Zip archive and Windows

Hi Guys

 

This is a bit of a weird one and I wondered if perhaps someone here had experienced this and found a work around.

 

I'm using zip archive on a project at the moment. Basic version of the code is below.

 

When I zip a file and output it to the browser using headers it works fine in the example below. BUT if I try to add a file from another directory, as in the commented out line below, the resulting zipped folder can't be unzipped in windows. When I try I get a "The folder XXXX is invalid" message.

 

I sent the same zipped folder to my htc phone and it opened the zipped folder no problem.

 

The puzzling thing about windows is that it works fine if the image originates in the same directory as the executing script and can be opened no problem.

 

So is this something anyone else has encountered? And how can you get around it?

$zip = new ZipArchive();
                if ($zip->open('./test2.zip',ZipArchive::CREATE) === TRUE) {
                               
                              //$zip->addFile('../fileUploadLocation/somefolder/image1.jpeg');
                                $zip->addFile('image3.jpeg');
                                $zip->close();
                                echo 'ok';
                } else {
                                echo 'failed';
}

You need to use the second parameter to give the file an alternate name or else the file will be added with the full linux path and won't unzip on windoze:

$zip->addFile('../fileUploadLocation/somefolder/image1.jpeg', 'image1.jpeg');
//or maybe this for a subdir
$zip->addFile('../fileUploadLocation/somefolder/image1.jpeg', 'somefolder/image1.jpeg');
