將數字轉換爲其字符串表示形式

Question

我正在開發一個簡單的Web應用程序，其中需要以字符串格式向我的用戶顯示數字a。

實施例：

12 - One Two or Twelve 
-20 - minus Two zero or minus twenty 

無論哪種方式是好的。我需要這樣做在PHP中完成。任何幫助將不勝感激。

Answer 1

的第一個選項（拼出位），strtr是你的朋友

$words = array(
    '-' => 'minus ', 
    '1' => 'one ', 
    '2' => 'two ', 
etc.... 
); 

echo strtr(-123, $words); 

Answer 2

如果你想拼出完整的號碼，你可以使用PEARNumbers_Words class。該類有一個toWords（）方法，該方法接受+ve或-ve num並返回拼出的字符串表示形式的數字。

如果你想將數字轉換爲字符串數字明智的，我不知道任何lib函數。但是你可以輕鬆編寫自己的代碼。 user187291 gives a good way to do this in his answer。

<?php 

$arr = array(
     -12, 
     20 
      ); 

foreach($arr as $num) { 
     $nw = new Numbers_Words(); 
    echo "$num = ". $nw->toWords($num)."\n"; 
}  

?> 

輸出：

C:\>php a.php 
-12 = minus twelve 
20 = twenty

波紋管我給你舉個例子功能。它可能不是一個完整的，但它應該讓你開始（我知道，這個問題已經發布很久了，但它可以幫助其他人 - ） 我對任何錯誤:)感到抱歉。最後，它還沒有完成。我只是以一個例子爲出發點。對@SRC在前面的回答所做的工作

function convertToString($number, $blankIfZero=true){ 
     $strRep = ""; 
     $n = intval($number);  
     $one2twenty = array("One", "Two", "Three", "Four", 
       "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Eleven", 
       "Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen", 
       "Seventeen", "Eighteen", "Nineteen"); 
     $twenty2ninty = array("Twenty", "Thirty", 
       "Fourty", "Fifty", "Sixty", "Seventy", "Eighty", 
       "Ninety"); 
     $hundred = "Hundred"; 
     $thousand = "Thousand"; 
     $million = "Million"; 
     $billion = "Billion"; 

     switch($n){ 
      case 0: 
       if($blankIfZero == true){ 
        $strRep= $strRep.""; 
        break; 
       }else{ 
        $strRep = $strRep."Zero"; 
        break; 
       } 
      case $n >0 && $n <20: 
       $strRep = $strRep." ".$one2twenty[($n-1)];    
       break; 
      case $n >=20 && $n < 100:    
       $strRep = $strRep . " ". $twenty2ninty[(($n/10) - 2)]; 
       $strRep .= convertToString($n%10); 
       break; 
      case $n >= 100 && $n <= 999: 
       $strRep = $strRep.$one2twenty[(($n/100)-1)]." ".$hundred. " "; 
       $strRep .= convertToString($n%100); 
       break; 
      case $n >= 1000 && $n < 100000: 
       if($n < 20000){ 
        $strRep = $strRep.$one2twenty[(($n/1000)-1)]." ".$thousand. " "; 
        $strRep .= convertToString($n%1000); 
        break; 
       }else{ 
        $strRep = $strRep . $twenty2ninty[(($n/10000) - 2)]; 
        $strRep .= convertToString($n%10000); 
        break; 
       } 
      case $n >= 100000 && $n < 1000000: 
       $strRep .= convertToString($n/1000). " ".$thousand. " "; 
       $strRep .= convertToString(($n%100000)%1000); 
       break; 
      case $n >= 1000000 && $n < 10000000:     
       $strRep = $strRep . $one2twenty[(($n/1000000) - 1)]. " ".$million." "; 
       $strRep .= convertToString($n%1000000); 
        break; 
      case $n >= 10000000 && $n < 10000000000: 
       $strRep .= convertToString($n/1000000). " ".$million. " "; 
       $strRep .= convertToString(($n%1000000)); 
       break; 

     } 

     return $strRep; 
    }

大廈，我寫了一個函數任意裸無符號整數轉換成英語，主要是出於好奇。

您可以在這裏找到的代碼：a GitHub Gist by StampyCode（64位）

這個代碼僅由PHP的整數限制的限制：

9223372036854775807 

它是此代碼處理，輸出：

九個百分點，二百二十三萬億，三百二十二萬億，三十六十億，八百四十萬，七百七十五萬，ei GHT百零七

代碼中嵌入：
