在echo中使用$ page title

Question

I want this to work, it doesn't currently, so, if its possible, what do I need to change:

<?php echo $page_title_LEADER; ?>

In the config file I have

define('ENGLAND_LEADER', 'Bob Smith:');
define('SPAIN_LEADER', 'Stan Smith:');

which when I use:

<?php echo ENGLAND_LEADER; ?>

works fine as you would expect, what I'm trying to do is use the page title to auto fill the COUNTRY name part of COUNTRY_LEADER, so I don't have to manually change the name of the country each time.

NB I do have the $page_title set in the page

Answer 1

You can use the constant function for this

<?php echo constant($page_title . '_LEADER') ?>
