PHP：使用单词（例如，First，Second，Third等）的增量计数器功能。

| 我一直在尝试找到一个使用单词递增计数器的函数。我知道可以使用带后缀的数字（即1st，2nd，3rd等）。这是我的代码片段： 
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\';
}
代码源 但是有没有办法用单词（即第一，第二，第三等）来复制呢？ 我希望创建一个无限计数器非常困难（但并非不可能），但是最多20个就足够了。 任何帮助将非常感激。

    PEAR包中有一个类可以做到： 
    <?php

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

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

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

?>

    硬编码不需要二十。您只需要一个数组，而不是一个函数。 
    $array = array(\'First\', \'Second\', \'Third\', ...);

foreach ($array as $key => $value)
{
  echo \"$value index is $key\";
}
    更为直接的答案是：没有内置功能可以满足您的需求。

    这里有一些伪代码可能以一种希望的好方法进行了引导： 
    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\'

    普通票（仅英语），基于SIFE的答案： 
    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;

    这是一个简单的PHP函数的链接，该函数显示了如何以一种简单的方式处理此问题： http://webdeveloperblog.tiredmachine.com/php-converting-an-integer-123-to-ordinal-word-firstsecondthird/ 提供的示例仅适用于五十年代，但可以轻松扩展到更高的范围。 
    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]);
}
