Zip

[mfazi]

hello,
Can a made zip file using PHP. If yes then help me how i can made it

[hand]

creating ZIPs with PHP direct´ly is not suppoerted.

But if safe_mode is set to off, then it is possible to execute external programs

`tar cvfz ......`;

Well.... the question was to create a compressed file with php/unix/linux en the extract it on a windows machine.

<? exec (tar -zcvf file.tar.gz file1.txt file2.jpg); ?>

Now I want to turn it the other way around.
Because I'm visiting a lot of Honda car events, and I'm making photo's during thes events, it often happends that I want to publish 100 to 150 photos.

I made a photo gallery with a special upload form takes the original photo, makes a thumbnail and puts it together in a nice photobook.
Because of the large amounts of photo's (100 to 150) it takes a lot of time to fill out the upload form.
Now I had a new idea. Let's put all 100 to 150 photos in one zip file. Upload it to the photo gallary, let the gallary take out the photo's from the zip file and do what it already did... make thumbnails and the gallary.
I already have a little piece of code, but that only seems to work with GZipped files en not with files created by winzip.

<?
$file = "./testphoto.jpg" ;
$fp = fopen("$file", "w") ;

$filename = "test.zip" ;
$zp = gzopen($filename, "r");

if ($zp) {
   while (!gzeof($zp)) {
      $buff1 = gzgets ($zp, 4096) ;
      fputs($fp, $buff1) ;
   } 
} 
gzclose($zp) ;
fclose($fp) ;
?>

Can someone tell me how I can extract files stored in a archive created with WINZIP?

Greatzzz..

As the other post said, you will have to use a shell command to execute an external zip decompression program. just the same as creating a zip.

I already tried to

exec ('tar -zxvf test.zip');
exec ('tar -Zxvf test.zip');
exec ('tar -Ixvf test.zip');

But non off these dit work out in any way.
All I got were error messages becaus tar could not uncompress the files. To tar it doesn't seem to be a compressed archive.

Will you not need to excecute a windows application if you are extracting on a windows machine ? for example try using pkunzip or a similar program.

[Orthello]

The server running the scripts is a Linux machine.
The clients, the ones visiting and updating the gallery are 99% of the time windows machines with WINZIP on it.
So that's why 2 different os's are involved.

I'm 'playing' with gunzip on the linux box at this moment and that's is more like it. I can extract one file from an archive with.. one file. Decompressing is going creat but now the problem.. handeling MORE than one file 😃

I'll keep in touch!!

Would you like to have gZip ( .gz ). It requires Zlib which is generally there 🙂

ok... I downloaded Unzip for Linux.
This is a precompiled binary of the Unzip programme.
I putted it in the binary directory of linux en changed the script...

<?
..
.. // som other code
..
exec('unzip testen.zip');
..
.. // som other code
..

And it worked!!!!
