I have a database table that contains numerous PDF blob files. I am attempting to combine all of the files into a single ZIP file that I can download and then print.

Please help!

<?php 
include 'config.php';
include 'connect.php';

$session= $_GET[session];

$query = "
 SELECT $tbl_uploads.username, $tbl_uploads.description, 
        $tbl_uploads.type, $tbl_uploads.size, $tbl_uploads.content,  
        $tbl_members.session
 FROM $tbl_uploads
 LEFT JOIN $tbl_members
 ON $tbl_uploads.username = $tbl_members.username
 WHERE $tbl_members.session= '$session'"; 

$result = mysql_query($query) or die('Error, query failed');

while(list($username, $description, $type, $size, $content) = 
  mysql_fetch_array($result)) 
{ 

header("Content-length: $size");
header("Content-type: $type");
header("Content-Disposition: inline; filename=$username-$description.pdf");
echo $content;
}

$files = array('File 1 from database', 'File 2 from database'); 
$zip = new ZipArchive; 
$zip->open('file.zip', ZipArchive::CREATE); 
foreach ($files as $file) { 
  $zip->addFile($file); 
} 
$zip->close(); 

header('Content-Type: application/zip'); 
header('Content-disposition: attachment; filename=filename.zip'); 
header('Content-Length: ' . filesize($zipfilename)); 
readfile($zipname); 

mysql_close($link);
exit;

?>
