PHP莫若ASP好使的三个地方
PHP不如ASP好使的三个地方
学PHP一段时间了,感觉PHP整体功能比ASP强大得多,特别是提供的函数及函数参数的灵活性比ASP起码多一个数量级。但PHP有些地方不如ASP好使。
(1)设置Cookie时,setcookie函数前面不能有任何HTML代码输出,这实在很不方便,为此,我以为使用ob_start()打开缓冲区后能解决该问题,但似乎没用,写一句ob_start()只能减少一条警告而已。
(2)设置永久Cookie时,setcookie函数为每个Cookie变量都要设置第三个(expire)参数,如果每个Cookie变量的过期时间相同,则这样明显要重复写很多次expire参数,而ASP却可以通过使用多值Cookie,为所有多值Cookie设置一个共同的expire。
(3)PHP 添加、删除、修改记录时,只能用执行SQL语句的方法,而ASP除了用这种方法外,还可以使用rs.addnew,rs.update,rs.delete等记录集对象提供的方法,而用这种方法能使程序明显更清晰些。
不知上面几点是我说得对,还是我孤陋寡闻不知道有更好的解决方法,欢迎各位同仁来纠正我的观点哦。
当然PHP最不好使的地方还是:老是要输入$符,而这个符号很不好输入,严重影响我输入代码的速度。

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,

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.

What are the magic methods of PHP?
