Calling parent function with call_user_func_array

I'm a self-confessed PHP newb (first step towards a cure, right?), so
apologies in advance for what may be a basic question. I spent an hour
searching for an answer to this and couldn't find one.

I found one post that said there was a problem with this in 5.0.3, but
it didn't indicate whether the fix was also applied to the PHP4 branch.

I'm using PHP v4.4.7. I have class B which extends class A. I'm
overriding a function that is normally called with a variable number of
parameters via call_user_func_array. How do I call the class A
implementation of the function using call_user_func_array from the class
B implementation?

class A {
function doSomething($elements, $level) {
...
}
}

Class B extends A {
function doSomething($elements, $level) {
...
call_user_func_array(/*class A implementation of doSomething*/,
args);
}
}

Thanks in advance for any help!
