php - 如何使用 php 和 codeigniter 在 mysql 中导入 CSV 文件？

Question

我正在为一家销售公司开发一个网站。我想添加大量员工数据，这将是一个 CSV 文件。我需要帮助。一个代码示例将不胜感激，因为我是这方面的新手。此代码应先上传 CSV，然后将其导入 MySQL。提前致谢！

有一个带有文件上传表单的视图，然后有一个带有控制器调用的上传函数的 csv_model。这个函数应该包含看起来有点像这样的代码：

    if (isset($_FILES['userfile']) && $_FILES['userfile']['size'] > 0 && $_FILES['userfile']['error'] == 0) {
        // Upload the file:         
        if (!is_dir($this->upload_path)) mkdir($this->upload_path,0777,TRUE);
        $config['upload_path'] = $this->upload_path;
        $config['allowed_types'] = 'csv';
        $this->load->library('upload', $config);

        if ( ! $this->upload->do_upload())
        {
            $error = array('error' => $this->upload->display_errors());
            echo 'Error: '; print_r($error); die();
            return $error;
        }
        else
        {
        // It's uploaded, so open it, loop through it and do what you need to do
            $data = array('upload_data' => $this->upload->data());
            $file_path = $data['upload_data']['full_path'];
             $row = 1;
             $db_row = array();
             if (($handle = fopen($file_path, "r")) !== FALSE) {
                while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
                    $num = count($data);
                    $db_row[$row]['xxx'] = $data[0];
                    // Any database insertion goes here...
                }
             }

         }}
