php - PHP: How do I best silence a warning about unused variables?

Question

I have an application in which i have to declare (override) methods inherited from an interface. However, these methods have parameters that are not used in my implementation.

class MyImplementation implements ISomething {

  public function foo($bar) {
    // code that does nothing with $bar
    ...
  }

  // other methods
  ...
}

How can I mark $bar as unused in the source code, in C++ this is possible.

In other words, how can I do THIS in PHP?

Answer 1

如果我理解你的问题是正确的，你想在你的 php 脚本中隐藏未初始化变量的错误通知吗？如果是这种情况，您应该更改 php.ini 中的 error_reporting

示例：error_reporting=E_ALL & ~E_NOTICE（显示所有错误，通知除外）
