Sort Foreach XML

[DaemonProjects]

Hello,

I'm trying to sort the foreach code below but using sort() doesn't work, using the code below how do I sort a xml file from the bottom up and not the top bottom?

D

<?
  $doc = new DOMDocument();
  $doc->load( 'profiles/'.$_COOKIE["SN"][0].'/wall.xml' );

  $books = $doc->getElementsByTagName( "write" );
  sort($doc);
  $ii = 0;
  foreach( $books as $book) {
  	$ii = $ii+1;
	if ($ii == 10) {
		exit;
	}
  $profile_img = $book->getElementsByTagName( "profileimg" );
  $profile_img = $profile_img->item(0)->nodeValue;

  $desc = $book->getElementsByTagName( "desc" );
  $desc = $desc->item(0)->nodeValue;

  $name = $book->getElementsByTagName( "name" );
  $name = $name->item(0)->nodeValue;

  $date = $book->getElementsByTagName( "date" );
  $date = $date->item(0)->nodeValue;

?>
<div class="transOFF" onmouseover="this.className='transON'" onmouseout="this.className='transOFF'">
<table width="100%" border="0" cellpadding="0" cellspacing="0" background="images/back2.jpg" class="newsbrdr">
  <tr>
    <td align="center" valign="top" bgcolor="#330000"><table width="65" border="0" cellspacing="0" cellpadding="0">
      <tr>
        <td align="center" class="name"><? echo $name; ?></td>
      </tr>
      <tr>
        <td align="center" class="spacer">&nbsp;</td>
      </tr>
      <tr>
        <td align="center"><? if ($profile_img == "") { ?><img src="images/59168-1.png" width="65" height="65" /><? } else { ?><img src="<? echo $profile_img; ?>" width="65" height="65" /> <? } ?></td>
      </tr>
      <tr>
        <td align="center" class="spacer">&nbsp;</td>
      </tr>
    </table>
    </td>
    <td width="100%" align="left" valign="top"><table width="100%" border="0" cellspacing="0" cellpadding="0">
      <tr>
        <td align="right" bgcolor="#330000" class="date"><? echo $date; ?> &nbsp;&nbsp;</td>
        </tr>
      <tr>
        <td align="left" valign="top"><table width="100%" border="0" cellspacing="6" cellpadding="0">
          <tr>
            <td class="newstxt"><? echo $desc; ?></td>
          </tr>
        </table>          </td>
        </tr>
    </table></td>
  </tr>
</table>
</div>
<?
}
?>

You have sort($doc);, but I think you meant sort($book);, perhaps? If your intent is simply reverse the array, you could use array_reverse($book), instead.

I get this Warning:

Warning: array_reverse() [function.array-reverse]: The argument should be an array in C:\wamp\www\SN\wall.php on line 50

using:

$doc = new DOMDocument();
  $doc->load( 'profiles/'.$_COOKIE["SN"][0].'/wall.xml' );

  $books = $doc->getElementsByTagName( "write" );
  array_reverse($books);
  $ii = 0;
  foreach( $books as $book) {

also tried:
foreach( $books as array_reverse($book)) {

Still no luck

[NogDog]

getElementsByTagName() returns an object, not an array. Perhaps you could do something like:

$books = array();
foreach($doc->getElementsByTagName( "write" ) as $book)
{
   $books[] = $book;
}
array_reverse($books);

doc is a class not an array?????

these functions only work on arrays

(i might be wrong on the array/class statement but i am sure about the second line...)

[NogDog]

In PHP 5, you can use foreach on an object. (Other array functions probably will not work though.)
