                  问题描述

                  您好,我正在尝试创建自己的自定义助手类以与 Yii2 一起使用.它将处理时间,所以我将使用 PHP 的 DateTime 类.我有

                  Hello I am trying to create my own custom helper class to use with Yii2. It is going to handle times so I'll be working with PHP's DateTime class. I have

                  <?php
                  
                  namespace yiihelpers;
                  
                  use Yii;
                  
                  class Time
                  {
                      public static function getTime()
                      {  
                      $time = new DateTime('now', new DateTimeZone('UTC'));
                      return $time->format('m-d-Y H:i:s');
                      }
                  }
                  

                  为了测试它,我添加了使用 yiihelpersTime;到一个视图文件并调用 Time::getTime(); 但 Yii2 抛出一个 ErrorException 说 Class 'yiihelpersDateTime' not found.

                  To test it I added use yiihelpersTime; to a view file and called Time::getTime(); but Yii2 throws an ErrorException saying Class 'yiihelpersDateTime' not found.

                  如果我将代码直接放入视图文件并执行它,php DateTime 对象就可以正常工作,所以我不确定我的问题是什么.

                  The php DateTime object works fine if I place the code directly into a view file and execute it so I'm not sure what my problem is.

                  推荐答案

                  在类名中加入一个反斜杠表示它在全局命名空间中:

                  Put a backslash in from of the class name to indicate it is in the global namespace:

                  $time = new DateTime('now', new DateTimeZone('UTC'));
