当我们在写支付账单的时候需要填写数字金额的大写，说真的平时没写还真写不出来，为了以后不出现尴尬的场面，还特意去练了那十个字。哈哈，当然，我们在php中也可以转换的，于是有了下面这个转换函数：
/**
* 金额的小写转大写
* @param $ns int 输入的数字
*/
function cny($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, $cnyunitss)));
return str_replace(array_keys($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;
}
