Look at the ZipArchive class:

An example:

<?php

# array of files
$files = array(
    'feh.jpg',
    'img1.jpg'
    );

# name
$zipname = 'archive.zip';

# create the archive
$zip = new ZipArchive;
$res = $zip->open($zipname, ZipArchive::CREATE);

if($res === TRUE)
{
    foreach($files as $file)
    {
        $zip->addFile($file);
    }

    $zip->close();
}

# send to download
header('Content-type:application/zip');
header("Content-Disposition:attachment;filename='random_name.zip'");
readfile($zipname);

But if you can separate, these tasks, zip the archives in a background process and save them for a while, so that the server does not have to perform the same action multiple times.

You can create the array of files through the glob() function, a form, a database, this is up to you.

`Inline Code Example

Try This Code

<?php


    $error = "";        //error holder
    if(isset($_POST['createpdf'])){
        $post = $_POST;     
        $file_folder = "files/";    // folder to load files
        if(extension_loaded('zip')){    // Checking ZIP extension is available
            if(isset($post['files']) and count($post['files']) > 0){    // Checking files are selected
                $zip = new ZipArchive();            // Load zip library 
                $zip_name = time().".zip";          // Zip name
                if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE){       // Opening zip file to load files
                    $error .=  "* Sorry ZIP creation failed at this time<br/>";
                }
                foreach($post['files'] as $file){               
                    $zip->addFile($file_folder.$file);          // Adding files into zip
                }
                $zip->close();
                if(file_exists($zip_name)){
                    // push to download the zip
                    header('Content-type: application/zip');
                    header('Content-Disposition: attachment; filename="'.$zip_name.'"');
                    readfile($zip_name);
                    // remove zip file is exists in temp path
                    unlink($zip_name);
                }

            }else
                $error .= "* Please select file to zip <br/>";
        }else
            $error .= "* You dont have ZIP extension<br/>";

Dear cereal you have just small mistake. I have updated the code. try this code.

<?php
# array of files
$files = array(
    'profile.txt',
    'picture.jpg'
    );
# name
$zipname = 'archive.zip';
# create the archive
$zip = new ZipArchive;
$res = $zip->open($zipname, ZipArchive::CREATE);
if($res === TRUE)
{
    foreach($files as $file)
    {
        $zip->addFile($file);
    }
    $zip->close();
}
# send to download
header('Content-type:application/zip');
header("Content-Disposition:attachment;filename=$zipname");
readfile($zipname);

?>

@arslanqamar thank you for your attention! I see what you meant:

header("Content-Disposition:attachment;filename=$zipname");

And you are precisely correct. I chose to use random_name.zip instead of the $zipname value, to evidence that the name of the file can be an arbitrary value. In some cases this, together with a restricted path, can be useful to avoid direct linking to the original file.
