class zipfile - Create a zip archive file

This script is useful to package several files on the fly into a single downloaded archive.

Example:

// build a zip archive
    include_once 'zipfile.php';
    $zipfile = new zipfile();

    // place all files into a single directory
    $zipfile->store('files/', time());

    // archive each file
    foreach($items as $id => $name) {

        // read file content
        if($content = Safe::file_get_contents($file_path.$name)) {

            // add the binary data stored in the string 'filedata'
            $zipfile->store('files/'.$name, Safe::filemtime($file_path.$name), $content);
        }
    }

    // suggest a download
    Safe::header('Content-Type: application/zip');
    Safe::header('Content-Disposition: attachment; filename="download.zip"');

    // send the archive content
    echo $zipfile->get();
    return;
