PHP insert headercontent-type:text/html;charset='utf-8 and error_reporting
1.header
PHP file insert header("Content-type: text/html; charset=utf-8");
equivalent to
1:E_ERROR 致命的运行错误。错误无法恢复,暂停执行脚本。 2:E_WARNING 运行时警告(非致命性错误)。非致命的运行错误,脚本执行不会停止。 4:E_PARSE 编译时解析错误。解析错误只由分析器产生。 8:E_NOTICE 运行时提醒(这些经常是你代码中的bug引起的,也可能是有意的行为造成的。) 16:E_CORE_ERROR PHP启动时初始化过程中的致命错误。 32:E_CORE_WARNING PHP启动时初始化过程中的警告(非致命性错)。 64:E_COMPILE_ERROR 编译时致命性错。这就像由Zend脚本引擎生成了一个E_ERROR。 128:E_COMPILE_WARNING 编译时警告(非致命性错)。这就像由Zend脚本引擎生成了一个E_WARNING警告。 256:E_USER_ERROR 用户自定义的错误消息。这就像由使用PHP函数trigger_error(程序员设置E_ERROR) 512:E_USER_WARNING 用户自定义的警告消息。这就像由使用PHP函数trigger_error(程序员设定的一个E_WARNING警告) 1024:E_USER_NOTICE 用户自定义的提醒消息。这就像一个由使用PHP函数trigger_error(程序员一个E_NOTICE集) 2048:E_STRICT 编码标准化警告。允许PHP建议如何修改代码以确保最佳的互操作性向前兼容性。 4096:E_RECOVERABLE_ERROR 开捕致命错误。这就像一个E_ERROR,但可以通过用户定义的处理捕获(又见set_error_handler()) 8191:E_ALL 所有的错误和警告(不包括 E_STRICT) (E_STRICT will be part of E_ALL as of PHP 6.0)
Any number of the above options can be connected with "OR" (using OR or |), so that all required error levels can be reported.
For example, the following code turns off user-defined errors and warnings, performs certain operations, and then returns to the original error level:
php //禁用错误报告error_reporting(0); //报告运行时错误error_reporting(E_ERROR | E_WARNING | E_PARSE); //报告所有错误error_reporting(E_ALL); ?>The above introduces the PHP insertion of headercontent-type:text/html;charset="utf-8 and error_reporting, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.

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,
