definition of transcoding

This article brings to you the content is about PHP emoji transcoding display implementation code, there is a certain reference value, the need for a friend can refer to, I hope you have some help. Preg_match_all ('/\[\[emoji: (. *?) \]\]/', $data [' content '], $arr _content);//filter out emoji expression foreach ($arr _content[0] as $k = = $v) { $emoji = Str2emoji ($v ); $data [' content '] = Str_replace ($v, $emoji, $data [' content

This article provides a detailed analysis of PHP's automatic judgment of character sets and transcoding. For more information, see the principle. because gb2312/gbk is a two-byte Chinese character, these two bytes have a value range, while the Chinese character in UTF-8 is three bytes, and each byte also has a value range. The English language only occupies one byte (excluding the full width), regardless of the encoding ). For file encoding checks, yo

This article provides a detailed analysis of Chinese character transcoding using php. For more information, see the following: The code is as follows: Function unicode_encode ($ str, $ encoding = 'gbk', $ prefix = ' #', $ postfix = ';'){$ Str = iconv ($ encoding, 'ucs-2', $ str );$ Arrstr = str_split ($ str, 2 );$ Unistr = '';For ($ I = 0, $ len = count ($ arrstr); $ I {$ Dec = hexdec (bin2hex ($ arrstr [$ I]);$ Unistr. = $ prefix. $ dec. $ po

Why do I need to transcode?Four scenarios where the client sends a request to the server: 1, direct access to the URL method; 2, the page link (belongs to get request); 3. Form get Submit ; 4. Form Post Submission1.url (URL and page link): Each big browser, each operating system of the URL Uri, querystring encoding may be different .

php5.4 before the Json_encode when the Chinese will be Unicode encoding, Chinese will be encoded, become unreadable, similar to the "\u***" format, but also to a certain extent, increase the amount of data transferred. For example: Copy CodeThe code is as follows: $str = ' Chinese '; echo Json_encode ($STR); "\u4e2d\u6587" php5.4 start Echo Json_encode ($str, Json_unescaped_unicode); Chinese php5.4 let JSON know more Chinese! no Unicode transcoding
