今天在做公司的项目的时候，遇到一个问题，群聊天记录存入数据库的时候把聊天记录及央视使用16进制转换，我在做将聊天记录导出为text文本的时候，需要将聊天记录先从16进制转换为普通的Unicode编码记录

然后在从中取出所需要导出的message信息，不多说了，代码如下，以下代码属于线下的，线上的就不透漏了，算是一篇非常的简单的php教程吧：

代码如下

复制代码

/*将16进制编码转换为汉字*/
function hexDecode($s) {
return preg_replace('/(w{2})/e',"chr(hexdec('\1'))",$s);
}
/*汉字转换成16进制后的编码*/
$str="7B22636F6E74726F6C223A22343AE5AE8BE4
BD932C422C302C30222C22657874656E6469

222C226D7367223A2261
646720227D"; www.111cn.net
$a=hexDecode($str);//调用反转换函数转换16进制
echo $a;//输出{"control":"4:宋体,B,0,0","extendinfo":"20140327185359|0|~不要打酱油~","extendtype":"","type":"normalmsg","msg":"adg "}
$a = json_decode($a);
echo($a->msg);//取出msg字段信息
?>

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
