php语言翻译功能 [英] php function for language translation

问题描述

对于CMS的多语言使用，它们通过类似于以下功能的功能来翻译术语

For multi-language usage of CMS, they translate terms by a function similar to

function __($word) {
include 'fr.php';
if(!empty($lang[$word])) {$translated=$lang[$word];
} else {
$translated = $word;
} 
return $translated;
}

1. 由于我们需要在php页面中多次使用此功能，因为所有单词和短语都将被__('')回显；该函数是否需要每次都包含语言时间，否则将在首次加载后为该函数缓存?

1. Since we need to use this function several times in a php page, as all words and phrases will be echoed by __(' '); does the function need to include the language time every time, or it will be cached for the function after first load?

由于语言文件包含整个网站上使用的单词和短语的完整列表(数千个键/值)，因此pho需要在每次访问页面时将此长数组加载到内存中.将多语言功能添加到CMS真的是最好的方法吗?

Since the language file contains a complete list of words and phrased used throughout the website (thousands of key/value), pho needs to load this long array into memory every time a page is visited. Is it really the best approach to add multi-language feature to a CMS?

推荐答案

如果由于某种原因而不能使用gettext()，那么最好将类似这样的东西放在带有gettext()的对象中包含语言字符串作为静态数组，例如:

If you can't use gettext() for some reason, you'd be better off, with something like this, to put it into an object with the included language strings as a static array, something like:

class Message {

  private static $_messages = array();

  public static function setMessageLibrary($sMessageLibrary) {
    require_once $sMessageLibrary;
    self::$_messages = $aMsgs;
  }

  public static function getMessage($sMessageId) {
    return isset(self::$_messages[$sMessageId]) ? self::$_messages[$sMessageId] : "";
  }
}

您的消息库文件(包含在setMessageLibrary()静态函数中)，每种语言都将包含一个消息库文件，其中需要一个名为$aMsgs的变量，该变量可能类似于:

Your message library file (included with the setMessageLibrary() static function), of which you'll have one per language, will need a variable in it called $aMsgs which might look something like:

// Messages for fr-FR
$aMsgs = array(
  'hello_everybody' => "Bonjour tout le monde"

  ...

  and so on
);

由于全部是静态的，但是在对象内部，因此可以通过在脚本的开头进行设置来有效地缓存包含的语言文件.

Since it's all static but within the object you can effectively cache that included language file by setting it at the start of your script.

<?php
Message::setMessageLibrary('/lang/fr-FR/messages.inc.php');
echo Message::getMessage('hello_world');
echo Message::getMessage('another_message');
echo Message::getMessage('yet_another_message');
?>

然后，所有三个消息将引用存储在Message::$_messages

All three messages will then reference the single language array stored in Message::$_messages

这里没有卫生措施，也没有健全性检查，但这仍然是基本原则……如果您不能使用gettext();)

There's no sanitisation, nor sanity checks in there, but that's the basic principle anyway ... if you can't use gettext() ;)
