我们常用做商城时会希望把用户输入的数字转换在RMB大写形式了,下面我整理了几个可以处理万亿级的数字转换例子,大家一起来看看这些例子吧。

<script>ec(2);</script>

例子1

 代码如下 复制代码

function change_num($num)
 {
 $d = array('零','壹','贰','叁','肆','伍','陆','柒','捌','玖');
 $e = array('元','拾','佰','仟','万','拾万','佰万','仟万','亿','拾亿','佰亿','仟亿','万亿');
 $p = array('分','角');
 $zheng='整'; //追加"整"字
 $final = array(); //结果
 $inwan=0; //是否有万
 $inyi=0; //是否有亿
 $len_pointdigit=0; //小数点后长度
 $y=0;
 if($c = strpos($num, '.')) //有小数点,$c为小数点前有几位数
 {
 $len_pointdigit = strlen($num)-strpos($num, '.')-1; // 判断小数点后有几位数
 if($c>13) //简单的错误处理
 {
 echo "数额太大,已经超出万亿.";
 die();
 }
 elseif($len_pointdigit>2) //$len_pointdigit小数点后有几位
 {
 echo "小数点后只支持2位.";
 die();
 }
 }
 else //无小数点
 {
 $c = strlen($num);
 $zheng = '整';
 }
 for($i=0;$i  {
 $bit_num = substr($num, $i, 1); //逐字读取 左->右
 if($bit_num!=0 || substr($num, $i+1, 1)!=0) //当前是零 下一位还是零的话 就不显示
 @$low2chinses = $low2chinses.$d[$bit_num];
 if($bit_num || $i==$c-1)
 @$low2chinses = $low2chinses.$e[$c-$i-1];
 }
 for($j=$len_pointdigit; $j>=1; $j--) //处理小数部分
 {
 $point_num = substr($num, strlen($num)-$j, 1); //逐字读取 左->右
 if($point_num != 0)
 @$low2chinses = $low2chinses.$d[$point_num].$p[$j-1];
 //if(substr($num, strlen($num)-2, 1)==0 && substr($num, strlen($num)-1, 1)==0) //小数点后两位都是0
 }
 $chinses = str_split($low2chinses,2); //字符串转换成数组
 //print_r($chinses);
 for($x=sizeof($chinses)-1;$x>=0;$x--) //过滤无效的信息
 {
 if($inwan==0&&$chinses[$x]==$e[4]) //过滤重复的"万"
 {
 $final[$y++] = $chinses[$x];
 $inwan=1;
 }
 if($inyi==0&&$chinses[$x]==$e[8]) //过滤重复的"亿"
 {
 $final[$y++] = $chinses[$x];
 $inyi=1;
 $inwan=0;
 }
 if($chinses[$x]!=$e[4]&&$chinses[$x]!=$e[8]) //进行整理,将最后的值赋予$final数组
 $final[$y++] = $chinses[$x];
 }
 $newstring=(array_reverse($final)); //$final为倒数组,$newstring为正常可以使用的数组
 $nstring=join($newstring); //数组变成字符串
 if(substr($num,-2,1)==0 && substr($num,-1)0) //判断原金额角位为0 ? 分位不为0 ?
 {
 $nstring=substr($nstring,0,(strlen($nstring)-4))."零".substr($nstring,-4,4); //这样加一个零字
 }
 $fen="分";
 $fj=substr_count($nstring, $fen); //如果没有查到分这个字
 return $nstring=($fj==0)?$nstring.$zheng:$nstring; //就将"整"加到后面
 }


例子2

 1.支持天文数字,整数位理论上可以无限的长;
    2.支持小数,对于货币,一般精确到小数后两位,可以设置小数位是否四舍五入;
    3.支持自定义货币单位,有的系统要求大写是"圆",有的要求是"元",可以自定义;
    4.支持整数以0结束并含有小数的数字自定义末尾补"零",比如有的系统要求1960.30这样的数字转大写之后是"壹仟玖佰陆拾元叁角",而有的系统则要求"壹仟玖佰陆拾元零叁角",这两种情况按"正确填写票据和结算凭证的基本规定"都是正确的,现在可已自定义。

     * @param bool $is_extra_zero 是否对整数部分以0结尾,小数存在的数字附加0,比如1960.30,
     *             有的系统要求输出"壹仟玖佰陆拾元零叁角",实际上"壹仟玖佰陆拾元叁角"也是对的
