    Generating XML using PHP issues

    Hi all,

    I need some of your help, I'm working on my PHP script to create the XML document with encoding utf8 so I can generate the XML file to allow me to save the XML file in my web host.


    I want to make the xml output to something like this:

    Code:
    <?xml version="1.0" encoding="UTF-8" ?>
    <tv generator-info-name="www.mysite.com/xmltv">
    <channel id="">
       <display-name>Information from database</display-name>
       <programme channel="Information from database" start="" stop="">
           <title lang="en"></title>
           <sub-title lang="en">
           </sub-title>
           <desc lang="en"></desc>
           <category lang="en"></category>
       </programme>
    </channel>


    Here's what my XML output looks like:

    Code:
    <?xml version="1.0" encoding="UTF-8"?>
    <tv generator-info-name="www.mysite.com/xmltv"><channel><display-name>Information from database</display-name><programme/><desc/></channel></tv>

    Here's the current code:

    Code:
    <?php
    
    function db_connect()
    {
      define('DB_HOST', 'localhost');
      define('DB_USER', 'myusername');
      define('DB_PASSWORD', 'mypassword');
      define('DB_DATABASE', 'mydbname');
          
      $errmsg_arr = array();
      $errflag = false;
      $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
      
      if(!$link) 
      {
        die('Failed to connect to server: ' . mysql_error());
      }
    
      $db = mysql_select_db(DB_DATABASE);
      if(!$db) 
      {
        die("Unable to select database");
      }
    }
    db_connect();
    
      function clean($var)
      {
        return mysql_real_escape_string(strip_tags($var));
      } 
      $channels = clean($_GET['channels']);
      $id = clean($_GET['id']);
      
      if($errflag) 
      {
        $_SESSION['ERRMSG_ARR'] = $errmsg_arr;
        echo implode('<br />',$errmsg_arr);
      }
      else 
      {
        $insert = array();
      
        if(isset($_GET['channels'])) 
        {
          $insert[] = 'channels = \'' . clean($_GET['channels']) .'\'';
        }
        if(isset($_GET['id'])) 
        {
          $insert[] = 'id = \'' . clean($_GET['id']) . '\'';
        }
        
        
        if($channels && $id) 
        {
          $qrytable1="SELECT id, channels, links FROM tvguide WHERE channels='$channels' && id='$id'";
          $result1=mysql_query($qrytable1) or die('Error:<br />' . $qry . '<br />' . mysql_error());
          echo '<?xml version="1.0" encoding="UTF-8" ?>
    <tv generator-info-name="www.mysite.com/xmltv">
    <channel id="">
       <display-name></display-name>
       <programme channel="" start="" stop="">
          <title lang="en"></title>
          <sub-title lang="en"></sub-title>
          <desc lang="en"></desc>
          <category lang="en"></category>
       </programme>
    </channel>
    </tv>';
    	
          while ($row = mysql_fetch_array($result1))
          {
            
          }
          mysql_close();
        }
        else if(!$channels && ! $id) 
        {
          $qrytable1="SELECT id, channels, links, streams FROM tvguide";
          $result1=mysql_query($qrytable1) or die('Error:<br />' . $qry . '<br />' . mysql_error());
    
    	
          while ($row = mysql_fetch_array($result1)) 
          {
            
          }
          mysql_close();
        }
      }
      // create a dom document with encoding utf8
      $domtree = new DOMDocument('1.0', 'UTF-8');
    
      // create a root element of the xml tree
      $tv = $domtree->createElement('tv');
    
        //create attributes for element
        $generator_info_name = $domtree->createAttribute('generator-info-name');
        $generator_info_name->value = 'mysite.com/xmltv';
        //append attribute
        $tv->appendChild($generator_info_name);
        // append element to the doc
        $tv = $domtree->appendChild($tv);
    
        //add a channel as a child of the root
        $channel = $domtree->createElement('channel');
        $channel_id = $domtree->createAttribute('id');
        $channel_id->value = '""';
        $channel = $tv->appendChild($channel);
    
            //append children to channel
            $channel->appendChild($domtree->createElement('display-name','Information from database'));
            $channel->appendChild($domtree->createElement("programme"));
            $channel->appendChild($domtree->createElement('desc'));
    
        //finally, save the file
        echo $domtree->saveXML();
        $domtree->save('myChannel.xml');
    ?>


    Do you know how I can make the same XML output as the first code?

    And how I can output for each data from mysql database to put it in each channel tag and I want to add the tags under the channel tag including the display-name, programme-channel, title, sub-title, desc and category tags when I output for each data from mysql?

    Any advise would be much appreciated.

    Thanks in advance
