How to solve the issue with downloading in PHP? - php

Question

guys.
I am using a local server with laravel framework and trying to download file.
I tried many cases but nothing works for me.
The thing is I get no errors.
Downloading wont`t start but in response I have something like this:
�
���JFIF��;CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 95��C
���}!1AQa"q2���#B��R��$3br�
%&'()*456789:CDEFGHIJSTUVWXYZcdefghijstuvwxyz���������������������������������������������������������������������������
���w!1AQaq"2�B���� #3R�br�
$4�%�&'()*56789:CDEFGHIJSTUVWXYZcdefghijstuvwxyz��������������������������������������������������������������������������?���!�A���I��+�P�sB���i��?�Y�L��iG���B���Ap�����J;���;}ic=F{R�Z��
�$��z�q��~�p8�h�v?A#��;����t�#�Fx��Ǯq�S#<������qS-
That what I used:
tried this way:
$file = 'D:\Server\OpenServer\domains\memo.ru\public\img\avatars\\'.$file_name;
$filePath=$file;
and this:
$file = "http://example.com/img/avatars/1457091259.png";
1.
set_time_limit(0);
$file = #fopen($filePath, 'rb');
while ( !feof($file) ) {
print( #fread($file,1024*8) );
//ob_flush();
flush();
}
2
$handle = fopen($filePath, 'rb');
$buffer = '';
while ( !feof($handle) ) {
$buffer = fread($handle, 4096);
echo $buffer;
ob_flush();
flush();
}
fclose($handle);

header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
//header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);

$real_path = 'D:\Server\OpenServer\domains\example.com\public\img\avatars\\';
$file = "http://example.com/img/avatars/1457091259.png";
$url = 'http://example.com/img/avatars/'.$tmpFileName;
$path = $real_path.$tmpFileName;
$fp = fopen($path, 'w');
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_FILE, $fp);
$data = curl_exec($ch);
curl_close($ch);
fclose($fp);

Answer 1

If you're using Laravel 5 then this would be the most straightforward way:
public function download()
{
$file = base_path(). "public/img/avatars/1457091259.png";
$name = "Human Name For File.jpg";
$headers = ['Content-Type: application/octet-stream'];
return Response::download($file, $name, $headers);
}
Just name sure you have use Response at the top before the class
The application/octet-stream header should force the browser to download the file rather than display it in the browser window.

Answer 2

This should work
header('Content-Type: image/png');
header('Content-disposition: attachment; filename='.$fileName);
echo readfile($file);
die();

Answer 3

I have used the following quite successfully for downloading / sending files - perhaps it will be of use to you?
Call it like:
call_user_func( 'send_file', 'myfile.docx', 'c:/temp/document.docx' );
function send_file( $name, $strPath ) {
if( file_exists( $strPath ) ) {
if( !is_file( $strPath ) or connection_status()!=0 ) { return FALSE; }
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
header("Expires: ".gmdate("D, d M Y H:i:s", mktime(date("H")+2, date("i"), date("s"), date("m"), date("d"), date("Y")))." GMT");
header("Last-Modified: ".gmdate("D, d M Y H:i:s")." GMT");
header("Content-Type: application/octet-stream");
header("Content-Length: ".(string)( filesize( $strPath ) ) );
header("Content-Disposition: inline; filename={$name}");
header("Content-Transfer-Encoding: binary\n");
if( $file = fopen( $strPath, 'rb' ) ) {
while( !feof( $file ) and ( connection_status()==0 ) ) {
print( fread( $file, 1024*8 ) );
flush();
}
fclose( $file );
}
clearstatcache();
return( ( connection_status()==0 ) and !connection_aborted() );
}
}
