Lately I got this error in my script while trying to decode serialized UTF-8 string:

unserialize() [function.unserialize]: Error at offset 118 of 512

Here’s a simple solution I found. Instead of using unserialize() you should use mb_unserialize():

function mb_unserialize($str)
{
    $res = preg_replace('!s:(\d+):"(.*?)";!se', "'s:'.strlen('$2').':\"$2\";'", $str );
    return unserialize($res);
}

You can also think about replacing in your program serialize() + unserialize() with json_encode() + json_decode(). Your data should be safer then.
