In Laravel, you can use cache to store query results by utilizing the caching mechanism provided by the framework. Here's a step-by-step guide on how to do it:

  1. Make sure you have a caching driver configured in your config/cache.php file. You can use various caching drivers such as Memcached, Redis, or database. For simplicity, we will use the default file driver in this example.
  2. In your controller or wherever you want to store the query results, you can use the cache() function to store and retrieve data from the cache. Here's an example:

use IlluminateSupportFacadesCache;

public function getData()
{
    $key = 'cached_query_results';
    
    // Check if the data is already cached
    if (Cache::has($key)) {
        $data = Cache::get($key);
        return $data;
    }

    // If the data is not cached, fetch it from the database
    $data = YourModel::where('column', 'value')->get();

    // Store the query results in the cache for a specific time (e.g., 1 hour)
    Cache::put($key, $data, now()->addHour());

    return $data;
}


  1. When you call the getData() method, it will first check if the data is already cached. If it is, it will return the cached results. If not, it will fetch the data from the database, store it in the cache, and return the results.
  2. You can also use other cache methods provided by Laravel such as remember() to simplify the caching logic. Here's an example using remember():

public function getData()
{
    $key = 'cached_query_results';

    $data = Cache::remember($key, now()->addHour(), function () {
        return YourModel::where('column', 'value')->get();
    });

    return $data;
}


By using cache to store query results in Laravel, you can improve the performance of your application by reducing the number of database queries and speeding up data retrieval.
