php class for converting html to pdf not working

[shane07]

Hello

I have downloaded php class for html to pdf from phpclasses.org. I just tried it but it is not working. The exported pdf is of 0 bytes. Even when I run the program as it is, it is not working. Same problem arise there too.

The class file is as follows:

define ("HKC_USE_ABC",1);
define ("HKC_USE_EASYW",2);

class HTML_TO_PDF
{
	var $html 	= "";
	var $htmlurl= "";
	var $error 	= "";
	var $host	= "";
	var $port	= 80;
	var $url	= "";
	var $_useurl  = "";

	var $saveFile = "";
	var $downloadFile = "";	
	var $_cookie = "";

	function HTML_TO_PDF($html="",$useurl = HKC_USE_ABC)
	{
		$this->html = $html;
		$this->_useurl=$useurl;
	}

	function useURL($useurl)
	{
		$this->_useurl = $useurl;
	}

	function saveFile($file="")
	{
		if(empty($file))
			$this->saveFile = time().".pdf";
		else 
			$this->saveFile =$file;
	}

	function downloadFile($file="")
	{
		if(empty($file))
			$this->downloadFile = time().".pdf";
		else 
			$this->downloadFile =$file;
	}

	function error()
	{
		return  $this->error;
	}

	function convertHTML($html="")
	{
		if(!empty($html))
			$this->html=$html;
		$htmlfile = time().".html";
		$url = "http://".$_SERVER['SERVER_NAME'].dirname($_SERVER['PHP_SELF'])."/".$htmlfile;

		$this->write_file($htmlfile,$this->html);

		$return = $this->convertURL($url);

	}

	function convertURL($url)
	{

		@header("Content-type: application/octet-stream");
		@header("Content-Disposition: attachment; filename=".$this->downloadFile);
		echo $pdfdata;
	}

}

and the file where this class is included is as follows:

require('html_to_pdf.inc.php');
$htmltopdf = new HTML_TO_PDF();

//$htmltopdf->useURL(HKC_USE_EASYW);  // default HKC_USE_ABC other HKC_USE_EASYW
$htmltopdf->saveFile("abc.pdf");
$htmltopdf->downloadFile("abc.pdf");
//$result = $htmltopdf->convertHTML("<b>MY TEST</b>");
$result = $htmltopdf->convertURL("http://test.ultraglobal.info/govazo/");
if($result==false)
	echo $htmltopdf->error();

The abc.pdf file is exported but is of 0 bytes

waiting for ur reply. Thank You.
