[PHP] Autorename extracted files from zip-archive
Hello,
I am using shell_exec to uncompress zip files which works fine, but has
one big problem. Whenever the zip-archive containes an already existing
file name, it will overwrite the current one. I need the file to be
extracted and autorenamed.
This is the code line:
$output = shell_exec('unzip -jo '.$filename.' -d '.$path);
Does anybody know a way on how to autorename existing files?
I thought about a workaround on extracting to a tmp folder and then
moving to the proper directory while renaming the files if they already
exists. Unfortunatelly I could not find a way to do this.
Thank you for any help on this.

Just because you're using PHP as a frontend doesn't mean this is a
PHP question. This is a Linux administration question, and one that
Google can handle.

Probably because you haven't written it yet. When you think about
how to achieve this, it's really simple:
1.) Create a temporary directory (e.g. -
mkdir(dirname(__FILE__).'/tmp'.time()) for a unique name).
2.) Extract the files to that directory.
3.) Check the target directory for existing files.
4.) Handle things as appropriate.
There are even simpler ways, again available by searching Google,
you may just need to adjust your search terms and try again.

Merlin,
It's a shame that unzip doesn't have that feature like unrar. However, I
suggest you extract the contents of the zip files into a temp working
directory. Scan the files within that directory for any compressed archives
and extract each into their own subdirectory matching the filename. And
just recurse until no more compressed archives. Then process whatever files
you need. When done, just rm -fd tmpworkdir (my unix/linux is limited.
Don't recall the parameters). That way, clean up is a synch and you still
have the original file when there's something wrong during processing stages
like mismatch columns, duplicate entries, etc.
Regards,
Tommy

As you are using an external app (unzip), does it support any sort of
renaming? PHP isn't actually involved in the extraction process in
this instance.
You may be better off using the ZIP extension in PHP to extract the
data and write it to your own files.
