fpassthru truncating file.

Post by piersvan »

I am trying to write code to allow the download of files from a website to the user's computer. The file that downloads is truncated to 4k and is therefore not readable. What am I doing wrong? It is happening with different file types. The following is the code:

<?php
// block any attempt to the filesystem
if (isset($_GET['file']) && basename($_GET['file']) == $_GET['file']) {
$filename = $_GET['file'];
} else {
$filename = NULL;
}

$err = "<p>Sorry, the file you are requesting is unavailable.</p>";

if (!$filename) {

// if variable $filename is NULL or false display the message
echo $err;

} else {

$path = 'downloads/'.$filename;
if (file_exists($path) && is_readable($path)) {

// get the file size and send the http headers
$size = filesize($path);
header('Content-Type: image/jpeg');
header('Content-Length: '.$size);
header('Content-Disposition: attachment; filename='.$filename);
header('Content-Transfer-Encoding: binary');

// open the file in binary read-only mode
// display the error messages if the file can´t be opened
$file = fopen($path, ‘rb’);

if ($file) {

// stream the file and exit the script when complete
fpassthru($file);
exit;

} else {

echo $err;

}

} else {

echo $err;

}

}

?>
