Adakalanya kita membutuhkan script untuk mendowload beberapa file menjadi satu file zip untuk mempermudah dalam melakukan download pada halaman website.

Berikut cara membuat script untuk proses pengabungan file menjadi satu file zip :

<?php
$directory = "Directory_Name";
$zip_file_name = "Nama_File.zip";
$download_file = true;

class FlxZipArchive extends ZipArchive {
    /** Add a Dir with Files and Subdirs to the archive;;;;; @param string $location Real Location;;;;  @param string $name Name in Archive;;; @author Nicolas Heimann;;;; @access private  **/

    public function addDir($location, $name) {
        $this->addEmptyDir($name);
        $this->addDirDo($location, $name);
     } // EO addDir;


    /**  Add Files & Dirs to archive;;;; @param string $location Real Location;  @param string $name Name in Archive;;;;;; @author Nicolas Heimann
     * @access private   **/
    private function addDirDo($location, $name) {
        $name .= '/';
        $location .= '/';

        // Read all Files in Dir
        $dir = opendir ($location);
        while ($file = readdir($dir))
        {
            if ($file == '.' || $file == '..') continue;
            // Rekursiv, If dir: FlxZipArchive::addDir(), else ::File();
            $do = (filetype( $location . $file) == 'dir') ? 'addDir' : 'addFile';
            $this->$do($location . $file, $name . $file);
        }
    } // EO addDirDo();
}

$zip_achive = new FlxZipArchive;
$$zip_achive_open = $zip_achive->open($zip_file_name, ZipArchive::CREATE);
if($$zip_achive_open === TRUE)
{
    $zip_achive->addDir($directory, basename($directory));
    $zip_achive->close();
} else  { 
    $download_file = false;
    echo 'Could not create a zip archive';
}

if ($download_file)
{
    ob_get_clean();
    header("Pragma: public");
    header("Expires: 0");
    header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
    header("Cache-Control: private", false);
    header("Content-Type: application/zip");
    header("Content-Disposition: attachment; filename=" . basename($zip_file_name) . ";" );
    header("Content-Transfer-Encoding: binary");
    header("Content-Length: " . filesize($zip_file_name));
    readfile($zip_file_name);
    unlink($zip_file_name);
}

?>

Selamat mencoba, terima kasih
