In the first instance you are var_dumping the entire array so it shows
the structure/values of the array elements thus showing a reference to a
var that is int(1). In the second instance you are var_dumping a
specific var so you get the value of the var int(1). I'm not sure if
there is a reason that it doesn't show that it is a reference, but the
same is true here:
$x = 1;
$y =& $x;
var_dump($y);
int(1)
