File download

[ToonMariner]

I have this code

 

if	(
strcmp(substr($_SERVER['DOCUMENT_ROOT'],-1,1),'/')	==	0
)
{
include_once($_SERVER['DOCUMENT_ROOT'] . 'config.php');
}
else
{
include_once($_SERVER['DOCUMENT_ROOT'] . '/config.php');
}



$error		=	NULL;
$user		=	$_GET['user'];
$filename	=	$user . $_GET['file'];

//echo $filename;

if	(
ini_get('zlib.output_compression')
)
{
ini_set('zlib.output_compression', 'Off');
}

$file_extension	=	explode('.',$filename);
$pos	=	count($file_extension) - 1;
//echo $pos;
$file_extension	=	$file_extension[$pos];
//echo $file_extension;

if	(
is_null($filename)
) 
{
$erro	=	 "Error: No file path passed to script.";
echo $erro;
exit;
}
/*
else
{
$first_char	=	substr($filename,0,1); 
if	(
	$first_char		==	"/"
	)
{ 
	$filename	=	substr(strtolower($filename), 1); 
}
if	(
	!file_exists($_SERVER['DOCUMENT_ROOT'] . $filename)
	) 
{
	$error 	=	"Error: No such file found.";
	echo $erro;
	exit;
}
}*/


switch	($file_extension)
{
case	"pdf":
	$ctype	=	"application/pdf";
	break;
case	"exe":
case	"mp3":
	$ctype	=	"application/octet-stream";
	break;
case	"zip":
	$ctype	=	"application/zip";
	break;
case	"doc":
	$ctype	=	"application/msword";
	break;
case	"xls":
	$ctype	=	"application/vnd.ms-excel";
	break;
case	"ppt":
	$ctype	=	"application/vnd.ms-powerpoint";
	break;
case	"gif":
	$ctype	=	"image/gif";
	break;
case	"png":
	$ctype	=	"image/png";
	break;
case	"mp3":
	$ctype	=	"audio/mp3";
	break;
case	"mpg":
case	"mpeg":
	$ctype	=	"video/mpeg";
	break;
case	"mp4":
	$ctype	=	"video/mp4";
	break;
case	"jpeg":
case	"jpg":
	$ctype	=	"image/jpg";
	break;
default:
	exit();
}


header('Pragma: public');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Cache-Control: private',false);
header('Content-Type: ' . $ctype);
header('Content-Disposition: attachment; filename="' . basename($filename) . '";' );
header('Content-Transfer-Encoding: binary');
header('Content-Length: ' . filesize($filename));
readfile($filename);
exit();


?>

 

Which I pass the correct parameters through to download a file.

 

The file download is successful BUT when trying to play the file I get this from media player...

 

The file you are attemping to play has an extension (.mp3) that does not match the file format....

 

Can anybody suggest why this is so? I have removed id3 tags from the mp3 files etc etc and still no joy...

This works for me:

<?php
$path = substr($_SERVER['DOCUMENT_ROOT'],-1)=='/' ? $_SERVER['DOCUMENT_ROOT'] : $_SERVER['DOCUMENT_ROOT']."/";
require_once "{$path}config.php";

$error		= null;
$user		= $_GET['user'];
$filename	= $user.$_GET['file'];

if(ini_get('zlib.output_compression'))
{
ini_set('zlib.output_compresion',0);
}

$file_parts = pathinfo($filename);
$file_extension = $file_parts['extension'];

if(empty($filename))
{
die('Error: No file path passed to script.');
}

$mime = array(
	'pdf' => 'application/pdf',
	'exe' => 'application/octet-stream',
	'zip' => 'application/zip',
	'doc' => 'application/msword',
	'xls' => 'application/vnd.ms-excel',
	'ppt' => 'application/vnd.ms-powerpoint',
	'gif' => 'image/gif',
	'png' => 'image/png',
	'mp3' => 'audio/mp3',
	'mpg' => 'video/mpeg',
	'mpeg'=> 'video/mpeg',
	'mp4' => 'video/mp4',
	'jpg' => 'image/jpg',
	'jpeg'=> 'image/jpg',
);

if(key_exists($file_extension,$mime))
{
$ctype = $mime[$file_extension];
}
else {
die();
}

header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); 
header("Content-Type: {$ctype}");
header("Content-Disposition: attachment; filename={$file_parts['basename']}");
header("Content-Description: File Transfer");
header("Content-Transfer-Encoding: binary");
header("Accept-Ranges: bytes");
header("Content-Length: ".filesize($filename));
readfile($filename);
?>

Thanks but no luck - think I may have to put a ticket in on server admin....
