Can't unserialize objects?

I took an object, and saved it into a database serialized.

 

$object_here = serialize($theobject);

Then later on, I go and I get that data from a database, and try to unserialize it..

 

$objecthere = unserialize($row->theobject)

 

And it throws the following error...any advice?

Warning: unserialize() [function.unserialize]: Node no longer exists in /path/to/file on line 20

1.) Make sure that the database field is large enough to hold the serialized array. Serialized data is very space-inefficient in PHP, and many DBs (like MySQL) will silently truncate field values that are too long.

 

2.) Make sure that you are not serializing a resource id / object (because they can't be serialized)

 

3.) When saving serialized data, don't try and do anything to it other than escaping ( mysql_real_escape_string() )

I am taking an XML feed, and turning it into an array with

 

$response = simplexml_load_string($results);

 

Then I am turning the $response->actions which is an object, into a serialized string.  Then saving it into a database table, as a varchar 225...

it's not a large array though.
