Re: [Pro. PHP Dev.] Download file from server to client machine

[Robert Gonzalez]

You either need to echo the file_get_contents call or use readfile, which kinda does the same thing.

Hi all,
can anyone tell me the solution to download file from server to the local machine, i have used header function to do this, but right now only the file is creating at the destination drive but the actual data from the server file is not getting there in client machine's file,
 

$path = $_GET['download_file'];
$mm_type="application/octet-stream";
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Type: " . $mm_type);
header("Content-Length: " .(string)(filesize($path)) );
header('Content-Disposition: attachment; filename="'.basename($path).'"');
header("Content-Transfer-Encoding: binary\n");
file_get_contents($path); // outputs the content of the file
exit();

hi priyanka, perhaps your server needs to be nudged into handling the
correct mime type?

I've encountered such server quirks before, for example a MS Excel
spreadsheet would not download, so had to force the set mime type on
Apache...it might be as simple as adding this to your .htaccess
file:
AddType application/pdf .pdf

let's see, ah here are examples of forcing PDF:

goodluck!

Try below

<?php
/*
Make sure is your file readable
*/
$path = "/var/www/Ebook.pdf";
$mm_type="application/octet-stream";
$fsize = filesize($path);

header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");

header("Cache-Control: private",false);
header("Content-Type: application/pdf");
header("Content-Length: " .$fsize);

header('Content-Disposition: attachment; filename="'.basename($path).'"');
header("Content-Transfer-Encoding: binary\n");

/*
require to flush new line or extra space while we are reading file otherwise pdf file may get corrupt
*/
ob_clean();
flush();
/*
 Use for large file
*/
$handle = fopen("$path", "rb");
$contents = '';
while (!feof($handle)) {
  $contents .= fread($handle, 8192);
}
print $contents;
fclose($handle);
exit();?>

Hi priyanka,

    Try readfile($path) instead of file_get_contents($path)

[neeraj]

ok here is the solution change the last two lines of your code to

$filedata = file_get_contents($path); // outputs the content of the
file
exit($filedata);

[vishal bhandare]

Hi priyanka,

Have you tried my code?
It is tested and it works. You should at least try it.

<?php
/*
Make sure is your file readable
*/
$path = "/var/www/Ebook.pdf";
$mm_type="application/octet-

stream";
$fsize = filesize($path);

header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");

header("Cache-Control: private",false);
header("Content-Type: application/pdf");
header("Content-Length: " .$fsize);

header('Content-Disposition: attachment; filename="'.basename($path).'"');
header("Content-Transfer-Encoding: binary\n");

/*
require to flush new line or extra space while we are reading file otherwise pdf file may get corrupt
*/
ob_clean();
flush();
/*
 Use for large file
*/
$handle = fopen("$path", "rb");
$contents = '';
while (!feof($handle)) {
  $contents .= fread($handle, 8192);
}
print $contents;
fclose($handle);
exit();?>

it surely means file that you are downloading don't have proper permission to read. Please check the permission of file.
