Php 把数字转换成单词

下面的PHP代码将数字转换为文字。对于像5250这样的整数，这很好，但是，当给定一个带小数的数字时，它无法正确解析该数字

450将输出“450”。然而，450.5将输出“四千五百”，应该是四百五十点五

我在网上搜索过，但我找不到解决办法。有人能建议改正吗

<?php
    function inr($number){
        //A function to convert numbers into words.
        $words = array(
        '0'=> '' ,'1'=> 'one' ,'2'=> 'two' ,'3' => 'three','4' => 'four','5' => 'five',

    }

问题中的代码没有将数字拆分为小数点；它只查看字符串中的所有数字。所以，它当然不起作用。要使其正常工作，请执行以下操作：

• 使用上述程序处理小数点之前的零件
• 如果有小数点：
  • 添加“点”
  • 例如，在小数点后每位数加一个单词，使

    .45

    变为

    第四点和第五点

这里有一个可行的解决方案。它可能不完全适用于您正在尝试做的事情，但它应该是一个良好的开端。关键是通过一个递归调用重用您的工作。如果对小数点后的数字再次调用函数，则可以合并结果：

function inr($number, $doOtherWords = true){
    //A function to convert numbers into words.
    $words = array(
    '0'=> '' ,'1'=> 'one' ,'2'=> 'two' ,'3' => 'three','4' => 'four','5' => 'five',
    '6' => 'six','7' => 'seven','8' => 'eight','9' => 'nine','10' => 'ten',
    '11' => 'eleven','12' => 'twelve','13' => 'thirteen','14' => 'fouteen','15' => 'fifteen',
    '16' => 'sixteen','17' => 'seventeen','18' => 'eighteen','19' => 'nineteen','20' => 'twenty',
    '30' => 'thirty','40' => 'fourty','50' => 'fifty','60' => 'sixty','70' => 'seventy',
    '80' => 'eighty','90' => 'ninty');

    //First find the length of the number
    $number_length = strlen($number);
    //Initialize an empty array
    $number_array = array(0,0,0,0,0,0,0,0,0);        
    $received_number_array = array();

    // Save off if we have a decimal in a variable. Assume we don't
    $hasDecimal = false;
    $numberAfterDecimal = '';
    //Store all received numbers into an array
    //ONLY do this until we find a decimal
    for($i=0;$i<$number_length;$i++) { 
        $character = substr($number,$i,1);    
        if ($character == '.') {
            $hasDecimal = true;
            $numberAfterDecimal = substr($number, $i+1);
            $received_number_array[$i] = 0;
        } elseif ($hasDecimal) {
            $received_number_array[$i] = 0;
        } else {
            $received_number_array[$i] = $character;
        }
    }


    //Populate the empty array with the numbers received - most critical operation
    for($i=9-$number_length,$j=0;$i<9;$i++,$j++){ $number_array[$i] = $received_number_array[$j]; }
    $number_to_words_string = "";        
    //Finding out whether it is teen ? and then multiplying by 10, example 17 is seventeen, so if 1 is preceeded with 7 multiply 1 by 10 and add 7 to it.
    for($i=0,$j=1;$i<9;$i++,$j++){
        if($i==0 || $i==2 || $i==4 || $i==7){
            if($number_array[$i]=="1"){
                $number_array[$j] = 10+$number_array[$j];
                $number_array[$i] = 0;
            }        
        }
    }
    $value = "";
    for($i=0;$i<9;$i++){
        if($i==0 || $i==2 || $i==4 || $i==7){
            $value = $number_array[$i]*10; 
        } else{ 
            $value = $number_array[$i];
        }            

        if($value!=0){ 
            $number_to_words_string.= $words["$value"]." "; 
        }

        if ($doOtherWords) {
            if($i==1 && $value!=0){    $number_to_words_string.= "Crores "; }
            if($i==3 && $value!=0){    $number_to_words_string.= "Lakhs ";    }
            if($i==5 && $value!=0){    $number_to_words_string.= "Thousand "; }
            if($i==6 && $value!=0){    $number_to_words_string.= "Hundred "; }
        }
    }

    // At this point you have the solution for everything BEFORE the decimal
    // Now handle the decimal through recursion if in fact we have one
    if ($hasDecimal) {
        $number_to_words_string .= 'point ' . inr($numberAfterDecimal, false);
    }
    if($number_length>9){ $number_to_words_string = "Sorry This does not support more than 99 Crores"; }
    if ($doOtherWords) {
        return ucwords(strtolower("Rupees ".$number_to_words_string)."Only.");
    }
    // Don't add the other words on the recursive call
    return ucwords(strtolower($number_to_words_string));
}

$my_fig=inr(450.56);
echo $my_fig;

函数inr（$number，$doOtherWords=true）{
//将数字转换为文字的函数。
$words=数组(
“0”=>“，“1”=>“1”、“2”=>“2”、“3”=>“3”、“4”=>“4”、“5”=>“5”，
‘6’=>‘6’、‘7’=>‘7’、‘8’=>‘8’、‘9’=>‘9’、‘10’=>‘10’，
‘11’=>‘11’、‘12’=>‘12’、‘13’=>‘13’、‘14’=>‘fouteen’、‘15’=>‘十五’，
‘16’=>‘16’、‘17’=>‘17’、‘18’=>‘18’、‘19’=>‘19’、‘20’=>‘20’，
‘30’=>‘30’、‘40’=>‘40’、‘50’=>‘50’、‘60’=>‘60’、‘70’=>‘70’，
‘80’=>‘80’、‘90’=>‘90’）；
//首先找出数字的长度
$number_length=strlen（$number）；
//初始化空数组
$number_array=数组（0,0,0,0,0,0,0,0）；
$received_number_array=array（）；
//如果变量中有小数点，请保存。假设没有小数点
$hasDecimal=false；
$numberFrafterDecimal=''；
//将所有接收到的数字存储到一个数组中
//只在找到小数点之前执行此操作
对于（$i=0；$i首先确定整数和小数点后的数字，请使用
$number=explode（“.”，$number）；
将两个数字分隔为一个数组

$number[0]将是您的整数，$number[1]将是小数点后的数字

function inr($number[0]){
/* Your function for the whole number */
}

function inr2($number[1]){
/* Your function for the number after the decimal point */
}

可能重复的
