How to write XML with PHP (without overwriting the xml)

[C0FFEE123]

Hi,

I already posted another thread about how to write XML with PHP.
Well that worked, only if i write a new one it overwrites the old XML file.
I want to add the information in the same XML file only without overwriting it.
How to do that?

The part that writes it to xml:

<?php
// TEST
  $informatie = array();
  $informatie [] = array(
  'Auto' => $_POST['artikel'],
  'Shortd' => $_POST['korte_omschrijving'],
  'Longd' => $_POST['uitgebreide_omschrijving'],
  'Prijs' => $_POST['prijs']);
  
  $doc = new DOMDocument();
  $doc->formatOutput = true;
  
  $r = $doc->createElement( "Informatie" );
  $doc->appendChild( $r );
  
  foreach( $informatie as $info )
  {
  $b = $doc->createElement( "Auto" );
  
  $auto = $doc->createElement( "Auto" );
  $auto->appendChild(
  $doc->createTextNode( $info['Auto'] )
  );
  $b->appendChild( $auto );
  
  $shortd = $doc->createElement( "Shortd" );
  $shortd->appendChild(
  $doc->createTextNode( $info['Shortd'] )
  );
  $b->appendChild( $shortd );
  
  $longd = $doc->createElement( "Longd" );
  $longd->appendChild(
  $doc->createTextNode( $info['Longd'] )
  );
  $b->appendChild( $longd );
  
  $prijs = $doc->createElement( "Prijs" );
  $prijs->appendChild(
  $doc->createTextNode( $info['Prijs'] )
  );
  $b->appendChild( $prijs );
  
  $r->appendChild( $b );
  }
  
  echo $doc->saveXML();
  $doc->save("info.xml")
?>

The entire code:

<?php
ini_set('display_startup_errors', 1);
ini_set('display_errors', 1);
ini_set('error_reporting', 8191);
ini_set('docref_root', '[URL unfurl="true"]http://www.php.net/');[/URL]
ini_set('date.timezone', 'Europe/Amsterdam');
//echo $_POST;

top_admin('prijzen', $pagina_titel);	
open_db();

//Get the file out of the form that was sended
$uploadedfile = $_FILES['plaatje']['tmp_name'];

$src = imagecreatefromjpeg($uploadedfile);

list($width,$height)=getimagesize($uploadedfile);


//Creates new width and height for the picture
$newwidth=60;
$newheight=80;
$tmp=imagecreatetruecolor($newwidth,$newheight);


imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height);

$original_filename = "../../occasions/fotos_small/".$_FILES['plaatje']['name'];
$new_filename = trim( strtolower( $original_filename ), 'jpg' ) . 'png'; 
 
//preg_match('~/(:<png_file>.+\.png)$~', $new_filename, $matches);
//$naam_plaatje = str_ireplace('.jpg', '.png', $_FILES['plaatje']['name');
$array = explode('/', $new_filename);
$last = end($array);
$sql="INSERT INTO prijzen (Omschrijving, omschrijving1, omschrijving2, dagprijs, foto)
VALUES
('$_POST[artikel]', '$_POST[korte_omschrijving]', '$_POST[uitgebreide_omschrijving]', '$_POST[prijs]', '" . $last . "')";

//echo '<pre>' . print_r($matches, true) . '</pre>';
//echo $sql . "<br />" . "<br />";
mysql_query($sql);

//$filename = "../occasions/fotos_small/". $_FILES[plaatje][name];
imagepng($tmp,$new_filename,9);
//$filename2 = "../occasions/fotos_medium/". $_FILES[plaatje_m][name];

imagedestroy($src);
imagedestroy($tmp); 

//if (isset($_FILES['plaatje'])){
//  writetofolder('../occasions/fotos_small');
//}
//
//if (isset($_FILES['plaatje_m'])){
//  writetofolder2('../occasions/fotos_medium');
//}
//function writetofolder($foldername){
// if (!is_file($_FILES['plaatje']['tmp_name'])) return false;
// $f = copy ($_FILES['plaatje']['tmp_name'], $foldername . '/'.$_FILES['plaatje']['name']);
// return $f;
//}
//function writetofolder2($foldername){
// if (!is_file($_FILES['plaatje_m']['tmp_name'])) return false;
// $f = copy ($_FILES['plaatje_m']['tmp_name'], $foldername . '/'.$_FILES['plaatje_m']['name']);
// return $f;

-------------------------------------
I am a progammer.... no realy.

 

[jpadie]

instead of this

$doc->save("info.xml")

use this

$xml = $doc->saveXML();
file_put_contents('info.txt', $xml, FILE_APPEND | LOCK_EX);
