Getting Flash Media Encoder xml Profile using php - youtube-api

Question

I would like to ask about the xml file that is generated after creating a new broadcast on youtube, I need to get this file using PHP without the need to be logged in to youtube,
I already did something like
public function cURLcheckBasicFunctions()
{
if( !function_exists("curl_init") &&
!function_exists("curl_setopt") &&
!function_exists("curl_exec") &&
!function_exists("curl_close") ) return false;
else return true;
}
/*
* Returns string status information.
* Can be changed to int or bool return types.
*/
public function cURLdownload($url, $file)
{
if( !$this->cURLcheckBasicFunctions() ) return "UNAVAILABLE: cURL Basic Functions";
$ch = curl_init();
if($ch)
{
$fp = fopen($file, "w");
if($fp)
{
if( !curl_setopt($ch, CURLOPT_URL, $url) )
{
fclose($fp); // to match fopen()
curl_close($ch); // to match curl_init()
return "FAIL: curl_setopt(CURLOPT_URL)";
}
if( !curl_setopt($ch, CURLOPT_FILE, $fp) ) return "FAIL: curl_setopt(CURLOPT_FILE)";
if( !curl_setopt($ch, CURLOPT_HEADER, 0) ) return "FAIL: curl_setopt(CURLOPT_HEADER)";
if( !curl_exec($ch) ) return "FAIL: curl_exec()";
curl_close($ch);
fclose($fp);
return "SUCCESS: $file [$url]";
}
else return "FAIL: fopen()";
}
else return "FAIL: curl_init()";
}
public function testXmlFile(){
$xml= 'https://www.youtube.com/livestreaming?source=primary&itag=33&v=CtAsVo0Mug0&action_fmle_profile=1';
echo $this->cURLdownload($xml, "test.xml");
}
but this always returns empty file , but if i took the URl and past it in the browser while logged in to youtube the file downloads ok

As no one has tried to answer my question , i took the frustrating path and made an xml template for what youtube might generate and inserted the information directly by using smiple_xml
$xml = new simple_xml_ext("youtube_template.xml",false,true);
$name = "";
$width = "";
$height = "";
$datarate = "";
$outputsize = "";
//getting the stream from youtube api and replacing it in the document
$stream = "<![CDATA[".$streamName."]]>";
switch ($broadcast_quality) {
case "1080p":
$name = "YouTube (1080p Stream)";
$xml->children()->preset->name = $name;
$width = "1920";
$xml->children()->capture->video->size->width = $width;
$height = "1080";
$xml->children()->capture->video->size->height = $height;
$datarate = "6000";
$xml->children()->encode->video->datarate = $datarate;
$outputsize = "1920x1080";
$xml->children()->encode->video->outputsize = $outputsize;
break;
case "720p":
$name = "YouTube (720p Stream)";
$xml->children()->preset->name = $name;
$width = "1280";
$xml->children()->capture->video->size->width = $width;
$height = "720";
$xml->children()->capture->video->size->height = $height;
$datarate = "4000";
$xml->children()->encode->video->datarate = $datarate;
$outputsize = "1280x720";
$xml->children()->encode->video->outputsize = $outputsize;
break;
case "480p":
$name = "YouTube (480p Stream)";
$xml->children()->preset->name = $name;
$width = "854";
$xml->children()->capture->video->size->width = $width;
$height = "480";
$xml->children()->capture->video->size->height = $height;
$datarate = "2000";
$xml->children()->encode->video->datarate = $datarate;
$outputsize = "854x480";
$xml->children()->encode->video->outputsize = $outputsize;
break;
case "360p":
$name = "YouTube (360p Stream)";
$xml->children()->preset->name = $name;
$width = "640";
$xml->children()->capture->video->size->width = $width;
$height = "360";
$xml->children()->capture->video->size->height = $height;
$datarate = "1000";
$xml->children()->encode->video->datarate = $datarate;
$outputsize = "640x360";
$xml->children()->encode->video->outputsize = $outputsize;
break;
case "240p":
$name = "YouTube (240p Stream)";
$xml->children()->preset->name = $name;
$width = "426";
$xml->children()->capture->video->size->width = $width;
$height = "240";
$xml->children()->capture->video->size->height = $height;
$datarate = "500";
$xml->children()->encode->video->datarate = $datarate;
$outputsize = "426x240";
$xml->children()->encode->video->outputsize = $outputsize;
break;
default:
return false;
break;
}
$xml->children()->output->rtmp->stream = null;
$xml->children()->output->rtmp->stream->add_cdata($streamName);
$xml->saveXML("xml_file_path.xml");
