php process xml into array - php

Question

I'm tring to process xml (website) into php array.
I have tried the following code which works for everyting in results but i need to get the totalpage which i'm not able to see how I can do this.
function get_content($url)
/// basically opens the page and stores it as a variable. Buggered if I know how it works!
{
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_HEADER, 0);
ob_start();
curl_exec ($ch);
curl_close ($ch);
$string = ob_get_contents();
ob_end_clean();
return $string;
$string = NULL;
$ch = NULL;
$url = NULL;
}
$url = "url";
$content = get_content($url);
$content_x = explode("<result>", $content);
foreach ($content_x as $item)
{
$p1 = strpos($item, '<title>');
$p2 = strpos($item, '</title>');
$l1 = $p2 - $p1;
echo '<br>'.$title = substr($item, $p1, $l1);
}
xml site feed
<?xml version="1.0" encoding="UTF-8"?>
<response version="2">
<totalpage>1005</totalpage>
<results>
<result>

You absolutely should not be using string manipulation to try to parse XML. There are any number of PHP libraries that can do this. I might recommend SimpleXML.
Usage would be:
$xml = simplexml_load_string($content);
$totalpage = $xml->response->totalpage;
