nasty code - varaiable variables varaible paramaters

[eluser]xwero[/eluser]
Where is the overhead?

Code:

function one($one,$two,$three)
{
   return $one.' '.$two.' '.$three;
}
// vs
function one($array)
{
   return $array[0].' '.$array[1].' '.$array[2];
}

The only overhead i can think of is doing following

Code:

function one($array)
{
    list($one,$two,$three) = $array;
    return $one.' '.$two.' '.$three;
}

So it's only one line to create meaningful variables.

There is no func_set_args or something similar i know of. If you are going to support n parameters i think you will have no other option?
