As you passed $a in reference while defining $v, the '3' index of $a was defined. Furthermore, you didn't at any time affect a value to that '3' index of $a, but it exists because he was invocated once... So the result of your print_r isn't odd ;) Maybe you know that very well and your question was infinitely more technical, but for that I can't answer anymore ;) Ace
