如何修复已被错误的字节数长度损坏的序列化字符串？

unserialize() [function.unserialize]: Error at offset是invalid serialization data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:\fakepath\100.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:\fakepath\100.png" ; 用

$h->vars['submitted_data']['image'] = 'C:\fakepath\100.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

$h->vars['submitted_data'] = array_map("utf8_encode",$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 "

"; $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

$toDatabse = base64_encode(serialize($data)); // Save to database $fromDatabase = unserialize(base64_decode($data)); //Getting Save Format 分享来源：stack overflow
