How to use

//$a = new Num2RmbClass;
echo (Num2RmbClass::num2rmb('1600020039.9989','圆',false,false,false));

Let me share with you a simpler one

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; 
}

$value='23058.04';
print cny($value);echo'
';

输出：贰万叁仟零伍拾捌圆肆角
