Manually setting register_globals

This value is generally set in the httpd.conf (server) file, which is generally not accessible to users on shared hosting packages. So, here are a few ways to get around this.

In a ‘.htaccess’ file, stored in web root:
php_value register_globals on

or in a ‘php.ini’ file, also stored in the web root:
register_globals = on
