下面这段代码放在 公共function里面

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; 
    }

下面这段代码放在控制器里面

 public 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); 
    }

 直接调用即可  echo cny('12300');
