Hello fellow stakoverflowers,
I'm having a problem with PHP/Apache. I have an application that allows the admin to upload 100Mb files. The uploading works well but I'm having problems with the downloading.
It works perfectly with smaller files (tested with a 50Mb file) but for some reason I can't get the 100 Mb files.
Here's my php code
$extension = 'zip'; //for testing
switch ($extension) {
case "dwg": $contentType="image/vnd.dwg"; break;
case "dxf": $contentType="image/vnd.dxf"; break;
case "pdf": $contentType="application/pdf"; break;
case "zip": $contentType="application/zip"; break;
case "png": $contentType="image/png"; break;
case "jpeg": $contentType="image/jpeg"; break;
case "jpg": $contentType="image/jpg"; break;
case "gif": $contentType="image/gif"; break;
default:
$contentType = '';
}
@header("Content-type: " . $contentType);
@header("Content-Disposition: attachment; filename=$filename");
@header("Cache-Control: no-cache, must-revalidate");
@header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // passed date
echo file_get_contents($url);
I've also tried other solutions I found on SO.
header('Content-Description: File Transfer');
header('Content-Transfer-Encoding: binary');
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-type: " . $contentType);
header("Content-Disposition: attachment; filename=\"".$filename."\"");
header("Content-Length: ".filesize($url));
echo self::url_get_contents(URL_PUBLIC . $url);
...
private function url_get_contents ($url) {
if (!function_exists('curl_init')){
die('CURL is not installed!');
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);
echo $output;
return $output;
}
Or
$file_contents = fopen($url, "r");
echo $file_contents;
fclose($file_contents);
All solutions return the same thing. A file size of 0 Kb. Like I said, smaller sized files works.
Also, when I test locally, the 100 Mb size files download correctly so my guess is that the problem comes from the server. I've changed the php.ini as follows
register_globals = Off
magic_quotes_gpc = Off
post_max_size = 128M
memory_limit = 256M
upload_max_filesize = 128M
max_execution_time = 120
expose_php = off
session.save_path = /tmp
mysqli.default_socket = /tmp/mysql5.sock
mysql.default_socket = /tmp/mysql5.sock
It's probably a memory limit problem but not sure.
