How can PHP scripts be optimized to handle resource-intensive tasks like reading images from directories and inserting them into a database without affecting user experience?

To optimize PHP scripts for resource-intensive tasks like reading images from directories and inserting them into a database without affecting user experience, you can use techniques such as lazy loading, pagination, and asynchronous processing. This involves breaking down the tasks into smaller chunks, loading only what is needed at a given time, and executing tasks in the background to prevent blocking the user interface. 

// Lazy loading images from directory and inserting into database
$directory = 'images/';
$files = scandir($directory);

foreach ($files as $file) {
    if (in_array(pathinfo($file, PATHINFO_EXTENSION), ['jpg', 'jpeg', 'png', 'gif'])) {
        // Insert image into database asynchronously using AJAX or background processing
        // Example: exec("php insert_image.php $file > /dev/null &");
    }
}
