-hi我需要通过循环从表中加载数据。请帮我 - 如何从数据库生成xml文件？

Answer 1

从数据库生成xml文件很简单。你不需要循环就行了。

模型功能

function getDataForXML(){
   return $query = $this->db->get('my_table');
   //Here you should note i am returning 
   //the query object instead of 
   //$query->result() or $query->result_array()
}

控制器

function get_report()
{
    $this->load->model('my_model');
    $this->load->dbutil();
    $this->load->helper('file');
    // get the object
    $report = $this->my_model->getDataForXML();
    //pass it to db utility function
    $new_report = $this->dbutil->xml_from_result($report);
    //Now use it to write file. write_file helper function will do it
    write_file('xml_file.xml',$new_report);
    //Done
}

现在可以使用名为xml_file.xml的新文件了！

资源

Database Utility Class

并且
