php - 反序列化报错，后台数据变成疑似乱码？

Question

用serialize()序列化数据后插入数据库，再用unserialize()反序列化出来的时候遇到了部分数据字符串报错；
报错内容为：unserialize() [function.unserialize]: Error at offset 0 of 2544 bytes

谷歌搜了好多解决方法都是说用 是由于编码的问题导致的
于是在插入的地方改为 base64_encode(serialize($str));
读取的地方改为
unserialize(preg_replace('!s:(d+):"(.*?)";!se', '"s:".strlen("$2").":"$2";"', $string))

我就试了是有效但没有完全解决，后来还是出现部分数据报同样错误，查看后台数据可发现插入的内容变成了下图的类似乱码的东西

求各路大神帮忙看看什么原因，最好能详细点。

Answer 1

Post some source data, otherwise how can you test it? .

Answer 2

Confirm whether there is any problem with your serialized data. I used serialize before, but it always had problems. Then I had no choice but to change to json_decode

Answer 3

base64_encode("a:1") == "YTox".

That data is base64 encoded, not garbled.

Answer 4

unserialize(base64_decode($str))
