srcmini本文概述
编程的目标是多目标优化, 我们编写代码来自动完成需要一些时间才能手动完成的事情。对于许多项目, 你需要将数字转换为其单词表示形式, 以防止用户将整个数字写成单词(例如, 带有单词的数字123456789将为一亿二千三百万, 四十五万六千七, 七一百八十九)。是的, 这是一个非常长的数字, 我知道你甚至都没有读完整的数字, 所以, 你的用户为什么要自己写呢？通过在服务器端使其自动化, 使你的用户容易完成此任务。在本文中, 你将学习使用Symfony 3项目中的numbers_words包将数字转换为其单词表示形式。
要求
为了将数字转换为单词, 我们将使用PEAR的numbers_words包。此类可以将整数更改为简单的单词。当你需要拼写货币值(例如, 在发票上。该软件包提供对20多种语言的支持, 包括英语, 德语, 西班牙语, 瑞典语, 土耳其语, 俄语和其他语言。根据最后的测试, 它最多可以转换14位数字的值。
安装
要将项目中的numbers_words作为依赖项添加, 请在终端中执行以下命令：
composer require pear/numbers_words或修改项目的composer.json文件, 手动添加依赖项, 然后执行composer install：
{
"require": {
"pear/numbers_words": "^0.18.1"
}
}安装后, 你将可以通过导入Numbers_Words类在项目中使用该软件包。
用法
Numbers_words类提供了toWords的静态方法。此方法期望将要转换为单词的整数作为第一个参数, 并将期望的语言的语言标识符作为第二个参数, 例如英语：
<?php
namespace AppBundle\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;
// Import the class
use Numbers_Words;
class DefaultController extends Controller
{
/**
* @Route("/", name="homepage")
*/
public function indexAction()
{
$numberToConvert = 99999999999999;
$localeEnglish = "en_US"; // Or en_GB
$wordsFromValue = Numbers_Words::toWords($numberToConvert, $localeEnglish);
return new Response($wordsFromValue);
}
}
前任控制者的响应将是990万亿999 990亿990 9.9亿。
其他语言
如前所述, 该软件包提供了对20多种语言的支持。你只需在静态方法中为你的语言代码提供第二个参数即可(有关更多代码, 请访问存储库)：
<?php
namespace AppBundle\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;
// Import the class
use Numbers_Words;
class DefaultController extends Controller
{
/**
* @Route("/", name="homepage")
*/
public function indexAction()
{
$numberToConvert = 123456789;
$supportedLanguages = array(
array("languageName" => "Bulgarian", "languageCode" => "bg"), array("languageName" => "German", "languageCode" => "de"), array("languageName" => "Danish", "languageCode" => "dk"), array("languageName" => "Donald Knuth number naming system", "languageCode" => "en_100"), // notation of numbers, where one billion is 1000000 times one million.
// 1000 times million is just 'thousand million' here. The word billiard here is not used
// because English people do not use it often, and even could not know it.
array("languageName" => "British English", "languageCode" => "en_GB"), array("languageName" => "American English", "languageCode" => "en_US"), array("languageName" => "Spanish (Castellano)", "languageCode" => "es"), array("languageName" => "Spanish Argentinian", "languageCode" => "es_AR"), array("languageName" => "French ", "languageCode" => "fr"), array("languageName" => "French (Belgium)", "languageCode" => "fr_BE"), array("languageName" => "Hebrew", "languageCode" => "he"), array("languageName" => "Indonesia", "languageCode" => "id"), array("languageName" => "Italian", "languageCode" => "it_IT"), array("languageName" => "Lithuanian ", "languageCode" => "lt"), array("languageName" => "Dutch ", "languageCode" => "nl"), array("languageName" => "Polish", "languageCode" => "pl"), array("languageName" => "Brazilian ", "languageCode" => "pt_BR"), array("languageName" => "Romanian ", "languageCode" => "ro_RO"), array("languageName" => "Russian ", "languageCode" => "ru"), array("languageName" => "Turkish ", "languageCode" => "tr_TR")
);
$responseString = "";
foreach($supportedLanguages as $language){
$convertedNumber = Numbers_Words::toWords($numberToConvert, $language["languageCode"]);
$responseString .= $language["languageName"] . " : ". $convertedNumber . "<br>";
}
$response = new Response($responseString);
$response->setCharset('UTF-8');
$response->headers->remove('Cache-Control');
$response->headers->set('Content-Type', 'text/html');
return $response;
}
}响应将是：
