The global variable isnt being assigned the mysql connection resource id. This worked fine with PHP3 and 4.

* Ive noticed that using anything like:
    $$varname = "GOODBYE";
... assigns correctly, only with mysql_connect() the assignment is ignored.

* If you remove the global declaration and use:
    $GLOBALS[$varname] = mysql_connect();
.. it works.

Reproduce code:
  function checkme($varname = 'var') {
    global $$varname;

    $$varname = mysql_connect("your", "data", "here");

  $var = 'HELLO';
  echo $var; // Should be a resource_id, but its "HELLO" 

Expected result:
Resource Id #<something>

Actual result:
