Then you can do file_get_contents within PHP. or any file
handling
mechanism.

Hi
i am writing a web application in php
this webapp primarily focuses on file uploads and downloads

files
not
located in document root via php
Try something like that
?php
$content = file_get_contents($filename);
$etag = md5($content);
header('Last-Modified: '.gmdate('D, d M Y H:i:s',
filemtime($filename)).' GMT');
header('ETag: '.$etag);
header('Accept-Ranges: bytes');
header('Content-Length: '.strlen($content));
header('Cache-Control: '.$cache_value); // you decide
header('Content-type: '.$should_be_set);
echo $content;
exit;
?
Depending on the $filesize, you should use something else than
file_get_contents() (for example fopen/fread). file_get_contents
on
a
huge
file will exhaust your webservers RAM.
Yup, so you can map the Directory /path/to in web server config;
then
allow from only from localhost + yourdomain. This means you can
then
request it like an url and do a head request to get the etag etc
then
return a 304 not modified if you received a matching etag
Last-Modified
etc; (thus meaning you only file_get_contents when really really
needed).
I'd advise against saying you Accept-Ranges bytes if you don't
accept
byte ranges (ie you aren't going to send little bits of the file).
If you need the downloads to be secure only; then you could easily
negate php all together and simply expose the directory via a
location
so that it is web accessible and set it up to ask for auth using
htpasswd; a custom script, ldap or whatever.
And if you don't need security then why have php involved at all?
simply
symlink to the directory or expose it via http and be done with the
problem in a minute or two.
Regards!
In my opinion, serving user-content on a productive server is wicked
sick.
You don't want your visitors to upload malicous files that may
trigger
some
modules as mod_php in apache. So it makes sense to store
user-uploads
outside of a docroot and with no symlink or whatsover.
even the simplest of server configurations will ensure safety. just
use
.htaccess to SetHandler default-handler which treats everything as
static content and serves it right up.
Yes. But the average persons posting here aren't server config gods, I
believe.
Also, you can not implement permissions on these files.
The discussion was about serving files from a place outside any
docroot!
Guess there is a reason for that.
One more thing added: your RAM will be exhausted even if you open
that
600mb
file just once.
Apaches memory handling is a bit weird: if *one* apache process is
using
200mb RAM on *one* impression because your application uses that
much,
then
that process will not release the memory while it's serving another
1000
requests for `clear.gif` which is maybe 850b in size.
again everything depends on how you have your server configured; you
can
easily tell apache to kill each child after one run or a whole host
of
other configs; but ultimately if you can avoid opening up that file
in
php then do; serving statically as above is the cleanest quickest way
to
do it (other than using s3 or similar).
regards!
Sure, you could configure your apache like that. Unless you have some
traffic on your site, because the time intensive thing for apache is
to
spawn new processes. So it's just not a good idea to do that, Nor to
serve
big files via file_get_contents.
was only addressing and issue you pointed out.. anyways.. so you
propose
what exactly? don't server via apache, don't use file_get_contents
instead do..?
ps you do realise that virtually every huge file on the net is served
via a web server w/o problems yeah?
I was recommending other file methods like fopen() combinations,
fpassthru() and at best readfile(). All of them do not buffer the
whole file in memory.

http://php.net/fpassthru

Try changing above to:

I think your mail client took it out of the add_date function.

Be cautious while using this.
$mth = 1;
$pay_date = 2010-01-31;
$end_date = date('m-d-Y',strtotime($pay_date + $mth months));
echo $end_date; //03-03-2010, will take you to March

Re: [PHP] how to provide download of files mow in documentroot
Using xdebug trace, all three of them gave same number. With memory_get_peak_usage(true) file_get_contents took double the space. (file being tested was mere 4mb in size) Unable to decide what is the best way to profile such methods. Can anybody suggest? Thanks, Anshul

Also look at readfile() and fpassthru if dealing with large files.
Moreover, if you have control over the webserver then you can use PHP only
for authenticating the getFile request and offload the file delivery
operation to your webserver (Apache, NginX, lighttpd) using X-SendFile
header in the response.
