php中出现“Call to a member function Execute() on a non-object”的问题

?没得办法,学艺不精,今天使用php+adodb进行数据库操作的时候出现“Call to a member function Execute() on a non-object”错误。搞了半天,终于晓得了,在php自定义函数中使用了全局变量,但是没有使用global语句在函数的开头进行声明。php使用变量是不需声明的,因此在函数中使用我想用的那个全局变量的时候,实际上默认创建了一个同名的局部变量,这样,出现错误就是很正常的了。嘿嘿,global一下,下次,你也记住哦~

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

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.
