Re: return NULL by reference

Well I can't reliably reproduce it, is this expected behavior or not? If there is a cleaner solution I'd like to try that first. I'd like to turn off this error altogether even if I have to patch and recompile. I can't see anything like this in the changelogs. Since when should anything not be allowed to return null? -Jeff ----- Original Message ----- From: "Daniel Convissor" <danielc@analysisandsolutions.com> To: "Jeffrey Moss" <jeff@opendbms.com> Cc: <internals@lists.php.net> Sent: Monday, September 27, 2004 12:04 PM Subject: Re: [PHP-DEV] return NULL by reference > On Mon, Sep 27, 2004 at 11:52:24AM -0600, Jeffrey Moss wrote: > > > return NULL; > ... snip ... > > "Only variable references should be returned by reference " > > Just like the error message says.
