[SOLVED] headers and readfile

[rondog]

I have a phpfile that is reading different kinds of files that I want to force download. My switch case statements are working and it is downloading them, however, its spitting out all this binary code. Any idea why that is so? I am just trying to force the download. thanks.

<?php
session_start();
if ($_SESSION['approved'] != 'yes') {
header("Location: dlerror.php");
} else {
$filename = $_POST['fname'];
$filename = realpath("8d46y2g1/".$filename);
echo($filename);

$file_extension = strtolower(substr(strrchr($filename,"."),1));

switch ($file_extension) {
	case "pdf": $ctype="application/pdf"; break;
	case "exe": $ctype="application/octet-stream"; break;
	case "zip": $ctype="application/zip"; break;
	case "doc": $ctype="application/msword"; break;
	default: $ctype="application/force-download";
}

if (!file_exists($filename)) {
	die("NO FILE HERE");
}
echo($ctype);
header("Content-Type: $ctype");
header("Content-Disposition: attachment; filename=\"".basename($filename)."\";");
set_time_limit(0);
@readfile("$filename") or die("File not found.");
}
?>

When I made some force-download scripts, I assisted with the script in this tutorial. Make sure you have everything that it has there. I think if you will change your script this way, it will work:

 

<?php
session_start();
if ($_SESSION['approved'] != 'yes') {
header("Location: dlerror.php");
} else {
$filename = $_POST['fname'];
$filename = realpath("8d46y2g1/".$filename);

$file_extension = strtolower(substr(strrchr($filename,"."),1));

switch ($file_extension) {
	case "pdf": $ctype="application/pdf"; break;
	case "exe": $ctype="application/octet-stream"; break;
	case "zip": $ctype="application/zip"; break;
	case "doc": $ctype="application/msword"; break;
	default: $ctype="application/force-download";
}

if (!file_exists($filename)) {
	die("NO FILE HERE");
}

// required for IE, otherwise Content-disposition is ignored
if(ini_get('zlib.output_compression'))
	ini_set('zlib.output_compression', 'Off');
header("Pragma: public"); // required
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false); // required for certain browsers 
header("Content-Type: $ctype");
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize(basename($filename)));
header("Content-Disposition: attachment; filename=\"".basename($filename)."\";");
set_time_limit(0);
@readfile("$filename") or die("File not found.");
}
?>

 

 

Orio.
