在PHP中将单词转换为数字

Question

我正在尝试将以单词形式编写的数值转换为整数。例如，“ iPhone有233.7万个应用程序”将变成“ iPhone为230783个应用程序”在开始编码之前，我想知道此转换是否存在任何功能/代码。

Answer 1

我还没有对它进行过广泛的测试，直到我看到输出中所期望的东西时，我才或多或少地对其进行了研究，但是它似乎可行，并且从左到右进行了解析。

<?php

$str = 'twelve billion people know iPhone has two hundred and thirty thousand, seven hundred and eighty-three apps as well as over one million units sold';

function strlen_sort($a, $b)

{

    if(strlen($a) > strlen($b))

    {

        return -1;

    }

    else if(strlen($a) < strlen($b))

    {

        return 1;

    }

    return 0;

}

$keys = array(

    'one' => '1', 'two' => '2', 'three' => '3', 'four' => '4', 'five' => '5', 'six' => '6', 'seven' => '7', 'eight' => '8', 'nine' => '9',

    'ten' => '10', 'eleven' => '11', 'twelve' => '12', 'thirteen' => '13', 'fourteen' => '14', 'fifteen' => '15', 'sixteen' => '16', 'seventeen' => '17', 'eighteen' => '18', 'nineteen' => '19',

    'twenty' => '20', 'thirty' => '30', 'forty' => '40', 'fifty' => '50', 'sixty' => '60', 'seventy' => '70', 'eighty' => '80', 'ninety' => '90',

    'hundred' => '100', 'thousand' => '1000', 'million' => '1000000', 'billion' => '1000000000'

);

preg_match_all('#((?:^|and|,| |-)*(\b' . implode('\b|\b', array_keys($keys)) . '\b))+#i', $str, $tokens);

//print_r($tokens); exit;

$tokens = $tokens[0];

usort($tokens, 'strlen_sort');

foreach($tokens as $token)

{

    $token = trim(strtolower($token));

    preg_match_all('#(?:(?:and|,| |-)*\b' . implode('\b|\b', array_keys($keys)) . '\b)+#', $token, $words);

    $words = $words[0];

    //print_r($words);

    $num = '0'; $total = 0;

    foreach($words as $word)

    {

        $word = trim($word);

        $val = $keys[$word];

        //echo "$val\n";

        if(bccomp($val, 100) == -1)

        {

            $num = bcadd($num, $val);

            continue;

        }

        else if(bccomp($val, 100) == 0)

        {

            $num = bcmul($num, $val);

            continue;

        }

        $num = bcmul($num, $val);

        $total = bcadd($total, $num);

        $num = '0';

    }

    $total = bcadd($total, $num);

    echo "$total:$token\n";

    $str = preg_replace("#\b$token\b#i", number_format($total), $str);

}

echo "\n$str\n";
