How can I create a WinZip compatible AES-256 encrypted zip file from PHP on Linux?

I have to create a WinZip compatible zip file from a PHP application on a linux box, and it must use AES 256 encryption. I have found a few solutions for PHP on Windows, but they don't help me! A PHP package would be great, but if I need to, I can always have my PHP code run exec() or something to run a linux command line utility.

Any suggestions?

Winzip and PHP have nothing to do with each other first off. .zip is a file format. On Windows I have had WinZip handle .tar files which Linux creates natively. AES encryption also has nothing to do with the file format.

The question is about CREATING a zip file, not EXTRACTING one. Jason seems to be looking for a way to create a ZIP file with AES encryption, using a PHP script on a server. //EDIT: Yes, apologies for first downvoting and then commenting, should have done it in opposite order.

tar czf myCustomTar.tar *.myFiles creates a WinZip compatible archive. Therefore it should be trivial to make a system call from a php function. Granted I know nothing of PHP and my linux is limited

Pelle ten Cate is exactly right. I need to create a zip file which can be opened by WinZip.

Woot4Moo - if I can use some other tool to encrypt my files, then use tar to package them, perhaps that would work. But is this compatible with WinZip's AES encryption?

AES encryption is a type of encryption. I cannot vouche for WinZip's implementation of a well known algorithm

If a Zip application clone is not already installed on your host, just search Google for installing one of a hundred different zip applications capable of supporting both encryption and cross-platform compatibility.
Use `exec` or similar PHP function to call any available external zip application capable of zipping and applying AES-256 encryption to your target file. You'll need to know any command line switches which your zip application requires to make this happen. The target file names within your `exec` string parameter can of course be switched out using variables.
Serve your new zip file

However, should encryption not be a concern, see PHP's Zip class for making generic zip files: http://php.net/manual/en/book.zip.php
