ThinkPHP3.1新特性之动态设置自动完成和自动验证示例_php实例
以往在ThinkPHP3.1版本之前,如果需要设置自动验证或者自动完成,一般来说必须定义在模型中,或者通过setProperty方法动态设置属性来完成,这样做的缺点是不太方便动态改变和调整。
ThinkPHP3.1版本在模型类中增加auto和validate两个连贯操作,用于动态设置自动完成和自动验证规则,现在可以在Action中使用:
$validate = array( array('verify','require','验证码必须!'), array('name','','帐号名称已经存在!',0,'unique',1), ); $auto = array ( array('password','md5',1,'function') , array('create_time','time',2,'function'), ); M('User')->auto($auto)->validate($validate)->create();
其中$auto和$validate变量的规范和模型类的_auto和_validate属性的定义规则一致,而且还可以支持函数调用(由于PHP本身的限制,在类的属性定义中不能调用函数)。
auto和validate方法必须在create方法之前被调用。
通过这一改进,你完全可以通过M方法实例化模型类后使用动态设置完成自动验证和自动完成操作,不必再依赖D方法了。

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.
