How can ZIP archives be utilized to efficiently store and retrieve images in PHP?

To efficiently store and retrieve images in PHP, ZIP archives can be utilized to compress and bundle multiple image files into a single file. This can help reduce storage space and streamline the process of transferring or downloading images. By using PHP's ZipArchive class, you can easily create, extract, and manipulate ZIP archives containing image files. 

// Create a ZIP archive and add image files
$zip = new ZipArchive();
$zipFileName = 'images.zip';
if ($zip->open($zipFileName, ZipArchive::CREATE) === TRUE) {
    $images = ['image1.jpg', 'image2.png', 'image3.gif'];
    foreach ($images as $image) {
        $zip->addFile($image);
    }
    $zip->close();
}

// Extract image files from the ZIP archive
$zip = new ZipArchive();
if ($zip->open($zipFileName) === TRUE) {
    $zip->extractTo('extracted_images/');
    $zip->close();
}
