download more than one file at a time or Dynamically create the zip file and download it

To download more than one file at a time to create all the file as a zip file and download it.

To create the file dynamically you must enable the extension=php_zip.dll in your php.ini and restart your wamp.

Here is the example


/* creates a compressed zip file */
function create_zip($files = array(),$destination = ”,$overwrite = false) {
//if the zip file already exists and overwrite is false, return false
if(file_exists($destination) && !$overwrite) { return false; }
$valid_files = array();
//if files were passed in…
if(is_array($files)) {
//cycle through each file
foreach($files as $file) {
//make sure the file exists
if(file_exists($file)) {
$valid_files[] = $file;
//if we have good files…
if(count($valid_files)) {
//create the archive
$zip = new ZipArchive();
if($zip->open($destination,$overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true) {
return false;
//add the files
foreach($valid_files as $file) {
//echo ‘The zip archive contains ‘,$zip->numFiles,’ files with a status of ‘,$zip->status;

//close the zip — done!

//check to make sure the file exists
return file_exists($destination);
return false;

// File name to zip

$files_to_zip = array(
//if true, good; if false, zip creation failed
$result = create_zip($files_to_zip,’’);
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(‘’).”;” );
header(“Content-Transfer-Encoding: binary”);
header(“Content-Length: “.filesize(‘’));
