Zip FPDFs files? - php

Question

I have a php script where I can easily download a pdf file using fpdf library. The script takes in ID of multiples rows from DB and downloads PDFs for each ID. How do I download multiple pdfs as once with zip? That is I send ID value to another script and that script then collects all IDs and downloads it in zip file?
<?php
//include connection file
ob_start();
include_once('fpdf/fpdf.php');
$db = new PDO("mysql:host=localhost; dbname=db;charset=utf8",'root','');
class PDF extends FPDF
{
// Page header
function Header()
{
$this->SetFont('Arial','B',14);
$this->Cell(276, 5, 'Details', 0, 0, 'C');
$this->Ln();
$this->SetFont('Times', '', 12);
//$this->Cell(276, 10, 'Details of students', 0, 0, 'C');
$this->Ln(5);
}
function viewTable($db)
{
$id=$_GET['id'];
$sql = "SELECT * FROM Datas WHERE ID = '$id'";
$stmt = $db->query($sql);
}
}
$id=$_GET['id'];
$pdf = new PDF('P','mm','A4');
$pdf->AliasNbPages();
$pdf->AddPage('L','A4',0);
$pdf->viewTable($db);
$pdf->Output("D", "$id.pdf");
ob_end_flush();
?>

Got it! I created ZipArchive and sent file path to zip file.
$pdf->Output("F", "$id.pdf");
$zip = new ZipArchive;
$tmp_file = 'Documents.zip';
//if ($zip->open($tmp_file, ZipArchive::CREATE))
if($zip->open($tmp_file, ZipArchive::OVERWRITE|ZipArchive::CREATE)) {
$zip->addFile("$id.pdf", "$id.pdf");
$zip->close();
echo 'Archive created!';
header('Content-disposition: attachment; filename=Documents.zip');
header('Content-type: application/zip');
} else {
echo 'Failed!';
}
ob_end_clean();
readfile($tmp_file);
