Vars in models

[eluser]xwero[/eluser]
If you want to store data that has to be used by multiple methods you add variables to the beginning of the class. If they are public (all var defined variables are) you can change them form outside the class if you wanted to

Code:

$this->image_lib->width = 200;
// is the same as
$config['width'] = 200;

But with the previous example you don't have the advantage of the checks in the initialize method.

It's powerful stuff if you use it right.
