couldn't you loop through the $classarray and unset each $key => $value 
of the array?

foreach ( $class as $key => $value ) {
 unset($class[$key])
}

that should fully obliterate reference to the class.  i think

I think you should bring this up on the [email protected] . In the past I had also the same reasons for it (dynamic remote code updating with PHP-GTK, etc.) but this won't be implemented just because of a few feature requests.

I think the main problem is that "making it work" far exceeds the benefits over the time it takes to implement so we'll just have to forget it (imho).

Suspending.

ok, i got answers like this a thousand times.

i am using php to write a console script. it should be able to dynamically load "modules" like DLLs under windows. These modules are, of course, coded in php and contain classes.

the first time when such a module is executed by "eval" all classes in it are defined in class namespace, everything is fine.

now i want to unload the module - who would i undefine it's class?
even if i didn't use classes - functions can't be undefined, either.

any other suggestions of how to implement a "DLL" like system? the only solution i can think of was encapsulating a general module in an class, instanciating it for every module i load, and call it's functions by the objects interface. but this will disable me from directly calling methods in my module...

i know this sounds weird, but php is such a flexible language, it should be able to load functions/objects dynamically!! this would be great.

uhm? this sounds like a VERY bad idea to me... and very clumsy programming.
