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

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
Questions about the output after character transcoding
Header ("content-type:text/plain;charset=gb2312");
Header ("Content-disposition:attachment;filename=". Date ("Ymdhis"). " Test.xls ");
echo iconv ("UTF8", "gb2312", "Weibo id\t");
Why is there no data in the exported Excel table?
If you rewrite the UTF8 in the Iconv function to Utf-8, there is no problem.
Please explain why, thank you.
------Solution--------------------
UTF8 is UTF8 encode
When iconv encounters a character that cannot be transcoded, the interrupted content is lost. the code is as follows: $ c amp; lsquo; test amp; bull; character transfer amp; bull; Happy May Day! Amp; rsquo; echoiconv ( amp; lsquo; UTF-8 amp; prim
Iconv is interrupted when transcoding fails. the code is as follows:
$ C = 'Test • character transfer • Happy May Day! ';
Echo iconv ('utf-8', 'gbk', $ c );
Only output: After the test,
