note 19563 added to function.session-set-save-handler

I just want to mention, that it's critical to return a string value with the read function, because there can be strange errors if - for example - the return value is null. In my case the php program stopped in the middle of an "echo" command, so it was really hard to find, that the real problem was with that session read callback function. The easyest way to handle this, that you should cast the return value before return. For example: function read ($id) { /* code here to produce $retval */ return (string)$retval; } -- http://www.php.net/manual/en/function.session-set-save-handler.php http://master.php.net/manage/user-notes.php?action=edit+19563 http://master.php.net/manage/user-notes.php?action=delete+19563 http://master.php.net/manage/user-notes.php?action=reject+19563
