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 ?

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)

Hi Er,
1) Windows - Using apache
2) PHP 5.2.9
3) Mem Limit: 128MB
4) Size of root: 488KB
Thanks for the help.

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.
Best Regards,

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. |

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!!!! |
