Laravel Cache : Cache is one of the important part of any framework. Cache improves the system’s performance. Laravel has powerful cache mechanism which makes it perfect. Laravel provides a unified API for various caching systems. Laravel cache config file is located at config/cache.php where you can add configurations.
Laravel supports following types of caching-

• Memcached
• Redis

Laravel Cache Syntax And Example-

Let us go step by step –

Settings –

Databse :

Add a database setup to create table which will store information for database cache-

Schema::create('cache', function($table) {
    $table->string('key')->unique();
    $table->text('value');
    $table->integer('expiration');
});

Memcached –

Add settings for memcached. Go to config/cache.php and add the memcached settings-

 'memcached' => [
            'driver'  => 'memcached',
            'servers' => [
                [
                    'host' => '127.0.0.1', 'port' => 11211, 'weight' => 100,
                ],
            ],
        ],

You can add your own host name.

Redis

'redis' => [

    'cluster' => false,

    'default' => [
        'host'     => '127.0.0.1',
        'port'     => 6379,
        'database' => 0,
    ],

],

Laravel Cache Example

Let us understand the Laravel Cache functionality with simple Example –

Laravel Cache Syntax

Cache::put(); Accepts three parameters key, value and time in minutes you want to store the cache.

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

Here is a simple example –

Laravel Create Cache Example Syntax

Cache::put(); Accepts three parameters key, value and time in minutes you want to store the cache.

Route::get('/', function()
{
Cache::put('mykey', 'Welcome to Home Page !', 1);
});

Now if you hit the rout url /URL cache will be created but you will see nothing on browser. To check the cache created go to
app/storage/cache folder and check the file created after opening the file you will see the cache data along with content “Welcome to Home Page !”

Laravel Get Cache Example Syntax

Cache::get(); Accepts one parameter key to get the created cache.

Route::get('/', function()
{
Cache::get('mykey');
});

Now if you hit the index url /URL it will return the cache data from cache file create above.

Laravel Create Cache Forever Example Syntax

Cache::forever(); If you want to keep the cache file forever means it will not expire until you delete it.

Route::get('/', function()
{
Cache::forever('mykey', 'Welcome to Home Page !');
});

Laravel Forget Cache/Delete Cache Example Syntax

Cache::forget(); is used to delete the cache created using the key. It accepts key as input parameter to remove the cache for that key.

Route::get('/', function()
{
Cache::forget('mykey');
});

Laravel 5 Print Last Query : As developer for debugging the queries we often need to print the queries executed in our program which helps us to work more efficiently. In laravel you need to enable query log DB::enableQueryLog();before the query and then you can print queries as $queries = DB::getQueryLog();

Laravel 5 Print Last Query Example And Syntax

Here is simple example of printing queries in laravel –

DB::enableQueryLog();// enable query first

    // Your queries goes here
    // ...

    // Now print Queries executed....
    $queries = DB::getQueryLog();
    foreach($queries as $k=>$query)
    {
        Log::debug(" $k Query - " . json_encode($query));
    }

Which will print all queries executed.

Laravel pagination : Pagination is used to display the dynamic data using links for dynamic results. In other framework you need to work more to implement pagination functionality. Laravel provides rich pagination functionality which you can use to generate pagination links quickly. We are going to explain the simple method to create pagination in laravel using the paginate method.

Laravel pagination Syntax And Example –

Lets create a simple pagination in laravel –

Here is we are going to add pagination in UsersController and added pagination on user’s view-

class UsersController extends BaseController {

    public function userList()
    {
        $this->layout->title = "App Users ";
        $num = 20; // no of results you want to show on each page.
        $usersList = Users::orderby('created_at', 'desc')->paginate($num);
        $this->layout->content = View::make('content.userscontent')->with('usersList', $usersList);
    }

}

Where $num is no of results you want to show on each page.

Now lets display the pagination links on view

links(); ?>

Here we have displayed the links for pagination.
