微信支付： package中的参数partner或prepay_id为空
百度这个问题，有人说是商户支付号写错，说支付号时8位的，可是我只找到10位的
我将prepay_id打印出来是空，我百度无果，故来此地，请各位指点下

我自己的问题，KEY写错 --真恶心自己
顺便，总结下 做微信支付的几点感受
1.有4个参数时是必要的
APPID -- 公众号唯一标识
MCHID -- 商户支付号
KEY -- 这个需要自己去设置 在商户平台-账号设置-API安全
APPSECRET -- 可以在账户信息中找到
要实现支付功能，除了上面 我认为还有2个比较关键的地方
1.设置授权目录 例：収起请求的页面 url为 http://www.xxx.com/weixin/pay/payment.php?XXXXX，则
填写的目录应该为 http://www.xxxcom/weixin/pay/。
2.实现功能 其中要获取用户的code值，如果是网页跳转形式 要在 微信公众平台-开发者中心-配置项-网页授权获取用户基本信息 配置下你的域名
其他的问题 暂时没遇到

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,

Apr 03, 2025 am 12:04 AM
Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

Explain the match expression (PHP 8 ) and how it differs from switch.
Apr 06, 2025 am 12:03 AM
In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.
The difference between H5 and mini-programs and APPs
Apr 06, 2025 am 10:42 AM
H5. The main difference between mini programs and APP is: technical architecture: H5 is based on web technology, and mini programs and APP are independent applications. Experience and functions: H5 is light and easy to use, with limited functions; mini programs are lightweight and have good interactiveness; APPs are powerful and have smooth experience. Compatibility: H5 is cross-platform compatible, applets and APPs are restricted by the platform. Development cost: H5 has low development cost, medium mini programs, and highest APP. Applicable scenarios: H5 is suitable for information display, applets are suitable for lightweight applications, and APPs are suitable for complex functions.

How can you prevent a class from being extended or a method from being overridden in PHP? (final keyword)
Apr 08, 2025 am 12:03 AM
In PHP, the final keyword is used to prevent classes from being inherited and methods being overwritten. 1) When marking the class as final, the class cannot be inherited. 2) When marking the method as final, the method cannot be rewritten by the subclass. Using final keywords ensures the stability and security of your code.
