FAQ
Joomla support multi-language?
Yes
在组件中如何加载其他扩展的语言文件?
开发一个Joomla投稿组件的时候，需要调用joomla文章组件的语言文件，因为界面很多字符串都来自系统的文章组件，本来打算直接将系统的文章组件的语言文件直接复制一份的，但感觉那样做不优雅，因此，查了一下源码，发现是Joomla是可以在任何时间，任何地方调用任何组件的语言文件的。
直接上代码了，并不难理解
`$lang` `= JFactory::getLanguage();`
`$extension` `= ``'com_content'``;`
`$base_dir` `= JPATH_ADMINISTRATOR;`
`$language_tag` `= ``'zh-CN'``;`
`$reload` `= true;`
`$lang``->load(``$extension``, ``$base_dir``, ``$language_tag``, ``$reload``);`
上面的代码没有什么好解释的。需要什么扩展就将extension变量赋值即可。
如何设置数据库默认连接？
