<?php// Get real path for our folder
include_once 'includes/db_connect.php';
if (isset($_POST['zip'])){
$sql = "SELECT folder FROM `pancard`";
$result = mysqli_query ($dbcon, $sql);
while ($row = mysqli_fetch_array ($result)){
$rootPath = realpath('../pancard/'.$row['folder'].'/');
$file = 'file.zip';
$zip = new ZipArchive();
$zip->open('$file', ZipArchive::CREATE | ZipArchive::OVERWRITE);
$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($rootPath),

foreach ($files as $name => $file)
{
if (!$file->isDir())
{
$filePath = $file->getRealPath();
$relativePath = substr($filePath, strlen($rootPath) + 1);
$zip->addFile($filePath, $relativePath);
