it only takes a minute: 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. The offending code (error points to line with **): /** * Retrieve offset 0 outside of image source submission step data * * @param $key - empty when setting * @return bool */ public function loadSubmitData($h, $key = '') { // delete everything in this table older than 30 minutes: $this->deleteTempData($h->db); if (!$key) { return false; } $cleanKey = preg_replace('/[^a-z0-9]+/','',$key); if (strcmp($key,$cleanKey) != 0) { return false; } else { $sql = "SELECT tempdata_value FROM " . TABLE_TEMPDATA . " WHERE tempdata_key = %s ORDER BY tempdata_updatedts DESC LIMIT 1"; $submitted_data = $h->db->get_var($h->db->prepare($sql, $key)); **if ($submitted_data) { return unserialize($submitted_data); } else { return false; }** } } Data from the table, notice the end bit has the image info, I am not an expert in PHP so I was wondering what you guys/gals might think? tempdata_value: a:10:{s:16:"submit_editorial";b:0;s:15:"submit_orig_url";s:13:"www.bbc.co.uk";s:12:"submit_title";s:14:"No title found";s:14:"submit_content";s:12:"dnfsdkfjdfdf";s:15:"submit_category";i:2;s:11:"submit_tags";s:3:"bbc";s:9:"submit_id";b:0;s:16:"submit_subscribe";i:0;s:15:"submit_comments";s:4:"open";s:5:"image";s:19:"C:fakepath100.jpg";} Edit: I think I've found the serialize bit... /** * Save submission step data * * @return bool */ public function saveSubmitData($h) { // delete everything in this table older than 30 minutes: $this->deleteTempData($h->db); $sid = preg_replace('/[^a-z0-9]+/i', '', session_id()); $key = md5(microtime() . $sid . rand()); $sql = "INSERT INTO " .

Making updates to these forms would be very costly since it would take quite a bit of time to add and remove DB error at offset fields as well as update the HTML form. I'd like to revert the information into an array format just like it came in easily. For that reason, I've been using the serialize() and unserialize() functions often. Serializing an array keeps the information in an array format, so to speak, but in one long string. Anyways, I ran into the following error when testing unserialize on some information that I had serialized: Notice: unserialize(): Error at offset 2 of 52 bytes in file.php on line 130 It turns out that if there's a ", ', :, or ; in any of the array values the serialization gets corrupted. I've found the following fix for this issue on PHP.net: //to safely serialize $safe_string_to_store = base64_encode(serialize($multidimensional_array)); //to unserialize... $array_restored_from_db = unserialize(base64_decode($encoded_serialized_string)); It's a great fix to simple problem!

Symfony member stof commented Dec 7, 2012 If you want a backtrace, run the console with the --verbose option gergelypolonkai commented Dec 8, 2012 It's the same: $ app/console cache:clear --verbose [ErrorException] Notice: unserialize(): Error at offset 97 of 99 bytes in /var/www/html/vendor/symfony/symfony/src/Symfony/Component/Config/Resource/FileResource.php line 78 gergelypolonkai commented Dec 8, 2012 If I remove the cache directory, and run cache:clear again (or cache:warmup), everything goes back to normal. gergelypolonkai commented Dec 13, 2012 I have added a debug line to FileResource.php, so I could generate a backtrace. Here it is: https://gist.github.com/4275576 Actually, it tries to unserialize this string: s:91:"/var/www/html/platea/app/cache/dev/jms_diextra/doctrine/EntityManager_50c9a1736b0f8.php";}i:4 which is clearly invalid at the given position. ghost-x47 commented Dec 14, 2012 I get the same error, but it's only if i cache:clear with debug . If i provide --no-debug to cache:clear - error disappearing. Oh, and seems like cache:warmup is working too. Also i have no clue how did i get it, it just suddenly showed up. gergelypolonkai commented Dec 16, 2012 I have successfully captured an HTML version of the exception. It's 127kB and contains the whole backtrace. Where can I upload it? Elendev commented Dec 18, 2012 Hello, same bug here and I've also successfully captured an HTML version of the exception.
