Passing Variable Length Argument List to Parent

[Mark]

hello!

I have a class method that takes a variable number of parameters and
correctly deals with them with func_get_args, etc ...

i.e.

class ABC
{
public function MooSaysTheCow()
{
foreach (func_get_args( ) as $arg_name => $arg_value)
{
...
}
}
}

now, the problem is: i want to override this class and this method, have
that overriding method call the base class and then do something else. The
problem is that I don't know how to pass the parameters along.

class DEF
{
public function MooSaysTheCow()
{
parent::MooSays TheCow( WHAT DO I PUT HERE ????? );
echo "Overridden version with new exciting features!";
}
}
Any ideas?

the best i've thought of so far is terribly yucky, and not flexible to
arbitrary numbers of parameters .... blech.

class DEF
{
public function MooSaysTheCow()
{
switch (func_get_num_a rgs())
{
case 1:
parent::MooSays TheCow(func_get _arg(0));
break;
case 2:
parent::MooSays TheCow(func_get _arg(0), func_get_arg(1) );
break;
etc ....
...
..

nope. probably would have in PHP4, but most certainly not in PHP5.
Hmm. The following works here on PHP5 when called statically:

class TBar {
function doSomething() {
print_r(func_ge t_args());
}
}

class TFoo extends TBar {
function doSomething() {
$args = func_get_args() ;
call_user_func_ array(array('pa rent', 'doSomething'), $args);
}
}

TFoo::doSomethi ng(23, 42);

If called on an instance of TFoo my PHP crashes. But if I declare the
above methods 'static' then it works, even if invoked non-statically ...
i'm still stuck with the switch statement in PHP5, unfortunately.

You could also try it with eval(), as already mentioned in another post.
