UrlEncode: Refers to the URL of the Web page in the Chinese characters of an encoding conversion, the most common is Baidu, Google and other search engines in the input of English Query time, generated through the Encode page URL. UrlEncode generally have two ways, one is the traditional GB2312-based encode (Baidu, Yisou, etc.), the other is based on UTF-8 (Google, Yahoo and other uses).
This tool implements encode and decode in two ways, respectively:
Encode,%D6%D0%CE%C4, GB2312, Chinese
Encode,%e4%b8%ad%e6%96%87, UTF-8, Chinese
UrlEncode in HTML:
HTML file encoded as GB2312: http://s.jb51.net/. RAR---browser automatically converted to Http://s.jb51.net/%D6%D0%CE%C4.rar
Note: Firefox is not good for the Chinese URL of GB2312 encode because it defaults to UTF-8 encoding send URL, but ftp://protocol can, I tried, I think this should be a Firefox bug.
HTML file encoded as UTF-8: http://s.jb51.net/. RAR---browser automatically converted to Http://s.jb51.net/%E4%B8%AD%E6%96%87.rar
UrlEncode in PHP:
Copy CodeThe code is as follows:
<?php
GB2312 's Encode
Echo UrlEncode ("Chinese-_."). " \ n "; %d6%d0%ce%c4-_.+
Echo UrlDecode ("%d6%d0%ce%c4-_."). " \ n "; Chinese-_.
Echo Rawurlencode ("Chinese-_."). " \ n "; %d6%d0%ce%c4-_.%20
Echo Rawurldecode ("%d6%d0%ce%c4-_."). " \ n "; Chinese-_.
?>
Except for "-_." All non-alphanumeric characters will be replaced with a percent percent "%" followed by a two-digit hexadecimal number.
The difference between UrlEncode and Rawurlencode: UrlEncode encodes a space as a plus "+", and Rawurlencode encodes a space as a plus "%20".
If you want to use UTF-8 's encode, there are two ways:
One, save the file as UTF-8 file, directly use UrlEncode, Rawurlencode can.
Second, use the Mb_convert_encoding function:
Copy CodeThe code is as follows:
<?php
$url = ' http://s.jb51.net/Chinese. rar ';
Echo UrlEncode (mb_convert_encoding ($url, ' utf-8 ', ' gb2312 ')). " \ n ";
Echo Rawurlencode (mb_convert_encoding ($url, ' utf-8 ', ' gb2312 ')). " \ n ";
Http%3a%2f%2fs.jb51.net%2f%e4%b8%ad%e6%96%87.rar
?>
Instance:
Copy CodeThe code is as follows:
<?php
function parseURL ($url = "")
{
$url = Rawurlencode (mb_convert_encoding ($url, ' gb2312 ', ' utf-8 '));
$a = Array ("%3a", "%2f", "%40");
$b = Array (":", "/", "@");
$url = Str_replace ($a, $b, $url);
return $url;
}
$url = "Ftp://ud03:[email protected]/Chinese/English. rar";
echo parseURL ($url);
Ftp://ud03:[email Protected]/%d6%d0%ce%c4/%d6%d0%ce%c4.rar
?>
UrlEncode in javascript:
such as:%e4%b8%ad%e6%96%87-_.%20%e4%b8%ad%e6%96%87-_.%20
encodeURI does not encode the following characters: ":", "/", ";", "?", "@" and other special characters.
such as: Http://s.jb51.net/%E4%B8%AD%E6%96%87.rarhttp%3A%2F%2Fs.jb51.net%2F%E4%B8%AD%E6%96%87.rar
