Sessions provide a way to store information about the user across multiple requests. Session configuration file is stored at config\/session.php. Laravel provide various drivers like file, cookie, database, mechace \/ redis, dynamodb, array. By default, Laravel is configured to use file <\/strong>session driver. <\/p>\n\n\n\n

Interaction with the Session<\/h4>\n\n\n\n

Retrieving Data<\/strong><\/p>\n\n\n\n

There are two primary ways to access the session data in laravel: the global session <\/strong>helper and via a Request <\/strong>instance. <\/p>\n\n\n\n

To access the session data via HTTP Request, we can use the get()<\/strong> method, which will take one argument, key to get the session data.<\/p>\n\n\n\n

$request->session()->get('key');<\/code><\/pre>\n\n\n\n
When we retrieve an item from the session, we may also pass a default value as the second argument to the get method.<\/p>\n\n\n\n
$request->session()->get('key', 'default');<\/code><\/pre>\n\n\n\n
To retrieve all the data in the session, we may use the all <\/strong>method:<\/p>\n\n\n\n
$data = $request->session()->all();<\/code><\/pre>\n\n\n\n
To determine if an item is present in the session, we may use the has <\/strong>method:<\/p>\n\n\n\n
if ($request->session()->has('users')) {\n    \/\/\n}<\/code><\/pre>\n\n\n\n
Pushing To Array Session Value<\/strong><\/p>\n\n\n\n
The push <\/strong>method may use to push a new value onto a session value that is an array.<\/p>\n\n\n\n
$request->session()->push('user.teams', 'developers');<\/code><\/pre>\n\n\n\n
Retrieving & Deleting An Item<\/strong><\/p>\n\n\n\n
The pull <\/strong>method may used to retrieve and delete an item form the session in a single statement:<\/p>\n\n\n\n
$value = $request->session()->pull('key', 'default');<\/code><\/pre>\n\n\n\n
If session data contains an integer we may wish to increment or decrement, we may use the increment <\/strong>and decrement <\/strong>methods.<\/p>\n\n\n\n
$request->session()->increment('count');\n$request->session()->decrement('count');<\/code><\/pre>\n\n\n\n
We may wish to store in the session for the next request. We may use the flash <\/strong>method.<\/p>\n\n\n\n
$request->session()->flash('status', 'Task was successful!');<\/code><\/pre>\n\n\n\n
To remove a piece of data from the session. We may use forget <\/strong>method.<\/p>\n\n\n\n
$request->session()->forget('name');<\/code><\/pre>\n\n\n\n
We may wish to remove multiple keys:<\/p>\n\n\n\n
$request->session()->forget(['name', 'status']);<\/code><\/pre>\n\n\n\n
The Global Session Helper<\/strong><\/p>\n\n\n\n
You may also use the global session PHP function to retrieve and store data in the session. <\/p>\n\n\n\n
Route::get('\/home', function () {\n\/\/ Retrieve a piece of data from the session...\n  $value = session('key');\n\n\/\/ Specifying a default value...\n  $value = session('key', 'default');\n\n\/\/ Store a piece of data in the session...\n  session(['key' => 'value']);\n});<\/code><\/pre>\n\n\n\n
