• mb_decode_numericentity()根据 HTML 数字字符串解码成字符

To get Unicode numbers out of a UTF-8 string, this can be used, for example: 

To improve handling of EURO-Symbols in dan at boxuk dot com's function add the following line to $convmap:
128,128,0, $f,

Here is a better explanation of convmap:

We were experiencing difficulties with PHP/Sablotron on Solaris; placing HTML character references into the XSL transformation, when set to output UTF-8, converts them back into UTF8 encoded chars. This was then a problem for non unicode storage. Using a bit of code from http://homepage.mac.com/marko/ the following function converts the string back to character references:
function utf2html ($utf2html_string)
{
  $f = 0xffff;
  $convmap = array(
/* 
  %HTMLlat1; */
   160, 255, 0, $f,
/* 
  %HTMLsymbol; */
