Hi
I am having trouble with a file transfer script, as you can see, I am
trying trying to keep the code as simple as possible.
But everytime I download a file with it, it is corrupt. For example,
when
I download a small .rar file, just to test, it is always corrupt
('Unexpected end of archive'). I also cleared my browser cache just to
be
sure, but same problem.
I just can't get my head around why it wouldn't be working as it is...
A couple of questions:
Have I got too many header requests?
Do I need to worry about output buffering, which is possibly corrupting
the file output (if so, please tell me what to do!)?
Is there an easier way to get returned response header and get a
redirected link, instead of finding and cutting strings?
Is there maybe something wrong with the structure or order of the header
requests, and/or returned headers etc?
Here is what I have so far:

$leftLen = strlen(stristr($str, $right));
$leftLen = $leftLen ? -($leftLen) : strlen($str);
$str = substr($str, 0, $leftLen);
return $str;
}

Thanks to anyone who has already helped, I hope some genius can spot an
obvious error, because this is just beyond me!
:)
I'd be correct in assuming that you have opened up the download in a
text browser to see what you've actually recieved yes?
first thing to check... your doing a fsockopen, and posting a raw http
request, meaning your getting a raw http response back, which you're
echoing straight out, so you should expect to have full http headers and
quite possibly http chunked content, rather than a nice file..
use file_get_contents with a stream_context holding all your http
request headers instead, as an easy way around it.
or check out the http class, or use zends http class, or create a quick
chunk decoder - whichever you do, first step is to actually check the
raw content and verify it's not just a raw http response :)
Nathan
Thanks for the reply, Nathan
I actually have since found more about this 'erroneous' output; the script
is outputting response headers as part of the file I download!, and also
seems to chop a bit off the end of the file (checking with a text file, of
course!)
So I will try to do what you suggest - thanks for the help. If anyone has
any suggestions on a chunk decoder, or maybe a quick example of
file_get_contents() with a stream context, feel free... :)

I thought competitions usually give some more or less "abstract" tasks,

So not worth the time and effort. Any person capable of doing the code
conversion (to AT LEAST C, Python, and Perl nonetheless) is smart enough
to know the potential payoff is worse than flipping burger and
McGeneric's.
Cheers,
Rob.

Hi,
i would like to have a flash menu in my PHP website.
this is no problem.
My problem is how to exchange data between PHP andFlash (in both direction).
i found a lot of posts on this theme, but nothing with really works under
ActionScript 3 and PHP.
does anyone already solved such topic ?
thx.
I researched this some time ago...
You can pass parameters to flash movie in ONE of the parameters it
accepts (don't remember which one, but you can find out). This means,
you can't pass each parameter separately, but you have to pack them,
somehow (not sure what separators are allowed) and then unpack them
inside the movie.
As to passing parameters from the flash movie to the php - basically if
people can click inside the movie, you can perhaps send GET or POST
requests back to the server, which your php can interpret.

Thanks
I have already another post dealing with this issue. (check newsgroup for
Server to client file transfer always corrupt).
I had figured out the problem that was corrupting the file, it is the
response headers that are being added to the file when it is downloaded,
and i don't know how to trim them. I am using a different trim method i
'borrowed' from another script (where it seems to work perfectly!), and I
just can't understand why it won't work for me, unless as u say, there are
other errors being output, but I have looked at the text file and I don't
see anything other than the headers there. When I use the trim script to
remove them, it also seems to remove part of the start and end of the text
file.
I think the most annoying aspect of whole thing is why it is so difficult
to find a solution to this problem, i'm sure other people must have come
across this problem?
thanks again :)

You can use filesize() to get the file size...
http://php.net/filesize
If that's not going to work because you are stripping out part of the
file, or something, Use fgets to get the header info, and then use
fseek to reset the file pointer to the beginning:
http://php.net/fseek
<?php fseek($file, 0);?>
You can then read as much or as little as you like with fread.
As far as the corrupt files go, compare what you got with the download
and the original in a text editor or a hex editor to see what
happened.
You might have some PHP warnings or notices at the front of the file,
or at the end, messing the file contents up.

Hello Richard
Well, thank you for pointing that out to me! I was actually trying to
read
it into RAM, but that was a silly mistake.
But now I have the problem that, even though you are correct, the
problem
seems to still remain, in the sense that I actually *need* to read the
start of the file just to get the header info (so i can retrieve the
Content-Length, and the filename).
Since I tried your method above, I thought I had got the script to
finally
work - which it seemed to - but every file I download with it is
corrupt.
I tried downloading a WinRAR file, and I get 'unexpected end of
archive'.
:( I know for a fact that the archive itself is NOT corrupt, because I
tried it with various different files and all of them ended up
corrupt!
I found some info on the net about fread() and fgets(), and it seems
that
fgets() only reads one line of data up to 1024 bytes, or in my case,
64
bytes. This is what I want to happen, because I need the 'reading' to
abort/break when I have read the required info from the header...I
wish
(and hope!) there was an easier way to get this info other than
searching
for it. :|
Now I am truly vexed because the files are all corrupt when
downloaded,
because I can't see anything wrong with the code. I have added a few
comments, so you can see what I think is the problematic area.
By the way, many thanks for your enthusiastic help so far! - I hope
you
don't take this email to mean I will be mailing you frequently,
believe me
I know you must be busy, and I only mailed you as a last resort!
Thanks again!

unset($_SESSION);
or
$_SESSION = array();
This reset all of the session variables. To reset only one, try this:
<?php
unset($_SESSION['key']);
?>

Resetting all session variables or one of those session vars ?
If you need to reset all then use *session_destroy() *function.
Hope it helps..

Hi
there are 2 functions
session_unset('Key');
session_destroy();
please find them in the manual. i think they are the 2 used for setting and
usetting the session.

You could set up Gmail's filters.

Yes you can.
Just mirror the additional domains and in your PHP app check the
$_SERVER["HTTP_HOST"] variable.
Hope this helps !

it came through :-)
More concrete example? What would you like to see?
the column spec. what kind of geomtery column is it? and
are you using it as a primary key? or some else ... if so what kind
of stuff are you storing in there? also in what way are you
using it that gives you such a speed boost with queries?
I read the mysql docs, I understand the principles but I'm having
a hard time figuring out how to apply in practice in terms of
making use of the performance gains you mentione ... specifically
in a web environment where heavy queries are often along the lines
of paginated data combined with user defined filters (e.g. a product
list sorted by price, etc and filter on type/category/keyword/etc)
sorry if I'm sounding like a idiot :-)
I suspect that some of my mail is getting dropped :(

I for one would really like to see a concrete example of this kind of

On one of my local postGIS tables:
CREATE INDEX k1

USING gist
(the_geom);
A gist index is a GEOS based spatial index. You will need GEOS to create
one.
When loading spatial data, your geometry column looks like so:
01050000000100000001020000000C00000011ECE564CF7561404A8999CCDABC4140E5C0981ACE75614012901CD641BD4140603C8386BE756140E525611B40BD41405BF216D3BD756140151DC9E53FBD414054DC1A4DBD756140760B997A3FBD414012219BD1BC756140D20823E33EBD41407AB2884EBC7561400F2110243EBD41404571B4D0BB756140CC0C6A213DBD4140F707192ABB7561405DF2A1803CBD4140F0F11CA4BA756140C3D1B7413CBD4140E89CB2ADB97561406F046D233CBD414017D4B7CCA97561406D47AD7F39BD4140
Which is WKB (Well Known Binary) data or WKT (Well Known Text) data. The
gist index simply indexes this as opposed to the regular gid (which you
still use btree indexes on anyways)
