Defined two variable variables.  Expected each to have a different value, both ended up with same value. 

$counter = 0;
$$countrycodefinal = "ctrycode" . $counter;
$$aproposfinal = "aproposCitizen" . $counter;
echo ${$countrycodefinal} . "<br>";
echo ${$aproposfinal} . "<p>";

I expected the value of $$countrycodefinal to be "ctrycode0" and the value of $aaproposfinal to be "aproposCitizen0", instead BOTH ended up with the value of "aproposCitizen0".  

I've repeated this several times whenever I use more than one variable variable in the same script.

Looks like you are confused about how variable variables work.

$a = "hello";
$$a = "world";

At this point $hello would be set to "world"

In your example I don't see $countrycodefinal set to anything and thus $$countrycodefinal doesn't make much sense.
