你非常在轨道上，除了一个位，你的数据和代码交织在一起，这不是一个好的设计形式。不同的人使用不同的方法来处理I18N。我更喜欢使用.INI文件，你可以在不同的INI文件中拥有数据，甚至可以添加部分，如果你想的话。使用您的示例，您可以执行以下操作：

--en.ini

PAGE_TITLE = 'My website page title'
HEADER_TITLE = 'My website header title'
SITE_NAME' = 'My Website'
SLOGAN = 'My slogan here'
HEADING = 'Heading'

--it.ini

PAGE_TITLE = 'Il titolo della mia pagina'
HEADER_TITLE = 'Il mio titolo'
SITE_NAME = 'Il nome del mio sito'
SLOGAN = 'Uno slogan'
HEADING = 'Heading'

<?php

class Language {

private $UserLng;
private $langSelected;
public $lang = array();


public function __construct($userLanguage){

    $this->UserLng = $userLanguage;
    //construct lang file
    $langFile = '/path/to/ini/files/'. $this->UserLng . '.ini';
    if(!file_exists($langFile)){
        throw new Execption("Language could not be loaded"); //or default to a language
    }

    $this->lang = parse_ini_file($langFile);
}

public function userLanguage(){
    return $this->lang;
}

}
