Sorry for the noobie question, but how can I convert this PHP code into a working program?
Code:
<?php
/**
* Tubelogix
*/
function fetch_youtube_links($url)
{
$__types = array( 'video/x-flv' => 'FLV', 'video/webm' => 'WEBM', 'video/mp4' => 'MP4', 'video/3gpp' => '3GP');
$url_components = parse_url($url);
if($url_components === false || !isset($url_components['query']))
return false;
$query_vars = array();
parse_str($url_components['query'], $query_vars);
if(!isset($query_vars['v']))
return false;
$id = $query_vars['v'];
$infos_url = 'http://www.youtube.com/get_video_info?video_id='.$id.'&asv=3&el=detailpage&hl=en_US';
$ch = curl_init($infos_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$infos_content = curl_exec($ch);
curl_close($ch);
$infos = array();
parse_str($infos_content, $infos);
if(isset($infos['errorcode']) || !isset($infos['url_encoded_fmt_stream_map']))
return false;
$links = explode(',', $infos['url_encoded_fmt_stream_map']);
if(($number_of_vids = count($links)) === 0)
return false;
$result = array('infos' => array(), 'links' => array());
$result['infos']['video_id'] = isset($infos['video_id']) ? $infos['video_id'] : '';
$result['infos']['title'] = isset($infos['title']) ? $infos['title'] : '';
$result['infos']['length'] = isset($infos['length_seconds']) ? $infos['length_seconds'] : '';
$result['infos']['author'] = isset($infos['author']) ? $infos['author'] : '';
$result['infos']['thumbnail'] = isset($infos['thumbnail_url']) ? $infos['thumbnail_url'] : '';
$result['infos']['img'] = isset($infos['iurlsd']) ? $infos['iurlsd'] : '';
$result['infos']['keywords'] = isset($infos['keywords']) ? explode(',',$infos['keywords']) : '';
$result['infos']['views'] = isset($infos['view_count']) ? $infos['view_count'] : '';
foreach($links as $link)
{
$infos_link = array();
parse_str($link, $infos_link);
if(isset($infos_link['url']) && isset($infos_link['sig']))
{
$url = $infos_link['url'].'&signature='.$infos_link['sig'].'&title='.$result['infos']['title'];
$type = '';
$quality = isset($infos_link['quality']) ? $infos_link['quality'] : '';
if(isset($infos_link['type']))
{
$data_type = explode(';', $infos_link['type']);
$mime_type = trim($data_type[0]);
if(array_key_exists($mime_type, $__types))
$type = $__types[$mime_type];
}
//Optional : fetch the size of the video
$head = get_headers($infos_link['url'].'&signature='.$infos_link['sig']);
$size = '';
foreach($head as $header)
if(strpos(trim($header), 'Content-Length:') === 0)
{
$size = trim(substr($header, 15));
break;
}
$result['links'][] = array('url' => $url, 'type' => $type, 'quality' => $quality, 'size' => $size);
}
}
return $result;
}
$url = 'http://www.youtube.com/watch?v=Rgox84KE7iY';
var_dump(fetch_youtube_links($url));
