Euhm. vsprintf()? Takes an array, loves it actually.

Well, the best I can do to achieve what I think you want:
Call an arbitrary function with an arbitrary amount of arguments, switching
scalars and arrays like it doesn't care, the first argument given is the
function, be it in a scalar or the first scalar in the first array (of the
first array and so forth):
<?php
function flatten_array($arg){
if(!is_array($arg)) return array($arg);
$return = array();
foreach($arg as $row){
if(is_array($row));
$return = array_merge($return,flatten_array($row));
} else {
$return[] = $row;
}
}
return $return;
}
function varargsfunction(){
$array = func_get_args();
$array = flatten_array($array);
$function = array_shift($array);
return call_user_func_array($function,$array);
}
?>
