PHP Dal::get_connection方法代码示例

 /**
  * Updated search method for users. Search type can also be specified with every field one is searching for
  * e.g $search_item['first_name'] = array('value'=> 'test', 'type'=> LIKE_SEARCH) here type defines the search type
  * in this case it is LIKE SEARCH (constant defined in api_constants.php) means value
  * will be searched field_value = '%test%'
  * For date of birth we can specify date range like $search_item['dob'] = array('value'=>
  * array('lower_limit'=>200400, 'upper_limit'=>300500), 'type'=> RANGE_SEARCH)
  * This method will help us to search for value given in range and will give more freedom than the
  * method load_info_by_search which uses only LIKE to search for values.
