Question

我想将表导出到csv文件。该文件应保存到资产中的文件夹。在这里我使用强制下载。如何设置下载csv文件的路径？还有其他方法将表保存为csv文件到指定的文件夹。请帮帮我..

    $this->load->dbutil(); 
        $this->load->helper('file'); 

        $this->load->helper('download');
        $delimiter = ","; 
        $newline = "\r\n";
        $filename = "filename.csv";  
        $query = "SELECT * FROM cyber_details";
        $result = $this->db->query($query);
        $data = $this->dbutil->csv_from_result($result, $delimiter, $newline);
        force_download($filename, $data);

Answer 1

试试这个，为我工作：

function createcsv(){
        $this->load->dbutil();
        $this->load->helper('file');
        $this->load->helper('download');
        $delimiter = ",";
        $newline = "\r\n";
        $filename = "filename.csv";
        $query = "SELECT * FROM YourTable";
        $result = $this->db->query($query);
        $data = $this->dbutil->csv_from_result($result, $delimiter, $newline);
        force_download($filename, $data);

    }

我假设您要在服务器端保存CSV文件。

您可以按照以下方式执行

    $this->load->dbutil(); 
    $this->load->helper('file'); 

    $this->load->helper('download');
    $delimiter = ","; 
    $newline = "\r\n";
    $filename = "filename.csv";  
    $query = "SELECT * FROM cyber_details";
    $result = $this->db->query($query);
    $data = $this->dbutil->csv_from_result($result, $delimiter, $newline);
    if ( ! write_file('./path/to/file/file_name.csv', $data))
    {
       echo 'Unable to write the file';
    }
    else 
   {
     echo 'File written!';
   }

确保您选择的路径具有足够的权限来执行写入操作。

我也遇到了同样的问题。下面的代码对我来说足够好。

$arry_to_csv[] = $data;
$output_file_name = 'path/to/Rejected.csv';
    $temp_memory = fopen($output_file_name, 'w');
    $csv_headers = array_keys($arry_to_csv[0]);
    $delimiter = ",";
    fputcsv($temp_memory, $csv_headers, $delimiter);
    $csv = '';
    foreach ($arry_to_csv as $line) {
        $csv.= $line['first_name'] . ',' . $line['last_name'] . "\n";
    } 
    fwrite($temp_memory, $csv);
    fclose($temp_memory);
