目前我正在使用以下方法在codeigniter中执行此操作

 function _getXML_Hotellist($fname) {

        $filename = $fname.'.xml';
        $xmlfile='xml/'.$filename;
        $xmlRaw = file_get_contents($xmlfile);
        $xmlData = $this->simplexml->xml_parse($xmlRaw);

        /* database for XMLResponse */

        $result0['ResponseType'] = $xmlData['ResponseType'];
        $result0['AffiliateCode'] = $xmlData['RequestInfo']['AffiliateCode'];
        $result0['AffRequestId'] = $xmlData['RequestInfo']['AffRequestId'];
        $result0['AffRequestTime'] = $xmlData['RequestInfo']['AffRequestTime'];
        $result0['TotalNumber'] = $xmlData['TotalNumber'];

        /* database for Hotel List */

        foreach($xmlData['Hotel'] as $row) {

            $result1['HotelCode']=$this->check_empty($row['HotelCode']);
            $result1['OldHotelId']= $this->check_empty($row['OldHotelId']);

            if(is_array($result1['OldHotelId'])) {
                $result1['OldHotelId']= $result1['OldHotelId'][0];;
            } else {
                $result1['OldHotelId']= $result1['OldHotelId'];
            }

            $result1['DestinationId']= $this->check_empty($row['DestinationId']);
            $result1['Destination']= $this->check_empty($row['Destination']);
            $result1['Country']= $this->check_empty($row['Country']);
            $result1['HotelName']= $this->check_empty($row['HotelName']);
            $result1['StarRating']= $this->check_empty($row['StarRating']);
            $result1['HotelAddress']= $this->check_empty($row['HotelAddress']);
            $result1['HotelPostalCode']= $this->check_empty($row['HotelPostalCode']);
            $result1['HotelPhoneNumber']= $this->check_empty($row['HotelPhoneNumber']);
            $result1['HotelArea']=$this->check_empty($row['HotelArea']);
            $result1['Chain']=$this->check_empty($row['Chain']);

            /* database for Hotels Location */

            $result2['Latitude']=$this->check_empty($row['Coordinates']['Latitude']);
            $result2['Longitude']=$this->check_empty($row['Coordinates']['Longitude']);
            $result2['HotelCode']= $this->check_empty($row['HotelCode']);

            /* database for Hotels Images */

            $result4['HotelCode']= $this->check_empty($row['HotelCode']);
            $result3['ImageURL']=$row['HotelImages']['ImageURL'];

            if(empty($result3['ImageURL'])) {
                $result4['ImageURL']="";
                $this->db->insert('cf_hotel_images',$result4);
            } else {
                if(is_array($result3['ImageURL'])) {
                    foreach($result3['ImageURL'] as $row) { 
                        $result4['ImageURL']=$row;
                        $this->db->insert('cf_hotel_images',$result4);
                    }
                 } else {
                     $result4['ImageURL']= $result3['ImageURL'];
                     $this->db->insert('cf_hotel_images',$result4);
                 }
             }

            /* database Queries */

            $this->db->insert('cf_hotel_list',$result1);
            $this->db->insert('cf_coordinates',$result2);
            }

            //$this->db->insert('cf_xml_response',$result0);
    }

这是有效的，但这很慢，每次都会过期，也会耗费太多时间。所以请建议我另一个解决方案。

Answer 1

像这样插入多个行：

function _getXML_Hotellist($fname) {
   $resToInsert1 = $resToInsert2 = array();
   $rowsCounter = 0;
   foreach($xmlData['Hotel'] as $row) {
      // fill your $result1 and $result2 arrays
      $resToInsert1[] = $result1;
      $resToInsert2[] = $result2;
      $rowsCounter++;
      if ($rowsCounter == 1000) { // for example, you can choose another number
         // insert to db like a
         //  INSERT INTO table (col1, col2) 
         //  VALUES (...),
         //  VALUES (...),
         //  VALUES (...);
         // all data from $resToInsert1 and $resToInsert2
         // and refresh vars
         $resToInsert1 = $resToInsert2 = array();
         $rowsCounter = 0;
      } 
   }
}

UPD。此外，如果您不想丢失数据，可以使用INSERT DELAYED

Answer 2

您应该将数据转换为文件并将其上传到某个位置。然后，不是将数据插入数据库，而是将URL插入文件。

上传大文件不是一个好习惯。它可能会导致MySQL数据库流量过大

将重（大约180mb）XML数据上传到MySQL的最佳方法是什么？
