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 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=24421&edit=1
