如何修復已被錯誤字節計數長度損壞的序列化字符串？我使用的是Hotaru CMS和圖像上傳插件，如果我試圖將圖像附加到一個帖子中，我會得到這個錯誤，否則沒有錯誤：取消序列化()[功能.非序列化]：在偏移量處出錯違規代碼(錯誤點指向*)：/**
* Retrieve 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($submitted_data); } else { return false; }**
}
}數據從表，注意結束位有圖像信息，我不是一個PHP專家，所以我想知道你們這些家伙/女孩可能會怎么想？temdata_value：a:10:{s:16:"submit_editorial";b:0;s:15:"submit_orig_url";s:13:"www.bbc.co.uk";s:12:"submit_title";s:14:"No title found";s:14:"submit_
content";s:12:"dnfsdkfjdfdf";s:15:"submit_category";i:2;s:11:"submit_tags";s:3:"bbc";s:9:"submit_id";b:0;s:16:"submit_subscribe";i:0;s:15
:"submit_comments";s:4:"open";s:5:"image";s:19:"C:fakepath100.jpg";}編輯：我想我找到了序列化的部分./**
* Save submission step data
*
* @return bool
*/
public function saveSubmitData($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 " . TABLE_TEMPDATA . " (tempdata_key, tempdata_value, tempdata_updateby) VALUES (%s,%s, %d)";
$h->db->query($h->db->prepare($sql, $key, serialize($h->vars['submitted_data']), $h->currentUser->id));
return $key;
}

$fixed_data = preg_replace_callback ( '!s:(\d+):"(.*?)";!', function($match) {
return ($match[1] == strlen($match[2])) ? $match[0] : 's:' . strlen($match[2]) . ':"' . $match[2] . '";';},$bad_data );
