 *      在开发中,首先需要创建一个小助手函数,目录在\include\helpers中
 *  例如,我们创建一个示例为test.helper.php,文件基本内容如下:
 *  <code>
 *  if ( ! function_exists('HelloDede'))
 *  {
 *      function HelloDede()
 *      {

 *  </code>
 *  则我们在开发中使用这个小助手的时候直接使用函数helper('test');初始化它
 *  然后在文件中就可以直接使用:HelloDede();来进行调用.
 *
 * @access    public
 * @param     mix   $helpers  小助手名称,可以是数组,可以是单个字符串
