Can I load a library class without creating an instance of it? [SOLVED] - El Forum - 07-25-2011

First post! Yay!
Ok, here is the deal: I try to save as much memory as I can in my app, and to do so, I use refferences a lot. In order to count the instances of my objects, all my library classes have these attributes and functions:
Code:
private static $instances=0;
public __construct(){
ClassName::$instances++;
//Rest of constructor
}
public __destuct(){
ClassName::$instances--;
//Rest of destructor
}The following code shows me that an instance is created at load time
Code:
$this->load->library('ClassName');
echo "Instances of ClassName in memory: ".ClassName::$instances;
//Outputs: Instances of ClassName in memory: 1Soooo, here are my questions:
1) I know that just one extra instance is no big deal, but it bugs me that it's there... Can I load the class without creating it, or even destroy it somehow?
2) This causes problems when I want to auto load a class that has parameters in it's constructor, as I don't see a way to pass parameters in the Autoload... To resolve i did the following, but I don't like it much...
Code:
<?php if (!defined('BASEPATH'))
exit('No direct script access allowed');
class ClassName {
public function __construct($params=NULL) {
if (!$params) return;
//Rest of the constructor...
}
}
?>Is there a better way to autoload classes with parameters?
Ok, that's enough for now, thanks for your time!

1) Not using the loader. You can do this by including/requiring the files like you would outside of CI.
2) Nope. To get around this you can create a MY_Controller and load what you need there (with or without parameters).

Heh! I got so excited about CI, i totally forgot I could simply inlude_once the classes I needed! Thanks!
