我目前正在为从doc文件生成的html文件编写解析器。字符串包含像alpha beta等符号…问题是，当我做一个urldecode(urlencode(alpha));时，它没有给出符号…它返回别的东西
要找到我的问题，请查看
urldecode("%0A%20%20If%20%3Ci%20style%3D%22mso-bidi-font-style%3Anormal%22%3E%CE%B1%3C%2Fi%3E%2C%20b%2C%20g%0A%20%20be%20the%20zeroes%20of%20the%20polynomial%20%3Ci%20style%3D%22mso-bidi-font-style%3Anormal%22%3Eax%3C%2Fi%3E%3Csup%3E3%3C%2Fsup%3E%0A%20%20%2B%20b%3Ci%20style%3D%22mso-bidi-font-style%3Anormal%22%3Ex%3C%2Fi%3E%3Csup%3E2%3C%2Fsup%3E%20%2B%20c%3Ci%20style%3D%22mso-bidi-font-style%3Anormal%22%3Ex%3C%2Fi%3E%20%2B%20d%2C%20the%20the%20value%20of%20%3Ci%20style%3D%22mso-bidi-font-style%3Anormal%22%3E%26nbsp%3B%CE%B1%3C%2Fi%3Eb%20%2B%20bg%20%2B%20g%3Ci%20style%3D%22mso-bidi-font-style%3Anormal%22%3E%20%CE%B1%3C%2Fi%3E%26nbsp%3B%20is%0A%20%20");
有办法解决这个问题吗?
您的字符集不匹配。该符号可能被解码为UTF-8，但您将该站点解释为其他内容，例如Latin-1。要确认这一点，请从浏览器的View> Encoding菜单中选择UTF-8。设置一个适当的标题，使网站总是使用UTF-8:
header('Content-Type: text/html; charset=utf-8');
这意味着您还需要确保您的网站的其余部分是有效的UTF-8，否则匹配您的文本的编码。
You can used javascript function unescape($urlfordecode);
Its decode your url, if you want to mannually check then used following url
$urlfordecode ="Your encoded url place here";
$a = explode('&', $urlfordecode);
$i = 0;
while ($i < count($a)) {
$b = explode('=', $a[$i]);
echo 'Your decoded url is => </br>',htmlspecialchars(urldecode($b[0])),
htmlspecialchars(@urldecode($b[1])), "<br />'n";
$i++;
}
