unserialize() [function.unserialize]: Error at offset是
invalid serializationdata由于长度无效引起的
快速解决
您可以做的是
recalculating the length序列化数组中的元素
您当前的序列化数据
$data = 'a:10:{s:16:"submit_editorial";b:0;s:15:"submit_orig_url";s:13:"www.bbc.co.uk";s:12:"submit_title";s:14:"No title found";s:14:"submit_content";s:12:"dnfsdkfjdfdf";s:15:"submit_category";i:2;s:11:"submit_tags";s:3:"bbc";s:9:"submit_id";b:0;s:16:"submit_subscribe";i:0;s:15:"submit_comments";s:4:"open";s:5:"image";s:19:"C:fakepath100.jpg";}';无需重新计算的示例
var_dump(unserialize($data));
输出量
Notice: unserialize() [function.unserialize]: Error at offset 337 of 338 bytes
重新计算
$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)
推荐 ..我
而不是使用这种快速修复方法…我会建议您使用
您如何序列化数据
您如何保存它..
===============================编辑1 ================ ===============
错误
由于使用双引号
"而不是单引号而产生了错误
'，因此将
C:fakepath100.png其转换为
C:fakepath100.jpg
解决错误
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:fakepath100.png" ;
用
$h->vars['submitted_data']['image'] = 'C:fakepath100.png' ;
附加过滤器
您还可以在调用序列化之前添加此简单过滤器
function satitize(&$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
$h->vars['submitted_data'] = array_map("utf8_enpre",$h->vars['submitted_data']);如何在将来的序列化数据中检测问题
findSerializeError ( $data1 ) ;
输出量
Diffrence 9 != 7 -> ORD number 57 != 55 -> Line Number = 315 -> Section Data1 = pen";s:5:"image";s:19:"C:fakepath100.jpg -> Section Data2 = pen";s:5:"image";s:17:"C:fakepath100.jpg^------- The Error (Element Length)
findSerializeError功能
function findSerializeError($data1) { echo "<pre>"; $data2 = preg_replace ( '!s:(d+):"(.*?)";!e', "'s:'.strlen('$2').':"$2";'",$data1 ); $max = (strlen ( $data1 ) > strlen ( $data2 )) ? strlen ( $data1 ) : strlen ( $data2 ); echo $data1 . PHP_EOL; echo $data2 . PHP_EOL; for($i = 0; $i < $max; $i ++) { if (@$data1 {$i} !== @$data2 {$i}) { echo "Diffrence ", @$data1 {$i}, " != ", @$data2 {$i}, PHP_EOL; echo "t-> ORD number ", ord ( @$data1 {$i} ), " != ", ord ( @$data2 {$i} ), PHP_EOL; echo "t-> Line Number = $i" . PHP_EOL; $start = ($i - 20); $start = ($start < 0) ? 0 : $start; $length = 40; $point = $max - $i; if ($point < 20) { $rlength = 1; $rpoint = - $point; } else { $rpoint = $length - 20; $rlength = 1; } echo "t-> Section Data1 = ", substr_replace ( substr ( $data1, $start, $length ), "<b style="color:green">{$data1 {$i}}</b>", $rpoint, $rlength ), PHP_EOL; echo "t-> Section Data2 = ", substr_replace ( substr ( $data2, $start, $length ), "<b style="color:red">{$data2 {$i}}</b>", $rpoint, $rlength ), PHP_EOL; } }}保存到数据库的更好方法
$toDatabse = base64_enpre(serialize($data)); // Save to database$fromDatabase = unserialize(base64_depre($data)); //Getting Save Format
