You can't increment $foo[$key1] without knowing current value of $foo[$key1] - you need to read it first. But you don't need to know previous value (or its type) to overwrite it (it does not matter what is $foo[$key1] value if you do $foo[$key1] = 1 - it works similar to $foo = 1); Regards, Robert Korulczyk
