PHP How to create a ZIP Archive
How to create a ZIP Archive:

Here you are shown how to create a ZIP archive. This can be useful if let's say that you want your user to download some files, and they are some that she picks from a list (so its a dynamic collection of different files, and therefor maybe not a good idea, to be a pre-made Zip package). Then you can pack the files on the fly and let your user download that ZIP package. Maybe remember to delete that ZIP file again, after use. :-)

 Create a Zip archive

How do you create a compressed archive using PHP?

This example will show you how you create a ZIP file with the file syou want to have for your users to download.
You can f.ex use this, if your users are to download a huge bunch of files, lik images. Then you can zip them on the fly, and let your user download a single Zip file instead of havign to download them all, one by one.
