PHP, getting variable from another php-file

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:

<header>
 <title>
  <?php echo $var1; ?>
 </title>
</header>

page1.php has $var1 = 'page1' page2.php has $var1 = 'page2'

footer.php should have <a href="">$var1 from page1</a><a href="">$var1 from page2</a>

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 can, but the variable in your last include will overwrite the variable in your first one:

myfile.php

$var = 'test';

mysecondfile.php

$var = 'tester';

test.php

include 'myfile.php';
echo $var;

include 'mysecondfile.php';
echo $var;

Output:

test

tester

I suggest using different variable names.

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'];

?>
