使用记事本编辑php文件导致的一点问题
今天修改自己在sae上面的WordPress文件的时候,因为没在自己的机器上操作,就使用了记事本,结果提交上去就报错了。
报错内容是 Cannot modify header information - headers already sent by (output started a ,下面是报错的界面:
当然这个sae还没有通过认证,而且只是临时测试用的,过几天就没了。这里就说一下主要原因吧,这里他说在functions.php文件输出了东西,而且这个输出在调用header()之前输出的。
其实这个问题主要就是使用记事本编辑产生的,我这里是进行了一次替换,替换为了源文件,然后就下载了一个notepad++来进行编辑。
通常这种报错的原因还有可能是在输出内容之前有缓存的产生,我们需要设置一下php.ini文件,把output_buffering设置为on即可。

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,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
