Notice Unserialize() Error At Offset Opencart
I inherited a proprietary CMS to manage. The default 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 couldn't accept the characters and was saving them as question marks (?). "Serialization is the process of magento notice unserialize() error at offset 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 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 t

Log in to edit this laravel unserialize(): error at offset page.Improperly Serialized Variables in Database When loading a page the following error occurs when loading an improperly serialized array from the variables table. The same technique can be used for bad serialized https://www.jackreichert.com/2014/02/handling-a-php-unserialize-offset-error/ data in other tables. Error PHP Notice: unserialize() [function.unserialize]: 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 https://www.drupal.org/node/529866 as when migrating a site. You can't do this unless you follow up and put the 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 "
