Assuming that you have session_start() at the beginning of both pages?

???? Hitting the enter button will only have variables on that page unless
you do what you call the first or third methods. What do you mean here?

Yes. Create a variable which is an array. Put in the values you want for
each variable as:
theArray['first_var'] = first value;
Then create a single session variable which is $_SESSION['theValues'] =
$theArray and pass that single array via the ?thevalues = $theArray.
At the other end you say:
theArrayReceived = $_GET['thevalues'];
and you have an array that you can get the values via the indexing.
I haven't tried it, but it might also work without the creation of the
session variable step. IOW, say
?thevalues=theArray; and on the other end say theArrayReceived=
$_GET['thevalues'];
When I get home from vacation, I will try it. If you try this and it works
without the session variable step, please let me know.
