Here is a cutdown version of a class loader I use, It works for php4 and
php5 and with references. It should be easy to modify.

<?php
function &load_class($class_name,$arg1,$arg2,$arg3){
  $num_args = func_num_args();
  $arg_list = func_get_args();
  
  $vars = '$return =& new '.$class_name.'(';
  if($num_args > 1) {
    for ($i = 1; $i < $num_args; $i++) {
      $vars .= ($i > 1)? ',':'';
      $varname = 'variable'.$i;
      $$varname =& $arg_list[$i];
      $vars .= "\$$varname";
    }
  }
  $vars .= ');';
  eval($vars);
  return $return;
}
?>
