See getLanguage in JFactory:

请参阅JFactory 中的 getLanguage：

$lang = JFactory::getLanguage();
echo 'Current language is: ' . $lang->getName();

Once you have the language, you can also retrieve the locale/language code (e.g. en-US). Joomla! languages can have multiple locales, so you'll get an array.

获得语言后，您还可以检索区域设置/语言代码（例如en-US）。乔姆拉！语言可以有多个语言环境，所以你会得到一个数组。

$lang = JFactory::getLanguage();
foreach($lang->getLocale()  as  $locale) {
    echo 'This language supports the locale: ' . $locale;
}

If for some reason, you are only interested in the first locale, you can simply grab the first element. You will probably need an array, like this:

如果出于某种原因，您只对第一个语言环境感兴趣，您可以简单地获取第一个元素。您可能需要一个数组，如下所示：

$lang = JFactory::getLanguage();
$locales = $lang->getLocale();
echo 'This language\'s first locale is: ' . $locales[0];

If you just want to get the selected language tag (e.g. pt-PT) you can use getTag()

如果您只想获取选定的语言标签（例如 pt-PT），您可以使用 getTag()

$lang = JFactory::getLanguage();
echo 'Current language is: ' . $lang->getTag();

In Joomla 3.4+, the answer by @MvanGeest still works. Here's a list of useful functions that exist on the language object:

在 Joomla 3.4+ 中，@MvanGeest 的答案仍然有效。以下是语言对象上存在的有用函数的列表：

• Get a handle on the current language through an object of type JLanguage

  $currentLanguage = JFactory::getLanguage();
  

• Get the current language name:

  $currentLanguageName = $currentLanguage->get('name');
  
  //OR
  
  $currentLanguageName = $currentLanguage->getName();
  

• Check if RTL (which is the case of the Arabic language and some other languages)

  $isRTL = $currentLanguage->get('rtl');
  
  //OR
  
  $isRTL = $currentLanguage->isRtl();
  

• Get the current language tag:

  $currentTag = $currentLanguage->get('tag');
  
  //OR
  
  $currentTag = $currentLanguage->getTag();
  

• Get a list of all the known languages:

  $arrLanguages = $currentLanguage->getKnownLanguages();
  

• 通过类型对象获取当前语言的句柄 JLanguage

  $currentLanguage = JFactory::getLanguage();
  

• 获取当前语言名称：

  $currentLanguageName = $currentLanguage->get('name');
  
  //OR
  
  $currentLanguageName = $currentLanguage->getName();
  

• 检查 RTL（这是阿拉伯语和其他一些语言的情况）

  $isRTL = $currentLanguage->get('rtl');
  
  //OR
  
  $isRTL = $currentLanguage->isRtl();
  

• 获取当前语言标签：

  $currentTag = $currentLanguage->get('tag');
  
  //OR
  
  $currentTag = $currentLanguage->getTag();
  

• 获取所有已知语言的列表：

  $arrLanguages = $currentLanguage->getKnownLanguages();
