Everytime I use the code below to stream an image file to me the file comes back as corrupt. The image file most certainly is not corrupt though and is fine when I open it through my ftp. Am I missing something?
$fileTry = imagecreatefromstring(file_get_contents($file_path));
if($fileTry === false)
{
die('no file');
}
else
{
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file_path));
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file_path));
readfile($file_path);
exit;
}

Good morning,
I'm working on serving a zip file through the PHP headers, which downloads, but every time I try to extract it shows that the zip is corrupt... I need a 2nd pair of eyes to look over this... what am I missing? Thank you so much!
$file_download = 'example';
if (isset($file_download)) {
$file = 'path/to/file/'.$file_download.'.zip';
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.basename($file).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
} else {
echo 'File does not exist!';
}
}
I have a code:
$name = "jeffrey.epub"; //for naming only
$file = "test/cover/cabang.epub"; //the real file to be downloaded
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.basename($name).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
but upon having the download file, it came out corrupted.i also change the header('Content-Type: application/octet-stream'); to header('Content-Type: application/epub+zip'); but still it was corrupted, i was wondering what is the problem that the file is being corrupted
When I try to download a file, it downloads but without content, i.e., its size is 0 bytes.
I am using this code, what I am doing wrong?
$fullPath = "/home/yakar/www/files/gpx/".$file;
if (file_exists($fullPath)) {
// setting headers
header('Content-Description: File Transfer');
header('Content-Type: '.$type);
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);
exit;
} else {
die('File does not exist');
}
I am using the following code, to access a file which exists
$file = 'monkey.gif';
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
}
It downloads fine, but when opening the image viewer is refusing to open stating its not a gif file. Is
I think you should change the Content-Type to 'image/gif'
I found that there was a print elsewhere in the code so when it was forcing the download it was corrupted. Removing the print worked.
I have created a beginner program to forcefully download file from unix box to windows through browser, it is not throwing any error but shows nothing on browser just a blank page.
PHP version- 5.2.13
Apache-2.0
Unix Box- HP-UX 11.11 (old version latest is 11.31)
local PC- windows XP Prof.
Browser- IE 7, Mozilla.
Below is my code (this code resides on unix box):
<?php
ob_start();
$file = '/opt/hpws/apache/htdocs/barn/file2';
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream;charset=utf-8');
header('Content-Disposition: attachment; filename=$file');
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
}
?>
This line had quotation marks missing:
header('Content-Disposition: attachment; filename=$file');
and in trying to use that line of code, the browser would prompt to save the file as $file.
The line of code should read as:
header('Content-Disposition: attachment; filename="'.basename($file).'"');
The following (tested with a binary file) with file inside the same folder as executed code.
NOTE: You could use header("Content-Type: application/text"); if it's an ASCII file.
<?php
ob_start();
$file = 'file.zip';
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream;charset=utf-8');
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));
readfile($file);
exit;
}
?>
Okay, let's add some checks and debugging.
<?php
$file = '/opt/hpws/apache/htdocs/barn/file2';
if (!file_exists($file)) {
die("The file does not exist");
}
if (!is_file($file)) {
die("Not a file"); // Worry about symlinks later
}
if (!is_readable($file)) {
die("The file is not readable");
}
die("DEBUG: Okay, will send the file -- remove this line and retry");
$name = basename($file); // Or anything else
header('Content-Type: application/octet-stream');
header("Content-Disposition: attachment; filename=\"{$name}\"");
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit();
?>
If this does not work, it should at least tell you why. Also, on the first run, the one when it will still not download the file but only tell you that it will, check that the page does not contain anything else except that one line. Otherwise, you're setting yourself up for a fall; if not this once, as soon as you have to send a file larger than your output buffers, or too many files for your system memory.
