How to zip a folder and download it using php?

Question

I have folder named \"data\". This \"data\" folder contains a file \"filecontent.txt\" and another folder named \"Files\". The \"Files\" folder contains a \"info.txt\" file.

You need to recursively add files in the directory. Something like this (untested):

function createZipFromDir($dir, $zip_file) {
    $zip = new ZipArchive;
    if (true !== $zip->open($zip_file, ZIPARCHIVE::CREATE | ZIPARCHIVE::OVERWRITE)) {
        return false;
    }
    zipDir($dir, $zip);
    return $zip;
}

function zipDir($dir, $zip, $relative_path = DIRECTORY_SEPARATOR) {
    $dir = rtrim($dir, DIRECTORY_SEPARATOR) . DIRECTORY_SEPARATOR;
    if ($handle = opendir($dir)) {
        while (false !== ($file = readdir($handle))) {
            if (file === '.' || $file === '..') {
                continue;
            }
            if (is_file($dir . $file)) {
                $zip->addFile($dir . $file, $file);
            } elseif (is_dir($dir . $file)) {
                zipDir($dir . $file, $zip, $relative_path . $file);
            }
        }
    }
    closedir($handle);
}

Then call $zip = createZipFromDir('/tmp/dir', 'files.zip');
