php怎么实现数字转化成大写？

php将金额数字转化为中文大写

echo toChineseNumber(1234567890);//壹拾贰亿叁仟肆佰伍拾陆万柒仟捌佰玖拾圆
function toChineseNumber($money){
  $money = round($money,2);
  $cnynums = array("零","壹","贰","叁","肆","伍","陆","柒","捌","玖"); 
  $cnyunits = array("圆","角","分");
  $cnygrees = array("拾","佰","仟","万","拾","佰","仟","亿"); 
  list($int,$dec) = explode(".",$money,2);
  $dec = array_filter(array($dec[1],$dec[0])); 
  $ret = array_merge($dec,array(implode("",cnyMapUnit(str_split($int),$cnygrees)),"")); 
  $ret = implode("",array_reverse(cnyMapUnit($ret,$cnyunits))); 
  return str_replace(array_keys($cnynums),$cnynums,$ret); 
}
function cnyMapUnit($list,$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; 
 }

代码二：

/**

*String Int $num 要转换的小写数字或小写字符串
*return 大写字母
*小数位为两位
