What is Eloquent in Laravel?

Eloquent is Laravel's built-in ORM (Object-Relational Mapping) that allows developers to interact with a database using PHP objects instead of writing raw SQL queries. Eloquent provides a simple, expressive syntax for queries, relationships, and data retrieval, making it easy to work with databases in a more efficient and organized manner.

How to use caching in Laravel?

In Laravel, you can use caching to improve the performance of your application by storing frequently accessed data in memory or disk, so it can be retrieved quickly without having to generate it again.

Here's how you can use caching in Laravel:

1. Set up the caching driver: Laravel supports multiple cache drivers such as file, database, Redis, Memcached, and more. You can set the default cache driver in the config/cache.php configuration file.
2. Cache data: To cache data, you can use the Cache facade in your code. For example, to store some data in the cache for 60 minutes, you can do:

1

Cache::put('key', 'value', now()->addMinutes(60));

1. Retrieve cached data: To retrieve data from the cache, you can use the get method of the Cache facade. For example:

1

$value = Cache::get('key');

1. Check if data exists in the cache: You can use the has method to check if a key exists in the cache. For example:

1
2
3

if (Cache::has('key')) {
    // Data exists in the cache
}

1. Removing data from the cache: If you want to remove data from the cache, you can use the forget method. For example:

1

Cache::forget('key');

1. Cache tags: Laravel also supports cache tags, which allow you to group related cache entries together for easier management. You can assign tags to cached data by using the tags method. For example:

1

Cache::tags(['posts', 'comments'])->put('key', 'value', now()->addMinutes(60));

1. Using cache in views: In your Blade templates, you can use the @cache directive to cache a section of the view. For example:

1
2
3

@cache('key', 60)
    <p>This content will be cached for 60 minutes.</p>
@endcache

By using caching in Laravel, you can significantly improve the performance of your application by reducing the time it takes to generate and retrieve data.
