Laravel provides a unified API for various caching systems. The cache configuration is located at app/config/cache.php. In this file you may specify which cache driver you would like used by default throughout your application. Laravel supports popular caching backends like Memcached and Redis out of the box.

The cache configuration file also contains various other options, which are documented within the file, so make sure to read over these options. By default, Laravel is configured to use the file cache driver, which stores the serialized, cached objects in the filesystem. For larger applications, it is recommended that you use an in-memory cache such as Memcached or APC.

Cache Usage

Storing An Item In The Cache

Cache::put('key', 'value', $minutes);

Storing An Item In The Cache If It Doesn't Exist

Cache::add('key', 'value', $minutes);

Checking For Existence In Cache

if (Cache::has('key'))

Retrieving An Item From The Cache

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

Retrieving An Item Or Returning A Default Value

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

$value = Cache::get('key', function() { return 'default'; });

Storing An Item In The Cache Permanently

Cache::forever('key', 'value');

Sometimes you may wish to retrieve an item from the cache, but also store a default value if the requested item doesn't exist. You may do this using the Cache::remember method:

$value = Cache::remember('users', $minutes, function()
	return DB::table('users')->get();

You may also combine the remember and forever methods:

$value = Cache::rememberForever('users', function()
	return DB::table('users')->get();

Note that all items stored in the cache are serialized, so you are free to store any type of data.

Removing An Item From The Cache


Increments & Decrements

All drivers except file and database support the increment and decrement operations:

Incrementing A Value


Cache::increment('key', $amount);

Decrementing A Value


Cache::decrement('key', $amount);

Cache Sections

Note: Cache sections are not supported when using the file or database cache drivers.

Cache sections allow you to group related items in the cache, and then flush the entire section. To access a section, use the section method:

Accessing A Cache Section

Cache::section('people')->put('John', $john, $minutes);

Cache::section('people')->put('Anne', $anne, $minutes);

You may also access cached items from the section, as well as use the other cache methods such as increment and decrement:

Accessing Items In A Cache Section

$anne = Cache::section('people')->get('Anne');

Then you may flush all items in the section:


Database Cache

When using the database cache driver, you will need to setup a table to contain the cache items. Below is an example Schema declaration for the table:

Schema::create('cache', function($table)
