Re: [PHP4BETA] problem passing arrays by reference using array_walk

Bear in mind that the example I posted was a simple example to illustrate the problem. In reality, I want to do something much more complex to items in Array2 depending on what happens as I walk through Array1, but I need it to happen to the real Array2, not a local copy of it.
