Sign up unserialize() [function.unserialize]: Error at offset up vote 47 down vote favorite 33 I am using Hotaru CMS with the Image Upload plugin, I get this error if I try to attach an image to a post, otherwise there is no error.

Drupal Notice: Unserialize(): Error At Offset
July 24, 2009.Edited by debrajn, xtfer, larowlan, tobiasb. Log in to edit this page.Improperly Serialized Variables in Database When loading a notice unserialize() error at offset opencart page the following error occurs when loading an improperly serialized array from the variables table. The same technique can be used for bad serialized data in other tables. Error PHP Notice: unserialize() [function.unserialize]: http://stackoverflow.com/questions/10152904/unserialize-function-unserialize-error-at-offset Error at offset 6 of 10 bytes in \includes\bootstrap.inc on line 428 Depending on how caching is set on your site, you may only see this error sometimes. Because once the variables are cached they may not be loaded every time. Some Causes of Serialization Issues Changing serialized content via sql replace command such as when migrating a site. You can't do this unless you follow up and put the https://www.drupal.org/node/529866 length of the new value in by hand. Serializing resources Serializing objects and unserializing them without the class code loaded Serialized string is truncated because it is too long for the field it is stored in. Encoding/Decoding PHP/mysql issues Incorrect installation/compilation/configuration of APC (php extension) Debugging Technique Around line 550 of bootstrap.inc in drupal 6 change the code to as follows. (Set aside the old code to replace afterward) This will show you the variables that are throwing errrors. The @ symbol before unserialize suppresses the error so all the variables can be checked before code execution stops. // if ($cached = cache_get('variables', 'cache')) { // $variables = $cached->data; // } // else { $result = db_query('SELECT * FROM {variable}'); while ($variable = db_fetch_object($result)) { $variables[$variable->name] = @unserialize($variable->value); if ($variables[$variable->name] === FALSE) { print "
Unserialize Error for variable:". $variable->name . '='. $variables[$variable->name] . "
". $variable->value; } } die; cache_set('variables', $variables); // } You may only get the error when variables are first loaded. After that they may be cached. So to reproduce the error, flush the cache via sql: truncate table cache_block; truncate table cache; truncate table cache_content; truncate table cache_filter; truncate table cache_form; truncate table cache_menu; truncate table cache_views; Resolution If you are getting

I inherited a proprietary CMS to manage. The default http://board.phpbuilder.com/showthread.php?10358820-RESOLVED-Unserialize-Problem-Error-at-offset-0-of-4-bytes collation was latin1_swedish_ci. Apparently it's because "The bloke who wrote it was co-head of a Swedish company". The problem occurred when a form we had on our site began getting submissions with foreign characters. The database collation error at couldn't accept the characters and was saving them as question marks (?). "Serialization is the process of translating data structures or object state into a format that can be stored." For example the array: $returnValue = serialize(array('hello', 'world')); Will become: a:2:{i:0;s:5:"hello";i:1;s:5:"world";} This is what the above string means: There is an array that is 2 in length. a:2. The first item in the array has a key that is an integer with the error at offset value of 0. i:0. The value for that item is a string that is 5 characters long, which is "hello". s:5. The second item in the array has a key that is an integer with the value of 1. i:1. The value for that item is a string that is 5 characters long, which is "world". s:5. An unserialize offset error can occur when the string count in the serialized data does not match the length of the string being saved. so in the above example that would look like this: a:2:{i:0;s:4:"hello";i:1;s:5:"world";} Notice the number ‘4', while there are really 5 characters in the world ‘hello'. So the question is, why would the offset happen when a ? replaces a foreign character? To understand why, you need to dig into how UTF-8 works and things will become clear. The UTF-8 value of ‘?' is ‘3f', while the value for ‘Æ' is ‘c3 86'. '?' translates into s:1:"?"; while 'Æ' translates into s:2:"Æ";. Notice the 2 replacing the 1 in the string length. So basically, what's happening is that when php serializes the data it is storing the foreign character as a double the length but when it's passed to MySQL, when the table isn't formatted for UTF-8, the database converts the character to a ?, which is then stored as a single character. But the serialization length

The object is first stored serialized into a session variable, unserialized and displayed in a form, re-serialized and sent via session to another form, where it is put, serialized, into a hidden control that form. Then it is sent by POST to this script, which stores, then gets, the object from an sql database. Here is where it is stored into the DB. (The ObjectString is coming from a hidden control on another page, it is the serialized string of the object) PHP Code: $conn=newmysqli("localhost","root","----","test");
$query="INSERTINTOobject(Object)VALUES('{$_POST['ObjectString']}')"
