This is not an answer, but it is a solution. I don't ever rely on
include_once. If someone else uses my include files they may not use
include_once. Instead I use the old C/C++ trick of defines:
<?php
if (!defined('SOME_INCLUDE')) {
define('SOME_INCLUDE', TRUE);
// Place code here
}
?>
I use the following structure for creating unique constants to prevent
collisions:
{projectname}_{classname}( include ? _INC:)
A global class outside my projects:
_CLASS_NAME
The class FooBar in my Rule The World project:
RULE_THE_WORLD_FOO_BAR
The config include in my Rule The World project:
RULE_THE_WORLD_CONFIG_INC
