php xpath returns node value as Array

Question

Im using xpath to get values for a cms page,

video?id=blahblah

My PHP Xpath Code is

<?php
$db = simplexml_load_file("data.xml");
$title = $db->xpath("//video[@id=$id]/title");

Im doing this for all values, below is my xml code

<data>
<video id="1">
<title>Test</title>
</video>

I want the title heading to say Test but it says array instead

XPath queries return a sequence of result nodes, not a single one. SimpleXML returns this as an array of SimpleXMLElements (which have reasonable __toString implementations, so you can directly output them in string context).

So if you're sure you will only have a single result, just pick the first item of the array:

$title = $db->xpath("//video[@id=$id]/title")[0];
