wordpress - Stripping out the limit in this php code -

i found code displaying wordpress posts on page rss feed. has limit display 5 posts.

<?php     $rss = new domdocument();     $rss->load('http://wordpress.org/news/feed/');     $feed = array();     foreach ($rss->getelementsbytagname('item') $node) {         $item = array (              'title' => $node->getelementsbytagname('title')->item(0)->nodevalue,             'desc' => $node->getelementsbytagname('description')->item(0)->nodevalue,             'link' => $node->getelementsbytagname('link')->item(0)->nodevalue,             'date' => $node->getelementsbytagname('pubdate')->item(0)->nodevalue,             );         array_push($feed, $item);     }     $limit = 5;     for($x=0;$x<$limit;$x++) {         $title = str_replace(' & ', ' &amp; ', $feed[$x]['title']);         $link = $feed[$x]['link'];         $description = $feed[$x]['desc'];         $date = date('l f d, y', strtotime($feed[$x]['date']));         echo '<p><strong><a href="'.$link.'" title="'.$title.'">'.$title.'</a></strong><br />';         echo '<small><em>posted on '.$date.'</em></small></p>';         echo '<p>'.$description.'</p>';     } ?> 

i increase $limit "50" example if have less 50 posts show me error.

my guess strip out these lines seems stop script functioning:

$limit = 5; for($x=0;$x<$limit;$x++) 

this should do. limit items contained in feed.

$limit = count($feed); 

i wrap in if ensure has items.

$limit = count($feed); if ($limit > 0) {     for($x=0;$x<$limit;$x++) {         $title = str_replace(' & ', ' &amp; ', $feed[$x]['title']);         $link = $feed[$x]['link'];         $description = $feed[$x]['desc'];         $date = date('l f d, y', strtotime($feed[$x]['date']));         echo '<p><strong><a href="'.$link.'" title="'.$title.'">'.$title.'</a></strong><br />';         echo '<small><em>posted on '.$date.'</em></small></p>';         echo '<p>'.$description.'</p>';     } }
