[SOLVED] Please help URGENT - ZIP file download problem using PHP 5.2.5

[kra1978]

Hello Everyone,

 

I have a site where I can create .zip file using PHP programming on the server. It is working fine. On Server, PHP 5.2.3 is installed. It is working fine for last 6-7 months.

 

Yesterday I needed to switch the site from existing to server to new dedicated server. New server has PHP 5.2.5

 

Now, I can create zip file on the new server without any problem. But when I try to download it form the website, it starts downloading and suddenly shows that download is completed and when I try to unzip file then it is giving error message that file is corrupted/damaged. Yes, it is really corrupted because it's size (KB) is only 5-10% of actual file size.

 

I am using following code for downloading .zip file.

=====================================

$str_filename="";

$str_filepath="";

$str_ext="";

 

$str_filename=trim($rs_download_file->fields("photosetfilename"));

$str_filepath=trim($UPLOAD_ZIPFILE_PATH.$str_filename);

header("Content-Type:application/octet-stream");

header("Content-Disposition:attachment;filename=".$str_filename);

$fp=fopen($str_filepath,'rb');

header("Content-Length:".filesize($str_filepath));

fpassthru($fp);

exit();

=====================================

 

Please help me as soon as possible because I am in real trouble.

 

Thanks in advance,

KRA

All you need to do is look at your old php.ini file settings and cross match with your new settings........

 

your code works so there a setting not set correctly in ur new php.ini file...

[kra1978]

I checked all settings and they are same except one.

 

output_buffering

 

In old server, it is set output_buffering=4096 and in new server it is set output_buffering=no value

 

Please let me know whether this may be problem

 

Thanks again,

first of all check the zip file is being created correctly and you can download via ftp without problems..

 

if possible is thier a link we can try (to view header data etc)

[kra1978]

Yes,

 

There is .zip file created successfully on the server and I also downloaded it using FTP and then unzip...it is working!!!

 

Dedicated Server Providers are saying that you need to change the script. I am not sure whether PHP 5.2.3  and PHP 5.2.5 can have different scripts to download .zip file from the website.

 

 

Please advice,

theirs nothing in that code thats would be affect from the minor version upgrade.

 

humm try this

<?php
   $str_filename="";
   $str_filepath="";
   $str_ext="";
   
   $str_filename=trim($rs_download_file->fields("photosetfilename"));   
   $str_filepath=trim($UPLOAD_ZIPFILE_PATH.$str_filename);
   header("Content-Type:application/octet-stream");
   header("Content-Disposition:attachment;filename=".$str_filename);
//LITTLE TEST
if(!file_exists($str_filepath))
{
die("Bad file path~".$str_filepath);
}
//END
   $fp=fopen($str_filepath,'rb');
   header("Content-Length:".filesize($str_filepath));
   fpassthru($fp);
   exit();
?>

The code you provided is not working. The file is downloaded only 152 KB each time instead of original 1.85 MB file size.

 

I found following code from the internet. Please advice whether it can be helpful or not.

 

==========================

$str_filename="";

$str_filepath="";

$str_ext="";

 

$str_filename=trim($rs_download_file->fields("photosetfilename"));

$str_filepath=trim($UPLOAD_ZIPFILE_PATH.$str_filename);

// $str_ext=getextension($str_filename);

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: application/force-download");

header("Content-Type: application/octet-stream", FALSE);

header("Content-Type: application/download", FALSE);

// header("Content-Type:application/octet-stream");

header("Content-Disposition:attachment;filename=".$str_filename);

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

$fp=fopen($str_filepath,'rb');

header("Content-Length:".filesize($str_filepath));

fpassthru($fp);

exit();

 

==========================

[MadTechie]

can you post the 152 KB file (attached it). i have an idea

[kra1978]

Ok. I have attached the 152 KB file here.

 

Thanks,

KRA

Okay well its a valid zip file, with the index of 2 files

photo_1.jpg

photo_2.jpg

but its truncated (only has the first part of the file)..

 

try this revised version

 

<?php
$str_filename="";
$str_filepath="";
$str_ext="";
   
$str_filename=trim($rs_download_file->fields("photosetfilename"));   
$str_filepath=trim($UPLOAD_ZIPFILE_PATH.$str_filename);

header("Pragma: public");
header("Expires: 0"); // set expiration time
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Disposition: attachment; filename=".basename($str_filename));
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($str_filepath));
readfile($str_filename);
exit();
#$fp=fopen($str_filepath,'rb');
#fpassthru($fp);
?>

[kra1978]

I have one thing to ask...Should I add any MIME types on the server for the code you just provided?

 

Please advice.

KRA

 

[MadTechie]

no need, the code should run fine as it,

 

as a note

readfile($str_filename);

uses more memory but thats not the issule at the moment.

[kra1978]

Ok, I tried the code and now it is downloading file of only 1 KB.

 

Also I found following link. Can you please advice that whether it may be the issue?

 

They are saying that it is the bug in PHP 5.2.5....please let me know.

try this just posted to me from a friend that got the same setup as you........

<?php

$filename = $_GET['file'];

// required for IE, otherwise Content-disposition is ignored
if(ini_get('zlib.output_compression'))
  ini_set('zlib.output_compression', 'Off');

// addition by Jorg Weske
$file_extension = strtolower(substr(strrchr($filename,"."),1));

if( $filename == "" ) 
{
  echo "<html><title>eLouai's Download Script</title><body>ERROR: download file NOT SPECIFIED. USE force-download.php?file=filepath</body></html>";
  exit;
} elseif ( ! file_exists( $filename ) ) 
{
  echo "<html><title>eLouai's Download Script</title><body>ERROR: File not found. USE force-download.php?file=filepath</body></html>";
  exit;
};
switch( $file_extension )
{
  case "pdf": $ctype="application/pdf"; break;
  case "exe": $ctype="application/octet-stream"; break;
  case "zip": $ctype="application/zip"; break;

}

header("Content-Type: $ctype");
// change, added quotes to allow spaces in filenames, by Rajkumar Singh
header("Content-Disposition: attachment; filename=\"".basename($filename)."\";" );
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($filename));
readfile("$filename");
exit();

?>

http://www.php.net/downloads.php

in 5.2.1 their was a bug with the zip creation (thats why i asked about it)
