Description:
------------
Builds an associative array using value of previous defined vars.
It works on PHP 4.0.10
It doens't work on PHP 5.0.3

If the var names don't have "_" (underscore) in the name it works on PHP4 AND PHP5.

Reproduce code:
---------------
function do_array() {
  $new_array=array(); 
  foreach (func_get_args() as $var) {     
  if (isset($GLOBALS[$var]))
    $new_array[$var]=$GLOBALS[$var];
  else exit("<b>Error</b>: var '<b>$var</b>' is not set.");
  } 
  return $new_array;
} 
$domain_name = "php.net";
$visit_date = date("Y-m-d");
$array = do_array("domain_name", "visit_date");

Expected result:
----------------
$array = ("domain_name" => "php.net",
          "visit_date" => "2005-02-14"
);

Actual result:
--------------
Error: var 'domain_name' is not set.
