note 63701 added to function.session-set-save-handler

With regards to the read handler, the docs say: "Read function must return string value always to make save handler work as expected. Return empty string if there is no data to read." I can't emphasize this enough. I just spent half a day trying to figure out why my sessions weren't storing any information. I was blithely returning the results of a query on the database from the read handler. Since there was no match for the new ID, the result was NULL. Since it wasn't a string, sessions were essentially disabled. So, the safe thing might be something like this: <?php function sessRead($id) { // Look up data $results = getStuff($id); // Make sure it's a string settype($results, 'string'); return $results; } ?> Of course, you can do whatever you want with it. But, no matter what, make sure you return a string.
