Re: [PHP] Using named Pipes between PHP and ZIP
Unfortunately it makes no difference if i use zip with 2 - or if I leave them ommited. The longer I guess about it, the more I think it might be a ZIP topic, namely how the stream to stdin needs to be like so zip will know the name of the file from it.

Regards, Dennis This is a known problem with zip, it's just not possible. Either you select files, or you pass something on stdin (which will have no filename). You will have to do the same trick with mkfifo, but you can use the php function posix_mkfifo[1] for that. - Matijn [1] php.net/posix_mkfifo -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Using named Pipes between PHP and ZIP
Hello everyone,
I'm looking for a solution for the following:
1) collecting data from a simple html form and send them to a php script
2) take the data and place them in a php-generated excel sheet
3) zip the excel sheet and password protect the zip file (standard
encription will be sufficent, no AES needed)
4) send the zip file as an email attachment
This kind of output is fixed, changing the output is not an option.
I'm ok with building the excel sheet and sending the mail, but I'm still
trying and error with the zip. Since I need password protection in the zip,
I cannot use the php build in zip extension. I guess I will need to call ZIP
on the shell. I'm aware I could first save the generated excel sheet to the
filesystem and afterwards call the zip process on the file, putting the zip
file also to the file system. But I wonder if there's an option to stream
the data till they finally can be put to the multipart mail - without saving
anything to the filesystem.
Here is my first try, just a little modification of the example on proc_open
in the php docu. To keep the test simple, I load a sample xls from the
filesystem instead of generating from the php class and output it directly
to the browser. The script works well except one point: the file contained
in the zip will have no name an no file extension.
?php
header ('Content-type: application/zip');
header ('Content-Disposition: attachment; filename=download.zip');
$descriptorspec = array(
0 = array(pipe, r),
1 = array(pipe, w),
2 = array(file, error-output.txt, a)
);
$dateiname = 'xyz.xls';
$file = fread(fopen($dateiname, r), filesize($dateiname));
$process = proc_open('zip -P 1234', $descriptorspec, $pipes);
if (is_resource($process)) {
fwrite($pipes[0], $file);
fclose($pipes[0]);
$zip = stream_get_contents($pipes[1]);
fclose($pipes[1]);
$return_value = proc_close($process);
}
echo $zip;
?
So I look for an option to get the name and extension in the zipfile. Here I
found named pipes as an option. Calling via shell, tested with a textfile in
order to use less
mkfifo xyz.txt
less readme.txt xyz.txt zip output.zip -FI xyz.txt -P 1234
rm xyz.txt
Now I get a pw protected zip file containing xyz.txt. Now how can I combine
both? How can I tell php to use the named pipe instead of stdin in
proc_open? Or any other idea to get the file in the zip the correct name and
extension.
Thanks in advance,
Regards,
Dennis

I *think* all you need in the first paramter to proc_open is :
zip -P password - -
The first - is the zip file -- which will be send to stdout.
The second - is the input -- which you should pipe your spreadsheet into.
Good luck!

[PHP] Using Named Pipes
I'm trying to use a named pipe in PHP, but I have a feeling I'm misunderstanding something. I'm hoping someone might have some insight. Here's the basic outline of what I'm doing posix_mkfifo($argfile, 0600) $argp = fopen($argfile, w+); $command = program $argfile; $fp = popen($command, r); fputs($argp, 'data = ' . $post); $response = fgetcsv($fp, 1000); The named pipe is being created ok. But my page hangs while trying to read the response in the last line. Everything works fine if I replace the named pipe with a standard file. So it really seems that it is the use of the named pipe that is wedging me. Any thoughts? -- JR -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
