扫描后解析出来是乱码
urlencode后是如下内容
%C2%B0%C3%99%C2%B6%C3%88%C2%B0%C3%99%C2%BF%C3%86%C2%A3%C2%AD%C2%B6%C3%BE%C3%8E%C2%AC%C3%82%C3%AB%C2%B4%C3%8A%C3%8C%C3%B5
我用微信扫描解析却是可以的
内容是"百度百科-二维码词条"
这是经过了什么编码处理过么?怎么才能得到真正的结果?

使用这个解析器也是

$s = '%C2%B0%C3%99%C2%B6%C3%88%C2%B0%C3%99%C2%BF%C3%86%C2%A3%C2%AD%C2%B6%C3%BE%C3%8E%C2%AC%C3%82%C3%AB%C2%B4%C3%8A%C3%8C%C3%B5';$s = urldecode($s);echo utf8_decode($s);
Copy after login
百度百科-二维码词条

解得的串是 gbk 编码的

大神现身立马解决问题了,
现在还有一个疑问,请问我应该如何判断什么时候应该用utf8_decode呢

这样判断能看明白吗

$s = '%C2%B0%C3%99%C2%B6%C3%88%C2%B0%C3%99%C2%BF%C3%86%C2%A3%C2%AD%C2%B6%C3%BE%C3%8E%C2%AC%C3%82%C3%AB%C2%B4%C3%8A%C3%8C%C3%B5';$s = urldecode($s);if(mb_check_encoding('utf-8')) {  $n = 0;  for($i=0; $i<strlen($s); $i+=2) if((ord($s{$i}) & 0xf0) == 192) $n++;  if($n > strlen($s)/2 * 0.8) $s = utf8_decode($s);}echo $s;
Copy after login

其实直接统计原串中 %C 的个数也是一样的

我刚才自己尝试的用mb_detect_encoding(utf8_decode('阿萨德asda'))=='ASCII' 这样来判断需要用
不知道这样精确不
