Another possibility would be to add the values as variables in a file and
then include() that file in scripts where the value(s) need to be used.
For example:
variables.inc
<?php
$thisvar = 3;
$thatvar = 7;
?>
And then in any script that needs to know these values something like:
<?php
//.....
include 'variables.inc';
$new_thisvar = $thisvar * 3;
//.....
?>
Add other ingredients to taste :-)
