Heres where the problem lies. Each component is in a separate file, and when
I run the script, I get an arror saying I cant re-define the classes.
Which makes me believe that the include_once() function is trying to include
the other components even though they are already included. So, does that
mean that include_once() only works right when it is used in the same file?
It wont recognise that an include was already included in another include?
Have I confused you yet? I am.
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

[PHP] include_once() isnt!
Ive programmed with C/C++ for years and have recently started to dabble in PHP. Ive written a multi-part script for a friend and Ive run into a problem. Ive got 14 include files 3 of which are basic components that may or may not be used by other components. One is an authorisation class, another is a Dbase clas (For MySQL) and another is a file system component. Now heres the problem. My authorisation component uses the DBase component. Some of my other components use the DBase component only some of the time and the Auth and DBase components some of the time and the Auth component some of the time. SO... In the Auth component ive included (via include_once()) the DB component, because it needs it. NOW... in other modules Ive included (via include_once()) the auth, DB, and gallery components. Heres where the problem lies. Each component is in a separate file, and when I run the script, I get an arror saying I cant re-define the classes. Which makes me believe that the include_once() function is trying to include the other components even though they are already included. So, does that mean that include_once() only works right when it is used in the same file? It wont recognise that an include was already included in another include? Have I confused you yet?
