Class static member accessed via instance

Reports references to static methods and fields via a class instance rather than the class itself.

Even though referring to static members via instance variables is allowed by PHP, this makes the code confusing, as the reader may think that the result of the method depends on the instance.

The quick-fix replaces the instance variable with the class name.

Example:

  class StaticClass {
    public static function someStaticFunction(): int
    {
        return 3;
    }

  }

  $var = new StaticClass
  $var::someStaticFunction();

After the quick-fix is applied:

StaticClass::someStaticFunction()
