    copied!<p>Given that you have an array that contains varying amounts of objects, how can you access the properties of the last object? I tried to use <code>end($array);</code> but it gives the error: <code>Object of class Post could not be converted to string</code></p> <p>The class is:</p> <pre><code>class Post { private $datafile; public $index; public $subIndex; public $poster; public $title; public $message; public $date; // constructor and some unrelated methods here public function getCommentData($givenIndex) { $comments = null; $data = file($this-&gt;datafile); foreach($data as $row) { list($index, $subIndex, $poster, $message, $date) = explode('|', $row); $this-&gt;index = $subIndex; // SubIndex ties a Comment to a Post (same ID) if($this-&gt;index == $givenIndex) { $comment = new Post(); $comment-&gt;poster = $poster; $comment-&gt;message = $message; $comment-&gt;date = date(DATEFORMAT, strtotime($date)); $comments[] = $comment; } } return $comments; } } </code></pre> <p>Now, I would like to access only the last Comment item's properties, but I'm not sure how it should be done? In a regular array, end() is quick and easy to use, but how about with objects as it doesn't seem to work?</p> <p>Here is an example var_dump:</p> <pre><code>array (size=2) 0 =&gt; object(Post)[4] private 'datafile' =&gt; null public 'index' =&gt; null public 'subIndex' =&gt; null public 'poster' =&gt; string 'Postaaja' (length=8) public 'title' =&gt; null public 'message' =&gt; string 'Kommentti' (length=9) public 'date' =&gt; string '5 Mar 2013 | 23:12' (length=18) 1 =&gt; object(Post)[5] private 'datafile' =&gt; null public 'index' =&gt; null public 'subIndex' =&gt; null public 'poster' =&gt; string 'Toinenkin' (length=9) public 'title' =&gt; null public 'message' =&gt; string 'Lisäkommentti' (length=14) public 'date' =&gt; string '5 Mar 2013 | 23:13' (length=18) </code></pre> <p>Thanks!</p> <p>EDIT: Here's the way I tried to use it:</p> <pre><code>$comments = new Post(FILECOMMENTS); $currentComments = $comments-&gt;getCommentData($i); // $i is the index of current newspost item $newsComments = new Format(); $newsComments-&gt;formatShortComment($currentComments, $i); </code></pre> <p>And the method in the Format class:</p> <pre><code>// This comment is displayed as a short text in the main News view public function formatShortComment($data, $index) {?&gt; &lt;div class="newsComments"&gt; &lt;p class="newsPreviewComment"&gt; &lt;?php $lastItem = end($data); if(!empty($lastItem-&gt;message)) { echo '&lt;i&gt;&amp;quot;',$lastItem-&gt;message,'&amp;quot;&lt;/i&gt; '; echo '-',$lastItem-&gt;poster; } ?&gt;&lt;/p&gt; &amp;raquo; &lt;a href="?page=comments&amp;amp;id=&lt;?php echo $index; ?&gt;"&gt;Show All/Add comments&lt;/a&gt; (&lt;?php echo $commentCount; ?&gt;) &lt;/div&gt;&lt;?php } </code></pre>
