php阿拉伯数字金额转中文大写金额
1、public static function num_to_rmb($num) {
$c1 = "零壹贰叁肆伍陆柒捌玖";
$c2 = "分角元拾佰仟万拾佰仟亿";
//精确到分后面就不要了，所以只留两个小数位
$num = round($num, 2);
//将数字转化为整数
$num = $num * 100;
if (strlen($num) > 10) {
return "金额太大，请检查";
}
$i = 0;
$c = "";
while (1) {
if ($i == 0) {
//获取最后一位数字
$n = substr($num, strlen($num) - 1, 1);
} else {
$n = $num % 10;
} //每次将最后一位数字转化为中文
$p1 = substr($c1, 3 * $n, 3);
$p2 = substr($c2, 3 * $i, 3);
if ($n != '0' || ($n == '0' && ($p2 == '亿' || $p2 == '万' || $p2 == '元'))) {
$c = $p1 . $p2 . $c;
} else {
$c = $p1 . $c;
}
$i = $i + 1;
//去掉数字最后一位了
$num = $num / 10;
$num = (int) $num;
//结束循环
if ($num == 0) {
break;
}
}
$j = 0;
$slen = strlen($c);
while ($j < $slen) {
//utf8一个汉字相当3个字符
$m = substr($c, $j, 6);
//处理数字中很多0的情况,每次循环去掉一个汉字“零”
if ($m == '零元' || $m == '零万' || $m == '零亿' || $m == '零零') {
$left = substr($c, 0, $j);
$right = substr($c, $j + 3);
$c = $left . $right;
$j = $j - 3;
$slen = $slen - 3;
}
$j = $j + 3;
}
//这个是为了去掉类似23.0中最后一个“零”字
if (substr($c, strlen($c) - 3, 3) == '零') {
$c = substr($c, 0, strlen($c) - 3);
}
//将处理的汉字加上“整”if (empty($c)) {
return "零元整";
} else {
return $c . "整";
}
}
该方法转换后返回效果如下所示
2、首先定义需要转换金额的中文金额字符
$c1 = "零壹贰叁肆伍陆柒捌玖";
$c2 = "分角元拾佰仟万拾佰仟亿";
定义如图所示
3、然后判断金额准确性
//精确到分后面就不要了，所以只留两个小数位
$num = round($num, 2);
//将数字转化为整数
$num = $num * 100;
if (strlen($num) > 10) {
return "金额太大，请检查";
}
4、然后定义判断条件并循环取出，并依次转换为中文字符
$i = 0;
$c = "";
while (1) {
if ($i == 0) {
//获取最后一位数字
$n = substr($num, strlen($num) - 1, 1);
} else {
$n = $num % 10;
}
//每次将最后一位数字转化为中文
$p1 = substr($c1, 3 * $n, 3);
$p2 = substr($c2, 3 * $i, 3);
if ($n != '0' || ($n == '0' && ($p2 == '亿' || $p2 == '万' || $p2 == '元'))) {
$c = $p1 . $p2 . $c;
} else {
$c = $p1 . $c;
} $i = $i + 1;
//去掉数字最后一位了
$num = $num / 10;
$num = (int) $num;
//结束循环
if ($num == 0) {
break;
}
}
5、定义判断条件，将转换的中文字符计算长度作为判断循环
$j = 0;
$slen = strlen($c);
while ($j < $slen) {
//utf8一个汉字相当3个字符
$m = substr($c, $j, 6);
//处理数字中很多0的情况,每次循环去掉一个汉字“零”
if ($m == '零元' || $m == '零万' || $m == '零亿' || $m == '零零') {
$left = substr($c, 0, $j);
$right = substr($c, $j + 3);
$c = $left . $right;
$j = $j - 3;
$slen = $slen - 3;
}
$j = $j + 3;
}
6、最后处理不必要字符，并返回完整中文字符
if (substr($c, strlen($c) - 3, 3) == '零') {
$c = substr($c, 0, strlen($c) - 3);
}
//将处理的汉字加上“整”
if (empty($c)) {
return "零元整";
} else {
return $c . "整";
}
