Buy me a beer The Weekly Book Project php unserialize error at offset 0 About me Testimonials Contact @jackreichert Musings Reference Web Development Design Handling a PHP unserialize undefined offset error in php offset error… and why it happens I discovered recently the importance of proper collation of database tables. 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 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 error at offset 0 of 1 bytes 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 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 f

3457 bytes I looked around and couldn’t find a simple a solution. I’m notice: unserialize(): error at offset drupal sure this error can occur in other ways, but I was trying with the simplest of arrays: Array("Ryan" notice unserialize() error at offset opencart => "Bosinger"); My problem was that my echo statement was throwing some whitespace in there. That’s all. This fixed it: $data["search_results"] = file_get_contents("http://localhost/sphider/search.php?query=" . $search_for . "&search=1&start=" . $start); $result_string = https://www.jackreichert.com/2014/02/handling-a-php-unserialize-offset-error/ trim($data["search_results"]); $result_array = unserialize($result_string); Basically, try trimming the whitespace before unserializing. Hope that helps! Also, I was using Codeigniter but I really don’t think that has anything to do with it. Creating your first programming language is easier than you think.

Some stackoverflow article says it would return false, but in my case I ended up with the same error as you. Only a try/catch kept my app from throwing an error… Reply Plamen Tetevensky says: October 22, 2014 at 1:03 pm Your output buffer already contains some leading data (zeros, \r, \n, etc.) from outside your opening php tag.

Two schools of thought on how best to have Drupal react are discussed examining the error at benefits of each to either the novice user and/or the experienced developer. It appears a consensus has been reached that most examples of breakage are the result of older contributed modules not being properly (cleanly) uninstalled which can result in old variables remaining in the database or database table structure and then, upon new update/upgrade, being unrecognized which leads the upgrade/update to hard failure. You error at offset get an error likeNotice: unserialize() [function.unserialize]: Error at offset X of Y bytes in variable_initialize() (line 916 of .../includes/bootstrap.inc By clicking 'Clear all caches' on admin/config/development/performance the error comes back again. Proposed resolution Create a softer failure method for Drupal. Drupal should identify and communicate with the user that the update/upgrade process has failed, providing meaningful feedback not only on the source and nature of the failure, but providing adequate direction on resolving the failure. Iterate over all variables and check each for their consistency. (borrowed from variablecheck module.) Allow for a hotfix through settings.php $conf Throw an exception when encountered inconsistent variable(s). Steps to reproduce drush sql-query "update variable set value='unserialized value' where name='site_name'" drush cc all Visit the site. Exception is thrown. Now hotfix by editing settings.php and uncomment the line with $conf['site_name']. Now site_name is valid again. Visit the site again. Workaround Easy route: install http://drupal.org/project/variablecheck as mentioned in #10 There is some variable from the variables table misformed. Check your database by running the following SQL. Make sure to replace the Y with the real value. SELECT name, length(value), value FROM variable where length(value) < Y - 5 and

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");
