Executable delivery

[alph4]

Hey everyone! I'm having trouble with reading up an executable and printing it (along with header data of course) to the browser to deliver it. I get a very very small filesize difference using fread(). I checked the original and downloaded files in a binary hex editor and it seems that the same sequence of a word of data is being written to any file I read from and print to the browser. I tested these with text files also and it seems to happen in the ascii form of a few tabs and a new line. I deleted them in the editor and the EXE runs fine. I dont have any echos that would cause this to my knowledge but I can't find out where else they would be coming from. Any ideas? code below.

 

	function buildDownload($filepath){

		$fsize = filesize($filepath);
		$fref = fopen($filepath, "r");
		$bufsize = 8192;

		header('Content-type: application/octet-stream');
		header('Content-Disposition: attachment; filename="test.txt"');

		while(!feof($fref)){
			$fdata = fread($fref, $bufsize);
			print($fdata);
		}
		return true;


}

That will help you, don't use the fopen stuff. That is what readfile was intended for.

Ok I changed my code to the following but I still get the same bytes written:

function buildDownload($filepath){

		$fsize = filesize($filepath);

		header('Content-type: application/octet-stream');
		header('Content-Disposition: attachment; filename="test.exe"');

		readfile($filepath);
		return true;


}

 

I don't know whats adding the bytes...

In addition, I have determined that the reason its coming out bad is because it is not transferring with binary. I added the mime header line:

 

header("Content-Transfer-Encoding: binary");

 

to fix the problem but I still retain the same results. Anyone see anything wrong with this?
