// here choose folder used.             $dirname = public_path() . '/uploads/packs/'.$pack_id;              // choose name archive.             $zipfilename = 'myzip.zip';              // create "mycoolname.zip" file in public directory of project.             $zip = new ziparchive;              if ( $zip->open( public_path() . '/' . $zipfilename, ziparchive::create ) === true )             {                 // copy files folder , place them in archive.                 foreach ( glob( $dirname . '/*' ) $filename )                 {                     $file = basename( $filename );                     $zip->addfile( $filename, $file );                 }                  $zip->close();                  $headers = array(                     'content-type' => 'application/octet-stream',                 );                  // download .zip file.                 return response::download( public_path() . '/' . $zipfilename, $zipfilename, $headers ); 

can me, why getting not exist error?

thank you!

from laravel documentation: http://laravel.com/docs/4.2/responses#special-responses

creating file download response

 return response::download($pathtofile);  return response::download($pathtofile, $name, $headers); 

maybe should avoid repeat second

$zipfilename

in last line of code.
