PHP function with unlimited number of parameters

Question

How do I write a function that can accept unlimited number of parameters?

What am trying to do is create a function within a class that wraps the following:

$stmt->bind_param('sssd', $code, $language, $official, $percent);

Have you taken a look at func_get_args, func_get_arg and func_num_args

So for example:

function foo(){
    if ( func_num_args() > 0 ){
        var_dump(func_get_args());
    }
}

or:

function bind_param(){
    if ( func_num_args() <= 1 ){
        return false; //not enough args
    }
    $format = func_get_arg(0)
    $args = array_slice(func_get_args(), 1)

    //etc
}

EDIT
Regarding Ewan Todds comment:
I don't have any knowlege of the base API you are creating the wrapper for, but another alternative may be to do something with chaining functions so your resulting interface looks something like:

$var->bind()->bindString($code)
            ->bindString($language)
            ->bindString($official)
            ->bindDecimal($percent);

Which I would prefer over the use of func_get_args as the code is probably more readable and more importantly less likely to cause errors due to the the lack of a format variable.
