In what ways can PHP developers optimize code for better performance and readability when working with image galleries?

When working with image galleries, PHP developers can optimize code for better performance and readability by implementing lazy loading techniques to only load images when they are needed. This can help reduce the initial loading time of the gallery and improve overall user experience. Additionally, developers can use caching mechanisms to store processed images and avoid repeatedly generating them, further enhancing performance. 

// Lazy loading images in gallery
echo '<div class="image-gallery">';
foreach ($images as $image) {
    echo '<img data-src="' . $image['url'] . '" alt="' . $image['alt'] . '">';
}
echo '</div>';

// Caching processed images
$cacheKey = 'processed_images_' . md5(serialize($images));
$processedImages = apc_fetch($cacheKey);

if (!$processedImages) {
    $processedImages = [];
    foreach ($images as $image) {
        $processedImage = processImage($image['url']);
        $processedImages[] = $processedImage;
    }
    apc_store($cacheKey, $processedImages);
}

function processImage($imageUrl) {
    // Code to process image
    return $processedImage;
}
