Help echoing array from php function - php

Question

Alright I am still learning my functions in php but this particular piece of code has me stuck. Credit goes to http://www.barattalo.it/2010/08/29/php-bot-to-get-wikipedia-definitions/ for the wikipedia query segment. I thought this looked interesting and am trying to use the code provided to echo data from the function. This is what I have:
<?php
function wikidefinition($s) {
$url = "http://wikipedia.org/w/api.php?action=opensearch&search=".urlencode($s)."&format=xml&limit=1";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HTTPGET, TRUE);
curl_setopt($ch, CURLOPT_POST, FALSE);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_NOBODY, FALSE);
curl_setopt($ch, CURLOPT_VERBOSE, FALSE);
curl_setopt($ch, CURLOPT_REFERER, "");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_MAXREDIRS, 4);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.1; he; rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8");
$page = curl_exec($ch);
$xml = simplexml_load_string($page);
if((string)$xml->Section->Item->Description) {
return array((string)$xml->Section->Item->Text, (string)$xml->Section->Item->Description, (string)$xml->Section->Item->Url);
} else {
return "blank";
}
}
$define = wikidefinition("test");
echo $define;
?>
however this simply echos "array"
I know the code is getting to the if/else statement because if you change the input in "$define = wikidefinition("test");" to some random key combination such as "qoigenqnge" it will echo "blank" I cannot figure out why it is only echoing "array" instead of the data inside the array. Probably something stupid, but I have been reading up on arrays for a while and cant find any info. Any help will be great thanks!

Have you tried:
print_r($define);
instead of echo ?
