PHP中json_encode让Json更懂中文(JSON_UNESCAPED_UNICODE)
我们知道, 用PHP的json_encode来处理中文的时候, 中文都会被编码, 变成不可读的, 类似”\u***”的格式, 还会在一定程度上增加传输的数据量.
echo json_encode("中文"); //Output: "\u4e2d\u6587"这就让我们这些在天朝做开发的同学, 很是头疼, 有的时候还不得不自己写json_encode.而在PHP5.4, 这个问题终于得以解决, Json新增了一个选项: JSON_UNESCAPED_UNICODE, 故名思议, 就是说, Json不要编码Unicode.
看下面的例子:
echo json_encode("中文", JSON_UNESCAPED_UNICODE); //Output: "中文"怎么样, 是不是让大家很开心的改动?
当然, Json在5.4还加入了: JSON_BIGINT_AS_STRING, JSON_PRETTY_PRINT, JSON_UNESCAPED_SLASHES等选项

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.

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,
