php xml problem

I have the following code:

<?php
      //includes
      include('conf.php');
      
      $connection = mysql_connect($host, $user, $pass)
      or die ('Unable to connect!');

      function add_to_queue( $func, $arg )
      {
            global $db;
            
            $dom = new DomDocument();
            $root = $dom->createElement( "arguments" );
            foreach( $args as $argtext )
            {
                  $arg = $dom->createElement( "argument" );
                  $arg->appendChild( $dom->createTextNode( $artext ) );
                  $root->appendChild( $arg );
            }            
            $dom->appendChild( $root );
            
            $sth = $db->prepare( "INSERT INTO queue VALUES ( 0, ?, ? )" );
            $db->execute( $sth, array( $func, $dom->saveXML() ) );
      }

      function run_queue()
      {
            global $db;
            
            $delsth = $db->prepare( "DELETE FROM queue VALUES ( 0, ?, ? )" );
            
            $res = $db->query( "SELECT id, func, args FROM queue" );
            while( $res->fetchInto($row) )
            {
                  $id = $row[0];
                  $func = $row[1];
                  $argxml = $row[2];
                  
                  $dom = new DomDocument();
                  $dom->loadXML( $argxml );
                  $arg = array();
                  foreach( $dom->getElementsByTagName( "argument" ) as $node )
                  {
                        $arg []= $node->nodeValue;
                  }
                  
                  call_user_func_array( $func, $args );
                  
                  $db->execute( $delsth, array( $id ) );
            }
      }
?>

I am using a server that is running php version 4.4.2 and I need to get this script to work... it is obviously a php 5 script (DomDocumet();).  How would I convert it?

Have a look at PHP4 XML functions http://www.php.net/manual/en/ref.domxml.php

How important is it that the $arg be stored as XML?

If it's not important at all, use serialize($arg) to convert the PHP values into a string, and unserialize($str) to convert the string back into an array of values.

If using XML is important, then this won't help.  

The XML looks gratuitous to me :-)

     function add_to_queue( $func, $arg )
     {
          global $db;          
          $sth = $db->prepare( "INSERT INTO queue VALUES ( 0, ?, ? )" );
          $db->execute( $sth, array( $func, serialize($arg) ) );
     }

     function run_queue()
     {
          global $db;
         
          $delsth = $db->prepare( "DELETE FROM queue VALUES ( 0, ?, ? )" );
         
          $res = $db->query( "SELECT id, func, args FROM queue" );
          while( $res->fetchInto($row) )
          {
               call_user_func_array( $row[1],  unserialize($row[2]) );
               $db->execute( $delsth, array( $row[0] ) );
          }
     }

Yea... After sleeping on it the xml does seem like overkill... I think I'm going to go for the serialize route... thanks for the help.
