PHP：使用字增加計數器功能（即第一，第二，第三等）

Question

我一直在試圖找到一個函數使用單詞增加計數器。我知道它可能使用帶後綴的數字（即1st，2nd，3rd等）。下面是代碼片段我有：

function addOrdinalNumberSuffix($num) { 
    if (!in_array(($num % 100),array(11,12,13))){ 
     switch ($num % 10) { 
      // Handle 1st, 2nd, 3rd 
      case 1: return $num.'st'; 
      case 2: return $num.'nd'; 
      case 3: return $num.'rd'; 
     } 
    } 
    return $num.'th'; 
} 

Code Source

但是，有沒有辦法用言語來複制這個（即第一，第二，第三，等等）？我希望創建一個無限計數器是相當困難的（但不是不可能的），但是任何高達20的計數器就足夠了。

任何幫助將不勝感激。

Answer 1

有一個class從PEAR包可以做到這一點：

<?php 

// include class 
include("Numbers/Words.php"); 

// create object 
$nw = new Numbers_Words(); 

// convert to string 
echo "600 in words is " . $nw->toWords(600); 

?>

Answer 2

二十是沒有太多硬編碼。你只需要一個數組，而不是一個函數。

$array = array('First', 'Second', 'Third', ...); 

foreach ($array as $key => $value) 
{ 
    echo "$value index is $key"; 
} 

更直接的答案是：沒有一個內置的功能，做你在找什麼。

Answer 3

這裏去一些僞代碼，在希望好辦法也許導致：

input = //any number 
output = string (input) 
if output ends with '1' then output += 'st' 
else if output ends with '2' then output += 'nd' 
else if output ends with '3' then output += 'rd' 
else output += 'th' 

Answer 4

序數（僅英文）的基礎上，SIFE的回答是：

include("Numbers/Words.php"); 

function Nth($n) 
{ 
    $nw = new Numbers_Words(); 
    $s = $nw->toWords($n); 
    $replacements = array(
     'one' => 'first', 
     'two' => 'second', 
     'three' => 'third', 
     've' => 'fth', 
     't' => 'th', 
     'e' => 'th', 
     'y' => 'ieth', 
     '' => 'th', 
    ); 
    foreach ($replacements as $from => $to) 
    { 
     $count = 0; 
     $r = preg_replace('/' . $from . '$/', $to, $s, 1, $count); 
     if ($count) 
      return $r; 
    } 
} 

Answer 5

下面是一個簡單的PHP鏈接功能，顯示瞭如何以簡單的方式處理這個問題： http://webdeveloperblog.tiredmachine.com/php-converting-an-integer-123-to-ordinal-word-firstsecondthird/

所提供的示例僅適用到五十年代，但可以很容易地在擴展噸o達到更高的範圍。

function numToOrdinalWord($num) 
{ 
    $first_word = array('eth','First','Second','Third','Fouth','Fifth','Sixth','Seventh','Eighth','Ninth','Tenth','Elevents','Twelfth','Thirteenth','Fourteenth','Fifteenth','Sixteenth','Seventeenth','Eighteenth','Nineteenth','Twentieth'); 
    $second_word =array('','','Twenty','Thirthy','Forty','Fifty'); 

    if($num <= 20) 
     return $first_word[$num]; 

    $first_num = substr($num,-1,1); 
    $second_num = substr($num,-2,1); 

    return $string = str_replace('y-eth','ieth',$second_word[$second_num].'-'.$first_word[$first_num]); 
}
