PHP的函数调用,是通过查表,找到函数名称所对应的函数上。
PHP的函数重载和其他语言不同,它收到的不同个数的参数,实际上都是将其作为一个数组传递给函数。
因此你列举的函数调用,没有参数也能执行,因为其参数数组为空,这一情况是合理的。
PHP函数调用不检查参数个数的匹配。

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.
