PHP getting variable from another php-file

Question

So I wonder if it is possible to get a variable from a specific php-file when the variable-name is used in multiple php-file  An example is this    lt header gt    lt title gt     lt  php echo  var1    gt    lt  title gt   lt  header gt    page1 php has  var1    page1  page2 php has  var1    page2   footer php should have  lt a href    gt  var1 from page1 lt  a gt  lt a href    gt  var1 from page2 lt  a gt   Ok the example is a bit abstract  but as short as I can make it  I think you get what I am getting at  So it is the  in the footer I am after  Got any solutions

You could also use a session for passing small bits of info. You will need to have session_start(); at the top of the PHP pages that use the session else the variables will not be accessable

page1.php

<?php

   session_start();
   $_SESSION['superhero'] = "batman";

?>
<a href="page2.php" title="">Go to the other page</a>

page2.php

<?php 

   session_start(); // this NEEDS TO BE AT THE TOP of the page before any output etc
   echo $_SESSION['superhero'];

?>
