Hi !
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 ;)
