I have a question about using $this as an argument in a method.
As I understand it, the only issue here is if you are passing $this from constructor of your class from PHP 4. In short, when you do
$var = new MyClass();
you are actually storing a copy of what constructor was seeing as $this, and if you passed $this from constructor to an outside function that stores it somewhere, then you now have two different objects. Way to circumvent this is to use
$var = & new MyClass();
ie, use a reference, or make sure that your script will be running on PHP5. If you do the above thing with reference in PHP 5 though, you will get a warning that this is deprecated.
Hope this helps...
Boban.
