unserialize() [function.unserialize]: Error at offset是invalid serialization data由于长度无效引起的
您可以做的是recalculating the length序列化数组中的元素
$data = 'a:10:{s:16:"submit_editorial";b:0;s:15:"submit_orig_url";s:13:"www.bbc.co.uk";s:12:"submit_title";s:14:"No title found";s:14:"submit_content";s:12:"dnfsdkfjdfdf";s:15:"submit_category";i:2;s:11:"submit_tags";s:3:"bbc";s:9:"submit_id";b:0;s:16:"submit_subscribe";i:0;s:15:"submit_comments";s:4:"open";s:5:"image";s:19:"C:fakepath100.jpg";}';
var_dump(unserialize($data));
输出量
Notice: unserialize() [function.unserialize]: Error at offset 337 of 338 bytes
$data = preg_replace('!s:(\d+):"(.*?)";!e', "'s:'.strlen('$2').':\"$2\";'", $data);
var_dump(unserialize($data));
输出量
array
'submit_editorial' => boolean false
'submit_orig_url' => string 'www.bbc.co.uk' (length=13)
'submit_title' => string 'No title found' (length=14)
'submit_content' => string 'dnfsdkfjdfdf' (length=12)
'submit_category' => int 2
'submit_tags' => string 'bbc' (length=3)
'submit_id' => boolean false
'submit_subscribe' => int 0
'submit_comments' => string 'open' (length=4)
'image' => string 'C:fakepath100.jpg' (length=17)

您如何序列化数据
您如何保存它..
由于使用双引号"而不是单引号而产生了错误'，因此将C:\fakepath\100.png其转换为C:fakepath100.jpg
您需要更改$h->vars['submitted_data']发件人（请特别注意'）
更换
$h->vars['submitted_data']['image'] = "C:\fakepath\100.png" ;
用
$h->vars['submitted_data']['image'] = 'C:\fakepath\100.png' ;
function satitize(&$value, $key)
{
$value = addslashes($value);
}
array_walk($h->vars['submitted_data'], "satitize");
如果您具有UTF字符，也可以运行
$h->vars['submitted_data'] = array_map("utf8_encode",$h->vars['submitted_data']);
findSerializeError ( $data1 ) ;
输出量
Diffrence 9 != 7
-> ORD number 57 != 55
-> Line Number = 315
-> Section Data1 = pen";s:5:"image";s:19:"C:fakepath100.jpg
-> Section Data2 = pen";s:5:"image";s:17:"C:fakepath100.jpg
