Supporting legacy code, using global variables and register_globals with PHP 5.4.x
Recently we ran into some issues with some of our old sites that are relying on the register_globals for variable access after upgrading to PHP 5.4 which wisely no longer supports this kind of setup. Using globals in this fashion is a horrible practice, but sometimes you gotta maintain some legacy code.
To use global variables you can add a line of code to htaccess that will run a “globalizer” file before loading the main page on every page load and extract the required variables.
<!--?php extract($_SERVER); extract($_SESSION); extract($_REQUEST); extract($_FILES); extract($_ENV); ?-->
# Relative path to the 'globalizer' file, in this example it's in webroot php_value auto_prepend_file ./globalizer.php
Hope this helps.
