How can PHP be optimized to handle a large number of images in a gallery efficiently?

To optimize PHP for handling a large number of images in a gallery efficiently, you can implement lazy loading techniques to only load images as they are needed, use caching mechanisms to reduce server load, and resize images to appropriate dimensions to reduce file size and loading time. 

// Example code for lazy loading images in a gallery
echo '<div class="gallery">';
foreach ($images as $image) {
    echo '<img data-src="' . $image['url'] . '" class="lazy-load">';
}
echo '</div>';

// Example code for resizing images
function resize_image($image_path, $width, $height) {
    list($orig_width, $orig_height) = getimagesize($image_path);
    $image = imagecreatetruecolor($width, $height);
    $source = imagecreatefromjpeg($image_path);
    imagecopyresampled($image, $source, 0, 0, 0, 0, $width, $height, $orig_width, $orig_height);
    imagejpeg($image, $image_path);
}
