Image downloading is not working. it read directly - php

Image downloading isn't working. It read directly not downloading.
if($_REQUEST['image'] == true){
$URl = $post->guid;
echo $URl;
header("Content-Type: image/png");
header('Content-Description: File Transfer');
header("Cache-Control: no-cache, validated");
header('Content-Type: application/octet-stream');
header("Content-Disposition: attachment; filename=\"".basename($URl)."\"");
header('Content-Transfer-Encoding: binary');
var_dump(readfile($URl));
die;
}

Try this header format,
header("Content-type: application/octet-stream");
header("Content-Length: " . filesize($filename));
header("Content-Disposition: attachment; filename=$filename");
header('Content-Transfer-Encoding: binary');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
fpassthru($fp);

If you want to deliver a ZIP file then you need to use also the correct MIME content type!
$filename = "xml_invoice.zip"
$file = "C:\wamp64\www\mb\inc\tmp\liberty\{$filename}";
header("Content-type: application/zip");
header("Content-Disposition: attachment; filename={$filename}");
header("Content-length: " . filesize($file));
header("Pragma: no-cache");
header("Expires: 0");
readfile($file);
try this: give path to your zip file.
$filepath = "/path/to/some_file.zip";
$file_name = basename($filepath);
header("Content-Type: application/zip");
header("Content-Disposition: attachment; filename=$file_name");
header("Content-Length: " . filesize($filepath));
readfile($filepath);
exit;

Downloaded file save with 0kb and damaged

I have a problem with download script
when I download any file it is save with 0kb.
Any ideas? Here is my PHP script
<?php
$file = $_GET['fname'];
$fullpath = get_bloginfo('template_url')."/application/display/1358947404.pdf";
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($fullpath));
header('Expires: 0');
header('Cache-Control: must-revalidate');
ob_clean();
flush();
readfile($fullpath);
?>
Please add content-length header as well .
Please try this:-
<?php
$file = $_GET['fname'];
$fullpath = get_bloginfo('template_url')."/application/display/1358947404.pdf";
$headers = get_headers($fullpath, 1);// use file absolute path here
$fsize = $headers['Content-Length'];
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($fullpath));
header('Expires: 0');
header('Cache-Control: must-revalidate');
header("Content-Length: " . $fsize);
ob_clean();
flush();
readfile($fullpath);
?>
Try below code hope it will help you.
I have tested this in my localhost.
$file = $_GET['fname'];
$fullpath = get_bloginfo('template_url')."/application/display/1358947404.pdf";
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($fullpath));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($fullpath));
ob_clean();
flush();
readfile($fullpath);

PHP force header download not working on zip files

I have a document download site where I track files downloaded.
My problem is getting zip files to download through the script I am using. Every other file gets forced to download apart from zip files. When a zip file is pushed it just goes to the download.php page where the script is with no file being pushed out.
ob_start();
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
exit;
Here is a code snippet that works for me:
if (strstr($_SERVER['HTTP_USER_AGENT'], "MSIE")) {
header('Content-Type: "application/octet-stream"');
header('Content-Disposition: attachment; filename="'.basename($file_url).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header("Content-Transfer-Encoding: binary");
header('Pragma: public');
header("Content-Length: ".filesize($file_url));
} else {
header('Content-Type: "application/octet-stream"');
header('Content-Disposition: attachment; filename="'.basename($file_url).'"');
header("Content-Transfer-Encoding: binary");
header('Expires: 0');
header('Pragma: no-cache');
header("Content-Length: ".filesize($file_url));
}
readfile($file_url);
Had similar problem, this quotes helped that time:
header('Content-Disposition: attachment; filename="'.basename($file).'"');
I was not using the base_name for the content disposition and length, I had the full path instead. Using base_name worked for me.

How can the image and pdf files be made downloadable

Generally, browsers show the image and pdf files without embedding them in html. I need some codes to make these files not to show in the browsers but make them downloadable like doc files.
Please help me out with this.
This isn't up to you, it is up to the browser.
However, you can make a suggestion as to what to do with it by setting the content-disposition header...
header("Content-Disposition: attachment; filename=\"yourfilename.pdf\"");
Read the doc on the header() function: http://php.net/manual/en/function.header.php
In case this isn't clear... this is for whatever resource is returned by the PHP document. You may need a readfile() in there to do what you are trying to do.
Set a couple of headers:
$filename = ...;
$mime_type = ...; //whichever applicable MIME type
header('Pragma: public');
header('Expires: 0');
header("Content-Disposition: attachment; filename=\"$filename\"");
header("Content-Type: $mime_type");
header('Content-Length: ' . filesize($filename));
readfile($filename);
<?php
header('Content-disposition: attachment; filename=myfile.pdf');
header('Content-type: application/pdf');
readfile('myfile.pdf');
?>
You want to send a content type header to make the browser download the file.
If you aren't' generating it dynamically, you will need to read it off the disk first.
$fullPath = "/path/to/file/on/server.pdf";
$fsize = filesize($fullPath);
$content = file_get_contents($fullPath);
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/pdf");
header("Content-Disposition: attachment; filename=\"".basename($fullPath)."\";" );
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".$fsize);
echo $content;
try this one :
$file = 'youfile.fileextention';
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
exit;
