Populate existing PDF with .xfdf form data stored in database using PHP/MySQL

I have an HTML form that enters the values into a database. I use this PHP/MySQL code to retrieve the data and create the .xfdf form data, then the .xfdf form data is entered into the database:

function CreateXFDF($file,$info,$enc='UTF-8')
{
    $data='<?xml version="1.0" encoding="'.$enc.'"?>'."\n".
          '<xfdf xmlns="http://ns.adobe.com/xfdf/" xml:space="preserve">'."\n".
            '<fields>'."\n";
    foreach($info as $field => $val){
          $data.='<field name="'.$field.'">'."\n";
        if(is_array($val)){
            foreach($val as $opt)
                $data.='<value>'.htmlentities($opt).'</value>'."\n";
        }else{
            $data.='<value>'.htmlentities($val).'</value>'."\n";
        }
        $data.='</field>'."\n";
    }
    $data.='</fields>'."\n".
          '<ids original="'.md5($file).'" modified="'.time().'" />'."\n".
          '<f href="'.$file.'" />'."\n".
          '</xfdf>'."\n";
    return $data;

   require_once('createxFDF.php');
   $id = $_GET['id'];
   $pdf_file='http://XXX.XXX.XXX.XXX/admin/application.pdf';
   include("login.php");
   login();
   $query = "select * from client where id=$id";
   $result = mysql_query($query);
   $row = mysql_fetch_array($result, MYSQL_ASSOC);

   $text_fields=array(
     $row['business_name'],
     $row['business_name2'],
     $row['business_address1'],
     $row['business_address2'],
     $row['legal_name'],
     $row['owner_first'],
     $row['owner_last'],
     $row['legal_phone'],
     $row['legal_fax'],
      );
        // get the xFDF file contents
        $xfdf=createxFDF($pdf_file,$text_fields);
        if (get_magic_quotes_gpc())
         {
          $xfdf = stripslashes($xfdf);
         }
       $xfdf=mysql_real_escape_string($xfdf);

      $query = "INSERT INTO applications SET apps='$xfdf', idnum='$id'";
      $result=mysql_query($query);
This works fine, using phpMyAdmin I can see the correct form data in the database.
Then when I try to retrieve the .xfdf form data from the database the existing PDF form (on the server) opens but the form data does not populate the fields in the form. Code:

   $idnum = $_GET['idnum'];
   include("login.php");
   login();
   $query = "SELECT * from applications where idnum=$idnum";
   $result = mysql_query($query);
   $row=mysql_fetch_array($result, MYSQL_ASSOC);
   $datafile = $row['apps'];
   header("Pragma: cache");
   header("Cache-Control: public");
   header("Content-Description: File Transfer");
   header("Content-type: application/vnd.adobe.xfdf");
   header("Content-Disposition: attachment; filename=application.xfdf");
   header("Expires: 0");
   echo $datafile;

I have based this code on code (which works fine) that takes the HTML field entries and directly populates the existing PDF form; but I need to have this performed from the .xfdf form data in the database not from the HTML form field $_POST values.
I have checked the field names in the PDF form are identical to the field names used to create the .xfdf form data file.
