What are best practices for structuring PHP scripts for galleries to prevent duplicate data and optimize loading times?

To prevent duplicate data and optimize loading times in PHP scripts for galleries, it is best to utilize caching techniques to store and retrieve data efficiently. One approach is to implement a caching mechanism that stores the gallery data in a file or database to avoid redundant database queries and speed up loading times. 

// Example of caching gallery data to prevent duplicate data and optimize loading times

// Check if cached data exists
if(file_exists('cached_gallery_data.json')) {
    // Retrieve data from cache
    $gallery_data = json_decode(file_get_contents('cached_gallery_data.json'), true);
} else {
    // Fetch data from database
    $gallery_data = fetch_gallery_data_from_database();

    // Cache the data
    file_put_contents('cached_gallery_data.json', json_encode($gallery_data));
}

// Display gallery using the cached data
foreach($gallery_data as $image) {
    echo '<img src="' . $image['url'] . '" alt="' . $image['alt'] . '">';
}
