Howto re-pass arguments?

Hello :-)

Is it possible to pass all arguments to another function?

function A()
{
B(func_get_args());
}

function B()
{
var_dump(func_get_args());
}


I dont know how many arguments will come for A, and i want
A to handle them transparent and pass all to B.
Now i'm doing this with func_get_args but I get
an array ob B's input. original arguments would be
better. Is this possible in any way?

TIA 8-)

function b($array) {
if(is_array($array)) {
foreach($array AS $var) {
var_dump($var);
}
} else {
var_dump($array);
}
}

No no no ;-) My fault, see this:

//
function A()
{
B(); // THIS NEEDS TO BE CHANGED PROBLY :>
}

//
function B()
{
var_dump(func_get_args());
}


So, I will NEVER call B directly, i'll always call A
an A will call B for me.

B is loaded/generated dynamicaly, so one time B requires
2 arguments, sometimes 5 arguments. As i said i will
only call A, sometimes A($var1,$var2,$var3), other
A($var1). How can I tell A to pass all its
arguments to B - WITHOUT having them as an array (as result
of fun_get_args in my previous posting).

I hope this is clear now ;-) sorry for my english

If you want the arguments that are used when you call function A(), you need
to use func_get_args() in function A(), so you would need to use
b(func_get_args()). As you see from b(), it won't present your variables
inside a array.

Ok, thanks :-) Array is not bad, but I thought I could
do this in a more "transparent" way, without "touching"
the arguments.

Yes: http://de2.php.net/call_user_func_array.

function A()
{
$tmp = func_get_args();
return call_user_func_array( 'B', $tmp );
}

function B() { /* do something */ }

BTW, you cannot pass func_get_args() directly as a parameter to
call_user_func_array(), as PHP will get confused and report an error.
Therefore, it is necessary to go via the $tmp variable.
