i suggest the passthru functionality to pass parameter to other method
without typing all parameters,like call_user_func_array.

foo(passthru()); = call_user_func_array('foo', `func_get_args()`);


// case 1:

function a($a,$b,$c)
{
//...
}

function aa()
{
a(passthru()); // like call_user_func_array('a', `func_get_args()`);
someOthers();
}

aa('foo','bar','baz');



//case 2:

class base
{
protected function insert(BaseType $object,$a,$b,$c)
{
 }
}

class son extends base
{
public function insert(SonType $object) //type hinting differs from base
{
parent::insert(passthru()); // like call_user_func_array(array('parent',
'insert'), `func_get_args()`);
}
}

$son = new son();
$sonType = new SonType();
$son->insert($sonType,'foo','bar','baz');

We already have function with this name: http://us.php.net/passthru

example.

i'm suggesting new feature, the name can be decided later

php test source:

<?php
echo "TEST 1\n";
function a($a,$b,$c)
{
  echo "$a $b $c\n";
}

function aa()
{
  call_user_func_array('a',func_get_args());// a(pervade();
}

aa(1,2,3);

echo "TEST 2\n";

class BaseType{}
class SonType extends BaseType{}

class base
{
  protected function insert(BaseType $o,$a,$b,$c)
  {
    print_r(func_get_args());
  }
}

class son extends base
{
  public function insert(SonType $o)
  {
    call_user_func_array(array('parent','insert'),func_get_args()); //
parent::insert(pervade());
  }
}

$son = new son();
$son->insert(new SonType(),1,2,3);


php test result:
TEST 1
1 2 3
TEST 2
Array
(
    [0] => SonType Object
        (
        )

    [1] => 1
    [2] => 2
    [3] => 3
)

Two things:
a) There is a way of doing it and although it is a bit cryptic I find it
appropriate since I don't consider this something which should be done
in regular code.
b) pervade() could not be a normal function but would have to be a
special language construct as far as I can see as the compiler needs to
know to call a() with multiple arguments. Not desirable IMHO.

If you want to have multiple dynamic arguments to pass on like this I'd
suggest you use one associative array as parameter instead.

Like
	function a($p = array()) { ... }
	function aa($p = array()) { a($p); }
	aa(array("foo" => 42, "bar" => 17));
with the additional benefit of having named (and extensible) parameters
as an added bonus.

array cant be type hinting defined. i will need to do some extra work
checking type in the reciever function.
