How to re-generate Node Object from database stored Serialized Node Data .. and then Save as New Node?
Now how can i transform these data back into Drupal $node Object please?


As said you can use the following code,

$node = unserialize($data);





  Then how can i node_save($node) (as new node) upon them? (What tricks will i need?)


You can null the nid, vid and use node_save to save it as a new node like this:

$node-&gt;nid = NULL;
$node-&gt;vid = NULL;
node_save($node);
