can $this be passed as a method parameter?

[lkrubner@geocities.com]

In a class, can $this be passed by reference or value?

function setDatabaseObje ct("MySql", $this) {
// some code here checks the name of the
// class of the object that is calling this method
}

For security, and to enforce naming conventions, I'd like for some of
my objects to only be callable from certain classes, but the only way
I can think for an object to get the name of the calling code is if I
had in the $this keyword.

in php5 you would mean something like this?

function foo($caller, $bar)
{
// do something with the reflection api i can find in the manual?
}

$class = new Class;
foo($class, "fubar");

A situation for debug_backtrace (). Just keep stepping back until you find a
class name that's permitted.
