取一个现有的数组，并按值对其进行制动 - Take an existing array and brake it up by value

我有一个simplepie提要，它从加载到关联数组中的每个URL中吐出多个提要。

此关联数组用于使用值按字母顺序对数组进行排序。

我试图使用相同的值排序，并将所有具有相同URL或值的数组放在一起，这样当foreach循环运行时，我会为每个URL获得一个div，其中包含当天的所有来自该URL的提要

<?php
require_once('php/autoloader.php');

$feed = new SimplePie(); // Create a new instance of SimplePie
// Load the feeds
$urls = array(

也许你可以使用这个：

$feed = new SimplePie();
$feed->set_feed_url('http://myfirstfeed','http://mysecondfeed');
foreach( $feed->get_items() as $k => $item ) {
   echo "<div id='".$k.'">";
   echo $item->get_permalink();
   echo $title   = $item->get_title();
   echo $item->get_date('j M Y, g:i a');
   echo $item->get_content();
   echo "</div>";
}
