Question

我想将数据从数据库导出到csv。这是我的代码

public function export_product_to_csv()
{
    $response = new stdClass();
    $response->success = TRUE;
    $response->message = "Terjadi kesalah saat proses export. Silakan hubungin administartor";
    $this->load->dbutil();
    $this->load->helper('file');
    $this->load->helper('download');
    $delimiter = ",";
    $newline = "\r\n";
    $filename = "list_item.csv";
    $query = "SELECT * FROM `list_item` ";
    $result = $this->db->query($query);
    $data = $this->dbutil->csv_from_result($result, $delimiter, $newline);
    $download = force_download($filename, $data);
    if ($download) {
        $response->message = "Export Berhasil ";
        $response->link = $this->generate_activity_link("view_product_management","Export Product");
        $response->success = TRUE;
    } else {
        $response->message = "Gagal . Query salah.";
    }
  return $response;   
}

但是当我执行代码时它会返回

＆＃34; ITEM_ID＆＃34;＆＃34; ITEM_CODE＆＃34;＆＃34; TYPE_ID＆＃34;＆＃34; ref_number＆＃34;＆＃34; ITEM_NAME＆＃34;＆＃ 34;价格＆＃34;＆＃34; qty_perpack＆＃34;＆＃34; label_code＆＃34;＆＃34; CLIENT_ID＆＃34; ＆＃34; 1＆＃34;＆＃34; RL30CM＆＃34;＆＃34; 5＆＃34;＆＃34; ＆＃34;，＆＃34; Pengaris 30 Cm＆＃34;，＆＃34; 1500＆＃34;，＆＃34; 150＆＃34;，＆＃34; TX30CM＆＃34;，＆＃34; 0＆＃34 ; ＆＃34; 2＆＃34;，＆＃34; VP00＆＃34;，＆＃34; 5＆＃34;，＆＃34;＆＃34;，＆＃34; Ventplug dengan karet＆＃34;，＆＃ 34; 2000＆＃34;＆＃34; 2000＆＃34;＆＃34; TXVP0＆＃34;＆＃34; 1＆＃34; ＆＃34; 3＆＃34;，＆＃34; PP Merah＆＃34;，＆＃34; 1＆＃34;，＆＃34;＆＃34;，＆＃34; Bahan coba＆＃34;，＆＃34; ; 15000＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;＆＃34; 0＆＃34; ＆＃34; 4＆＃34;＆＃34; TNVA＆＃34;＆＃34; 5＆＃34;＆＃34; ＆＃34;，＆＃34; Antena Tv＆＃34;，＆＃34; 15000＆＃34;，＆＃34; 1000＆＃34;，＆＃34; TXTVNA＆＃34;，＆＃34; 2＆＃34; ＆＃34; 5＆＃34;，＆＃34; YZHAA＆＃34;，＆＃34; 5＆＃34;，＆＃34;＆＃34;，＆＃34;测试barang＆＃34;，＆＃34; ; 1500＆＃34;＆＃34 1000＆＃34;＆＃34; TEST＆＃34;＆＃34; 2＆＃34; ＆＃34; 6＆＃34;，＆＃34; YHASA＆＃34;，＆＃34; 5＆＃34;，＆＃34;＆＃34;，＆＃34; Pengaris 20 Cm＆＃34;，＆＃34 ; 2000＆＃34;＆＃34; 1000＆＃34;＆＃34; UZYA＆＃34;＆＃34; 2＆＃34; ＆＃34; 7＆＃34;，＆＃34; PP Hitam＆＃34;，＆＃34; 1＆＃34;，＆＃34;＆＃34;，＆＃34; PP Hitam＆＃34;，＆＃34; ; 15000＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;＆＃34; 0＆＃34; ＆＃34; 8＆＃34;，＆＃34; PP002＆＃34;，＆＃34; 1＆＃34;，＆＃34;＆＃34;，＆＃34; Biji plastik hijau＆＃34;，＆＃ 34; 200000＆＃34;＆＃34;＆＃34;＆＃34; PPGR＆＃34;＆＃34; 2＆＃34; ＆＃34; 9＆＃34;，＆＃34; BBW＆＃34;，＆＃34; 4＆＃34;，＆＃34;＆＃34;，＆＃34; Bubble Wrapper＆＃34;，＆＃34; 75000＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;＆＃34; 0＆＃34;

不下载面板。请帮帮我

使用此方法并根据您的要求进行排列。我已经多次使用它，它一直对我有用

//get records from database
$query = $db->query("SELECT * FROM list_item ORDER BY id DESC");

if($query->num_rows > 0){
    $delimiter = ",";
    $filename = "file_name_" . date('Y-m-d') . ".csv";

    //create a file pointer
    $f = fopen('php://memory', 'w');

    //set column headers
    $fields = array('ID', 'Name', 'Email', 'Phone', 'Created', 'Status');
    fputcsv($f, $fields, $delimiter);

    //output each row of the data, format line as csv and write to file pointer
    while($row = $query->fetch_assoc()){
        $status = ($row['status'] == '1')?'Active':'Inactive';
        $lineData = array($row['id'], $row['name'], $row['email'], $row['phone'], $row['created'], $status);
        fputcsv($f, $lineData, $delimiter);
    }

    //move back to beginning of file
    fseek($f, 0);

    //set headers to download file rather than displayed
    header('Content-Type: text/csv');
    header('Content-Disposition: attachment; filename="' . $filename . '";');

    //output all remaining data on a file pointer
    fpassthru($f);
}

Codeigniter，强制下载返回数据而非下载面板
