PHP - Echo key value of the array items
<p>I need to echo the key value of an array.</p>

<p>This is how im outputting my array:</p>

<pre><code>foreach($xml-&gt;channel-&gt;item as $item) {
  $item-&gt;title
}
</code></pre>

<p>I've tried adding:</p>

<pre><code>foreach($xml-&gt;channel-&gt;item as $key =&gt; $item)
</code></pre>

<p>But the value I echo just comes out as: <code>item</code></p>

<p>Any ideas?</p>

<p>Var Dump of item results:</p>

<pre><code>var_dump($xml-&gt;channel-&gt;item);

    object(SimpleXMLElement)#4 (5) { 
["title"]=&gt;  string(33) "BA and union agree to end dispute" 
["description"]=&gt;  string(118) "British Airways and the Unite union reach an agreement which could end the long-running dispute between the two sides." 
["link"]=&gt;  string(61) "http://www.bbc.co.uk/go/rss/int/news/-/news/business-13373638" 
["guid"]=&gt;  string(43) "http://www.bbc.co.uk/news/business-13373638" 
["pubDate"]=&gt;  string(29) "Thu, 12 May 2011 12:33:38 GMT" 
} 
</code></pre>
