You could use eval, something like this:
$num = count($params);
$vars = '$subject = new foo2(';
if($num > 0) {
$i = 0;
foreach($params as $var){
$vars .= ($i > 0)? ',':'';
$vars .= (is_string($var))? "'".$var."'" : $var;
$i ++;
}
}
$vars .= ');';
eval($vars);
untested but is similar to something I use as a class loader with
unknown number of variables to pass.
