In PHP, what are some strategies for randomly selecting and displaying a single entry from a large set of XML data on a webpage?

When dealing with a large set of XML data in PHP, one strategy for randomly selecting and displaying a single entry on a webpage is to parse the XML data into an array, generate a random index within the array, and then display the entry at that index on the webpage. 

<?php
// Load XML data from a file
$xml = simplexml_load_file('data.xml');

// Convert XML data to an array
$json = json_encode($xml);
$array = json_decode($json, true);

// Generate a random index within the array
$randomIndex = array_rand($array);

// Display the randomly selected entry on the webpage
echo $array[$randomIndex]['entry'];
?>
