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.

You do realise, array_combine() does exactly that, right? Not to mention that even were you using php4 there are several user comments throughought php.net that show you how to accomplish this very thing (And if I recall, There's a PEAR_COMPAT package that contains this functionality.)
