You can use session to do this

 session_start();

 $_SESSION["myname"] = $_GET['myname'] ;

 $_SESSION["age"] = $_GET['age'] ;

and then you can access this SESSION variables on any page.

on your page where u want to access age, do like this

$age=$_SESSION["age"] ;

You can just pass the variables again using the same method, passing them through the URL or put them in a session so they can be accessed anywhere, at least while the session is still active.

For example:

<?php

session_start();

$_SESSION['myname'] = $_GET['myname'];
$_SESSION['age'] = $_GET['age'];
$_SESSION['fav_color'] = $_GET['fav_color'];
$_SESSION['fav_fruit'] = $_GET['fav_fruit'];

Why don't you use PHP session variables. Bascially, PHP session variables could be accessed anywhere inside the application.

session_start();
$_SESSION["myname"]    = $_GET['myname'];
$_SESSION["age"]       = $_GET['age'];
$_SESSION["fav_color"] = $_GET['fav_color'];
$_SESSION["fav_fruit"] = $_GET['fav_fruit'];

To Get the entire session variables/values in your third page:

echo '<pre>';
print_r($_SESSION);

You can use like below:

On first page you used this URL:

<a href="page2.php?var_one=1&var_two=2&var_three=3">Go to second page</a>

Similarly on second page you can use below URL:

<a href="page3.php?var_one=1&var_two=2&var_three=3">Go to third page</a>

Let me know if it worked out for you. If details needed knock me.
