Understanding the Basics of Zip File Creation

Crafting a Simple PHP Function: createZip()

To initiate the zip file creation process, we introduce a straightforward PHP function named createZip(). This function proves to be a versatile tool, allowing you to effortlessly compress and bundle various files, be it images, documents, or any other essentials.


/* create a compressed zip file */

function createZip($files = array(), $destination = '', $overwrite = false) {

    if(file_exists($destination) && !$overwrite) { return false; }

    $validFiles = [];

    if(is_array($files)) {
        foreach($files as $file) {
            if(file_exists($file)) {
                $validFiles[] = $file;

    if(count($validFiles)) {
        $zip = new ZipArchive();
        if($zip->open($destination, $overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true) {
            return false;

        foreach($validFiles as $file) {
            $zip->addFile($file, $file);

        return file_exists($destination);
    } else {
        return false;

$fileName = '';
$files_to_zip = ['demo1.jpg', 'demo2.jpg'];
$result = createZip($files_to_zip, $fileName);

header("Content-Disposition: attachment; filename=\"".$fileName."\"");
header("Content-Length: ".filesize($fileName));


Step-by-Step Guide to Executing the Code


Ensure that you have two image files, namely:

  1. demo1.jpg
  2. demo2.jpg

Executing the Code:

  1. Copy the provided index.php file.
  2. Place the two image files (demo1.jpg and demo2.jpg) in proximity to the index.php file.
  3. Run the entire code snippet.


By following this comprehensive guide, you've successfully acquired the skills to create a zip file using PHP's ZipArchive. This efficient process allows you to package and distribute files seamlessly, enhancing user experience and file management.
