ThinkPHP多语言在分组下的用法!
参考:http://www.coderblog.in/2010/11/thinkphp-multilingual-with-group.html

ThinkPHP2.0开始就可以支持项目分组,分组的好处是可以让整个项目层次更加清晰,也许是因为习惯了.net的清晰分层,所以我觉得在一个项目里,不管大小,都应该层次分明,这样方便管理之余也方便代码的分离。

ThinkPHP的分组功能可让你分别创建多个目录以对应不同的分组,如可分为 Admin 和 Home 2个组,就可以在 Action 下建立不同的目录,感觉这样是挺清晰方便的。不过也正是因为使用了分组功能,导致在多语言项目时就会出现些预想不到的问题了,总是找不到对应的语言文件来解释,所有标签都直接输出大写了。

开始一直找不出问题,写法都没错的啊,感觉这点官方的手册上说得并不清楚哦,如果按手册上做,根本出不来效果,然后只好直接跟踪源码查看个究竟了。

其实如果查看一下检测多语言的那段代码就会很清楚是怎么回事了,此代码是在 ThinkPHP/Lib/Think/Core/App.class.php ,以下是主要的代码:

// 不开启语言包功能,仅仅加载框架语言文件直接返回
if (!C('LANG_SWITCH_ON')){
  L(include THINK_PATH.'/Lang/'.$langSet.'.php');
  return;
}

刚开始就是卡在这里了,如果要使用自己定义的语言,这个选择必须打开,然后就是语言文件的路径存放问题,继续往下看:


// 定义当前语言
define('LANG_SET',strtolower($langSet));
// 加载框架语言包
if(is_file(THINK_PATH.'/Lang/'.LANG_SET.'.php'))
   L(include THINK_PATH.'/Lang/'.LANG_SET.'.php');
// 读取项目公共语言包
if (is_file(LANG_PATH.LANG_SET.'/common.php'))
   L(include LANG_PATH.LANG_SET.'/common.php');
$group = '';
// 读取当前分组公共语言包
// 例如定义了分组GROUP_NAME为Admin,则路径为:
// 当前项目路径/zh-cn/Admin/lang.php
if (defined('GROUP_NAME')){
   $group = GROUP_NAME.C('TMPL_FILE_DEPR');
   if (is_file(LANG_PATH.LANG_SET.'/'.$group.'lang.php'))
       L(include LANG_PATH.LANG_SET.'/'.$group.'lang.php');
}
// 读取当前模块语言包
// 例如当前为为MemberAction模块,则模块名为:Member,语言文件名为:member.php(文件名为小写)
if (is_file(LANG_PATH.LANG_SET.'/'.$group.strtolower(MODULE_NAME).'.php'))
   L(include LANG_PATH.LANG_SET.'/'.$group.strtolower(MODULE_NAME).'.php'); 


看完后就应该非常清楚了吧,呵,如果定义了分组,就必须按以下目录结构和规则命名:



Lang
  -- 语言编码如(zh-cn)
  -- 分组名
     --模块名.php
     --lang.php(此为本组的公共语言包)

还是举个例比较好理解,如我项目分为2组:
Admin, Home,在Admin下有一个名为 LoginAction.class.php 的操作,现要为Admin下创建多语言包,那么目录结构应该为:


Lang
-- zh-cn
  -- Admin
     -- login.php (对应login操作)
     -- lang.php (Admin下的公共语言)


当然,最后别忘记要打开LANG_SWITCH_ON的配置,否则就全部返回大写了:

LANG_SWITCH_ON => true

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.
