How can PHP scripts be optimized to preload data and improve page loading times for administrators?

To optimize PHP scripts to preload data and improve page loading times for administrators, you can use caching techniques such as storing data in memory or using a persistent data store like Redis. By preloading data that is frequently accessed by administrators, you can reduce the number of database queries and improve overall performance.

// Example code snippet using Redis to preload data
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);

$data = $redis->get('admin_data');

if (!$data) {
    // If data is not in cache, fetch it from the database
    $data = fetchDataFromDatabase();

    // Store data in cache for future use
    $redis->set('admin_data', $data);
}

// Use the preloaded data for page rendering
echo $data;
