Me enseñan a usar cUrl

[andresdzphp]

Código PHP:

<?php
 
$url = 'http://198.50.101.130:9830/played.html';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; 
        rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');
$str = curl_exec($curl);
curl_close($curl);
 
$doc = new DOMDocument();
libxml_use_internal_errors(true);
$doc->loadHTML($str);
$xpath = new DOMXPath($doc);
$rows = $xpath->query('//table[position()=2]/tr[position()>1]');
 
foreach ($rows as $row) {
    $td = $row->getElementsByTagName('td');
    echo "Hora: {$td->item(0)->nodeValue} <br />";
    echo "Canción: {$td->item(1)->nodeValue} <hr />";
}
