PHP QApplication::SetErrorHandler方法代码示例

 /**
  * Same as mkdir but correctly implements directory recursion.
  * At its core, it will use the php MKDIR function.
  * This method does no special error handling.  If you want to use special error handlers,
  * be sure to set that up BEFORE calling MakeDirectory.
  *
  * @param         string  $strPath actual path of the directoy you want created
  * @param         integer $intMode optional mode
  *
  * @return         boolean        the return flag from mkdir
