PHP - Create a Multidimensional Array Using Dynamic Function Arguments

I need a function like this one:

function multi(){
    $args = get_func_args();
    $array = ????
    return $array;
}
print_r(multi('foo','bar','baz',123));
// expected result: array([foo] => array([bar] => array([baz] => 123)))

---

I've answered multiple variations of this using a reference to build-up the array:

function multi() {
    $path = func_get_args();      //get args
    $value = array_pop($path);    //get last arg for value

    $result = array();            //define our result
    $temp = &$result;             //reference our result

    //loop through args to create key
    foreach($path as $key) {
        //assign array as reference to and create new inner array
        $temp =& $temp[$key];
    }
    $temp = $value;               //set the value

    return $result;
}

print_r(multi('foo','bar','baz',123));
