发个PHP人民币金额数字转中文大写

人民币金额数字转中文大写，无聊也用php写了一段相同功能的代码：

php代码 
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; 
}
