Is there a possible PHP memory leak with this XML code?

[YoungOBi]

Is there a possible memory leak with the code below? We have a website running on an Apache server with PHP v5.3.3 and this code is being criticized as possibly having a memory leak. Was hoping another set of eyes looking at this would help spot an issue.\[code\]<?php// set feed URL$feedURL = 'http://gdata.youtube.com/feeds/api/users/UFDeptHousing/uploads';// read feed into SimpleXML object$sxml = simplexml_load_file($feedURL);?><?php// iterate over entries in feed $i = 0;foreach ($sxml->entry as $entry) { if($i < 4) { // get nodes in media: namespace for media information $media = $entry->children('http://search.yahoo.com/mrss/'); // get video player URL $attrs = $media->group->player->attributes(); $watch = $attrs['url']; // get video thumbnail $attrs = $media->group->thumbnail[1]->attributes(); $thumbnail = $attrs['url']; // get <yt:duration> node for video length $yt = $media->children('http://gdata.youtube.com/schemas/2007'); $attrs = $yt->duration->attributes(); $length = $attrs['seconds']; // get <yt:stats> node for viewer statistics $yt = $entry->children('http://gdata.youtube.com/schemas/2007'); $attrs = $yt->statistics->attributes(); $viewCount = $attrs['viewCount']; // get <gd:rating> node for video ratings $gd = $entry->children('http://schemas.google.com/g/2005'); if ($gd->rating) { $attrs = $gd->rating->attributes(); $rating = $attrs['average']; } else { $rating = 0; } ?> <tr> <td width="95"> <span class="thumbnail"><a href="http://stackoverflow.com/questions/12753287/<?php echo $watch; ?>"><img src="http://stackoverflow.com/questions/12753287/<?php echo $thumbnail;?>" width="85" height="48" alt="<?php $varlength = strlen($media->group->title); if ($varlength > 30) { echo substr($media->group->title,0,30)."..."; }else { echo $media->group->title; } ?>" /></a></span> </td> <td width="130"> <span class="title"><a href="http://stackoverflow.com/questions/12753287/<?php echo $watch; ?>"> <?php $varlength = strlen($media->group->title); if ($varlength > 30) { echo substr($media->group->title,0,30)."..."; }else { echo $media->group->title; } ?> </a></span> <span class="length">Length: <?php printf('%0.2f', $length/60); ?></span> </td> </tr><?php } $i++;}?>\[/code\]
