Create ZIP File

Hi how do i make this work please aint a clue

Hi Paul,

It pretty simple...
Step #1) Download the source code/files.
Step #2) Create a file test.php (say)
Step #3) Write this in the file:

<?php
include_once("createZip.inc.php");
$createZip = new createZip;

$createZip -> addDirectory("dir/");

$fileContents = file_get_contents("img.jpg");
$createZip -> addFile($fileContents, "dir/img.jpg");


$fileName = "archive.zip";
$fd = fopen ($fileName, "wb");
$out = fwrite ($fd, $createZip -> getZippedfile());
fclose ($fd);

$createZip -> forceDownload($fileName);
@unlink($fileName);
?>

Result: The above code will create a zip file named archive.zip which will have img.jpg it it.

Simple ?

aahh i see i have a friend who as a site and wants the downloads as zip files so need a bit of help hehe

Hi

I want to add the entire root of my website to a zip file, how do i do that?
Thanks.

Sure u can do that, just answer few of my queries first ?

1) Linux or Windows ?
2) PHP version ?
3) memory_limit ? (read from phpinfo)
4) Approx size of your root directory (in MB)

Rochak Chauhan

Hi Er,

1) Windows - Using apache
2) PHP 5.2.9
3) Mem Limit: 128MB
4) Size of root: 488KB

Thanks for the help.

Nigel

Hi,

I have updated my class. Please download and try again. I have added feature to unzip all the files and directories inside a directory.

Please note: The max size of this zip file can be less that the "memory_limit" mentioned in the php.ini.

Hi Rochak

Why is it that it outputs 4 different zip files in the working directory?
Im assuming these are temp files, can they be deleted after the zip has been created or is there a way of allowing the user to download WITHOUT saving the zip on disk?

Thanks for the help.

Simple, but if I do not want to download the file but
I just want to save it in a folder?
Thank you very much!

Hi, I have been taking a look in this class, and it is really interesting and very useful for what I want, but the problem is that I dont get what I want after several tries!!
I have a folder in my server with different kind of files in it such us .xml, .png, .jpg, etc and what I want is to get a .zip which will contain everything what is in that folder. Let's put it more clear with an example:
-Name folder: "Project"
-"Project" contains: confi.xml, picture.png, par.xml, etc...
-I want to get "Project.zip" which will have in it: confi.xml, picture.png, par.xml, etc...
Could you tell me any clue to get that with this code??? Thanks a lot in advance!!!!
