Are there any best practices for efficiently loading and displaying multiple images in PHP?

When loading and displaying multiple images in PHP, it is important to optimize the process for efficiency. One way to achieve this is by using lazy loading techniques, where images are loaded only when they are in the viewport of the user. Additionally, caching images can help reduce load times by storing them locally after they have been loaded once.

<?php

// Array of image URLs
$images = array(
    'image1.jpg',
    'image2.jpg',
    'image3.jpg'
);

// Loop through the array and display images
foreach ($images as $image) {
    echo '<img src="' . $image . '" alt="Image">';
}

?>
