Should I create functions for packages/libraries that allow optional parameters to accept null as a value?

Should I create functions for packages/libraries that allow optional parameters to accept null?

In this example below, I set the 3rd and 4th parameter as null which will act as the default value.

 
    
myLibrary::myFunction(1, 7, null, null, true);

  

Or is this not a good way to go about creating functions for a package and therefore should not accept null as a parameter value.

 
    
myLibrary::myFunction(1, 7, false, 4, true);

  • As long as optional parameters are placed last, I don't see why not.

    PHP8's named parameters lessen the pain of using a function with optional parameters spread around, but I still stick to that rule.
