Installation

To get the latest version of Laravel Cache, simply require the project using Composer:

$ composer require dragon-code/laravel-cache

Or manually update require block of composer.json and run composer update.

{
    "require": {
        "dragon-code/laravel-cache": "^2.0"
    }
}

Using

Keys And Tags

In addition to passing an explicit value, you can also pass objects and arrays to the keys and tags methods.

For example:

use DragonCode\Cache\Services\Cache;
use DragonCode\SimpleDataTransferObject\DataTransferObject;
use Tests\Fixtures\Simple\CustomObject;

$arr1 = ['foo', 'bar'];
$arr2 = new ArrayObject(['foo', 'bar']);
$arr3 = DataTransferObject::make(['foo', 'bar']);
$arr4 = new CustomObject();

Cache::make()->key($arr1)->tags($arr1);
Cache::make()->key($arr2)->tags($arr3);
Cache::make()->key($arr2)->tags($arr3);
Cache::make()->key($arr4)->tags($arr4);

Cache::make()->key([$arr1, $arr2, $arr3, $arr4, 'foo', 'bar'])->tags([$arr1, $arr2, $arr3, $arr4, 'foo', 'bar']);
Cache::make()->key([$arr1, $arr2, $arr3, $arr4, 'foo', 'bar'])->tags([$arr1, $arr2, $arr3, $arr4, 'foo', 'bar']);
Cache::make()->key([$arr1, $arr2, $arr3, $arr4, 'foo', 'bar'])->tags([$arr1, $arr2, $arr3, $arr4, 'foo', 'bar']);

Keys Handling

Since the main problem of working with the cache's key compilation, this package solves it.

By passing values to the keys method, we get a ready-made key at the output.

For example:

use DragonCode\Cache\Services\Cache;

$cache = Cache::make()->key('foo', 'bar', [null, 'baz', 'baq']);

// Key is `acbd18db4cc2f85cedef654fccc4a4d8:37b51d194a7513e45b56f6524f2d51f2:73feffa4b7f6bb68e44cf984c85f6e88:b47951d522316fdd8811b23fc9c2f583`

This means that when writing to the cache, the tree view will be used.

For example:

use DragonCode\Cache\Services\Cache;

Cache::make()->key('foo', 'foo')->put('foo');
Cache::make()->key('foo', 'bar')->put('bar');
Cache::make()->key('baz')->put('baz');

// acbd18db4cc2f85cedef654fccc4a4d8:
//     acbd18db4cc2f85cedef654fccc4a4d8: foo
//     37b51d194a7513e45b56f6524f2d51f2: bar
// 73feffa4b7f6bb68e44cf984c85f6e88: baz

When Enabled

Basic

By default, the cache will be written for 1 day.

use DragonCode\Cache\Services\Cache;

$cache = Cache::make()->key('foo', 'bar', ['baz', 'baq']);

$cache->put(static fn() => 'Some value');
// or
$cache->put('Some value');
// Contains cached `Some value`

$cache->get();
// Returns cached `Some value`

$cache->has();
// Returns `true`

$cache->doesntHave();
// Returns `false`

$cache->forget();
// Will remove the key from the cache.

Custom TTL

The cache will be written for the specified number of minutes, seconds or the DateTimeInterface instance.

It does not matter in which direction the time shift will be. During processing, the value is converted to the abs().

As Minutes

use Carbon\Carbon;
use DateTime;
use DragonCode\Cache\Services\Cache;

$cache = Cache::make()->ttl(10);

$cache = Cache::make()->ttl('10');

$cache = Cache::make()->ttl(fn () => 10);

$cache = Cache::make()->ttl(Carbon::now()->addDay());

$cache = Cache::make()->ttl(new DateTime('tomorrow'));

As Seconds

use Carbon\Carbon;
use DateTime;
use DragonCode\Cache\Services\Cache;

$cache = Cache::make()->ttl(10, false);

$cache = Cache::make()->ttl('10', false);

$cache = Cache::make()->ttl(fn () => 10, false);

$cache = Cache::make()->ttl(Carbon::now()->addDay(), false);

$cache = Cache::make()->ttl(new DateTime('tomorrow'), false);

By Objects And Custom Strings

You can also store all TTL values in one place - in the config/cache.php file.

To do this, add a ttl block to the file and define a TTL for the objects.

After that you can use the following construction:

use DragonCode\Cache\Services\Cache;
use Tests\Fixtures\Simple\CustomObject;

$cache = Cache::make()->ttl(CustomObject::class);
$cache = Cache::make()->ttl(new CustomObject());
$cache = Cache::make()->ttl('custom_key');

// You can also specify that these values are in seconds, not minutes:
$cache = Cache::make()->ttl(CustomObject::class, false);
$cache = Cache::make()->ttl(new CustomObject(), false);
$cache = Cache::make()->ttl('custom_key', false);

If the value is not found, the default value will be taken, which you can also override in the configuration file.

With Contract

Starting with version 2.9.0, we added the ability to dynamically specify TTLs in objects. To do this, you need to implement the DragonCode\Contracts\Cache\Ttl contract into your object and add a method that returns one of the following types of variables: DateTimeInterface, Carbon\Carbon, string or integer.

This method will allow you to dynamically specify the TTL depending on the code being executed.

For example:

use DragonCode\Cache\Services\Cache;
use DragonCode\Contracts\Cache\Ttl;

class Foo implements Ttl
{
    protected $value;
    
    public function __construct(string $value)
    {
        $this->value = $value;
    }

    public function cacheTtl(): int
    {
        return $this->value === 'foo' ? 123 : 456;
    }
}

$cache = Cache::make()->ttl(new Foo('foo'));
// TTL is 7380 seconds

$cache = Cache::make()->ttl(new Foo('bar'));
// TTL is 27360 seconds

$cache = Cache::make()->ttl(new Foo('foo'), false);
// TTL is 123 seconds

$cache = Cache::make()->ttl(new Foo('bar'), false);
// TTL is 456 seconds

Tagged

For repositories that support tagging, the keys will be saved separated by tags.

use DragonCode\Cache\Services\Cache;

$cache = Cache::make()
    ->tags('actor', 'author')
    ->key('foo', 'bar', ['baz', 'baq']);

$cache->put(static fn() => 'Some value');
// or
$cache->put('Some value');
// Contains cached `Some value`

$cache->get();
// Returns cached `Some value`

$cache->has();
// Returns `true`

$cache->doesntHave();
// Returns `false`

$cache->forget();
// Will remove the key from the cache.

To retrieve a tagged cache item, pass the same ordered list of tags to the tags method and then call the get method with the key you wish to retrieve:

use DragonCode\Cache\Services\Cache;

$cache = Cache::make()->key('foo', 'bar');

$cache->tags('actor', 'author')->put(static fn() => 'Some value');
// or
$cache->tags('actor', 'author')->put('Some value');
// Contains cached `Some value`

$cache->tags('actor', 'author')->get();
// Returns cached `Some value`

$cache->tags('actor')->get();
// Returns `null`

$cache->tags('author')->get();
// Returns `null`

See the official Laravel documentation.

When Disabled

Passing when = false will not write to the cache.

use DragonCode\Cache\Services\Cache;

$cache = Cache::make()
    ->when(false)
    ->key('foo', 'bar');

$value = $cache->put(static fn() => 'Some value');
// or
$value = $cache->put('Some value');
// Returns `Some value`

$cache->get();
// Returns `null`

$cache->has();
// Returns `false`

$cache->doesntHave();
// Returns `true`
