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。

我也刚学php,慢慢适应吧~~~
1、为什么没用,用ob_start() 完全是可以的。

(1)为什么没用?ob_start() 只阻止了其后的直接输出,但之前的输出依然会产生影响
(2)ASP的多值Cookie 读取起来是很麻烦的,还不如单个设置
(3)ASP 的数据库操作是借助 adodb 组件进行的,就好比在 php 中引入一个类。至于组件、类提供了什么功能,与语言本身并没有什么关系
诚然,php的确也有很多不尽人意的地方。如果没有,就真的没了asp的生存空间了
php还是很流行的
asp这么老的技术现在还有公司用吗,asp。net差不多

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
