Right, that's what "l" parameter spec is doing, doesn't it? Why convert it manually?

Because it doesn't know the difference between NULL and 0 if it's a long.

And why this difference is important in array_slice()? I don't see anything in manual that says anything about NULLs. Could you explain?

One that doesn't break every script that didn't strictly stay with int over the last 8 years or so.

Errm... I still don't understand. Could you give code example?
