使用CodeIgniter创建XML

Question

I'm using this code in Codeigniter to generate XML:

public function get_cuisine()
{
    $this->load->dbutil();
    $sql = "select * from cuisine";
    $query = $this->db->query($sql);
    $config = array (
        'root'    => 'root',
        'element' => 'element',
        'newline' => "\n",
        'tab'     => "\t"
    );
    echo $this->dbutil->xml_from_result($query, $config);   
}   

But this shows the general print format. How can I get it to show as an XML type page?

You'll need to set XML headers if you want to output the file directly:

Using the Codeigniter Output class :

$xml = $this->dbutil->xml_from_result($query, $config);
$this->output->set_content_type('text/xml');
$this->output->set_output($xml); 

Or you can use plain PHP to set the headers :

header('Content-type: text/xml');
echo $this->dbutil->xml_from_result($query, $config);

Or you can use the CI download helper :

$xml = $this->dbutil->xml_from_result($query, $config);
$this->load->helper('download');
force_download('myfile.xml', $xml);

Or write it to a file with the file helper :

$xml = $this->dbutil->xml_from_result($query, $config);
$this->load->helper('file');
$file_name = '/path/to/myfile.xml';
write_file($file_name, $xml);
// Optionally redirect to the file you (hopefully) just created
redirect($file_name);

I had also the same question. I have googled it. Found this solution. And it works perfectly for me. Click here to get the source code

Just download and unzip ( extract it)

Then copy the xml_writer.php in application->libraries of the extracted folder to your libraries folder in your Codeigniter project.

Also copy the xml.php in the application->controller in to your controllers folder

Finally copy the xml.php in the views of the extracted folder in to your view and run it..

That's it...

Custom solution:

$mysql_data = $this->db->get('products')
                    ->result_array();
$xml = '<root>';
foreach($mysql_data as $row){
  $xml .= '<item>
             <name>'.$row['title'].'</name>
             <price>'.$row['price'].'</price>
             <image>'.$row['pic'].'</image>
           </item>';
}
$xml .= '</root>';
$this->output->set_content_type('text/xml');
$this->output->set_output($xml);
