成十六进制表示的方法有多种
这里我使用了 unpack 函数
转换时的格式串 H8a/H4b/H4d/H4e/H*f 的含义为
H8a 取8个字节转换成十六进制表示，放在键名 a 中
H4b 取4个字节转换成十六进制表示，放在键名 b 中
H4d 取4个字节转换成十六进制表示，放在键名 d 中
H4e 取4个字节转换成十六进制表示，放在键名 e 中
H*f 剩余的转成十六进制表示，放在键名 f 中
/ 是分节符
谢谢！十分感谢。
利用bin2hex()函数输出即可

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
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,
