我提供一个我经收藏的PHP的一个的币制大小写转换程序
  

  

  function cny($ns) {
  

  static $cnums=array("零","壹","贰","叁","肆","伍","陆","柒","捌","玖"),
  

  $cnyunits=array("圆","角","分"),
  

  $grees=array("拾","佰","仟","万","拾","佰","仟","亿");
  

  list($ns1,$ns2)=explode(".",$ns,2);
  

  $ns2=array_filter(array($ns2[1],$ns2[0]));
  

  $ret=array_merge($ns2,array(implode("", _cny_map_unit(str_split($ns1), $grees)), ""));
  

  $ret=implode("",array_reverse(_cny_map_unit($ret,$cnyunits)));
  

  return str_replace(array_keys($cnums), $cnums,$ret);
  

  }
  

  function _cny_map_unit($list,$units) {
  

  $ul=count($units);
  

  $xs=array();
  

  foreach (array_reverse($list) as $x) {
  

  $l=count($xs);
  

  if ($x!="0" || !($l%4)) $n=($x=='0'?'':$x).($units[($l-1)%$ul]);
  

  else $n=is_numeric($xs[0][0]) ? $x : '';
  

  array_unshift($xs, $n);
  

  }
  

  return $xs;
  

  }
