How can PHP be optimized for processing and analyzing a large number of images in a series efficiently?

To optimize PHP for processing and analyzing a large number of images efficiently, consider using libraries like GD or Imagick for image manipulation tasks. Additionally, implement techniques such as caching processed images to reduce the load on the server and improve performance. Parallel processing can also be utilized to handle multiple images simultaneously, further speeding up the process. 

// Example code snippet using Imagick library for processing images in parallel

$images = ['image1.jpg', 'image2.jpg', 'image3.jpg'];

$workers = 4; // Number of parallel processes

$workersPool = [];

foreach ($images as $image) {
    $pid = pcntl_fork();
    
    if ($pid == -1) {
        die('Could not fork');
    } elseif ($pid) {
        $workersPool[] = $pid;
    } else {
        // Process image using Imagick
        $imagick = new Imagick($image);
        $imagick->resizeImage(200, 200, Imagick::FILTER_LANCZOS, 1);
        $imagick->writeImage('processed_' . $image);
        $imagick->clear();
        $imagick->destroy();
        
        exit();
    }
}

foreach ($workersPool as $worker) {
    pcntl_waitpid($worker, $status);
}
