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

Notes:
* 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:
---------------
<?php
  function checkme($varname = 'var') {
    global $$varname;

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

  $var = 'HELLO';
  checkme();
  echo $var; // Should be a resource_id, but its "HELLO" 
?>


Expected result:
----------------
Resource Id #<something>


Actual result:
--------------
HELLO
