What is session in laravel Framework?

Sessions are used to store information about the user across the requests. Session can be configured in the file stored at config/session.php.

Sessions are a way to store data for each HTTP request with a unique session ID.

There are two methods to set the value in the session.

  • session helper function session().
  • use the Request instance to set the value in session.
    • // Global helper function
    session(['key' => 'value']);


    ############## OR #########


    // Request class instance
    $request->session()->put(['key' => 'value']);


    ############## OR #########


    // Pusing Value to Session Array
    $request->session()->push(['key' => 'value']);

    Import session in controller

    use Illuminate\Support\Facades\Session;
    use Session;

    Accessing Session Data

    To access the session data, we need an instance of session which can be accessed via HTTP request. After getting the instance, we can use the get() method, which will take one argument, “key”, to get the session data.

    File name : index.php

    // Global helper function
    $value = session('key'); br/>

    ############## OR #########


    $data = $request->session()->get('key');


    ############## OR #########


    You can use all() method to get all session data instead of get() method


    $data = $request->session()->all();

    Storing Session Data

    Data can be stored in session using the put() method. The put() method will take two arguments, the “key” and the “value”. or the session helper:

    $request->session()->put('key', 'value');

    $email = $request->input('email');
    $request->session()->put('username',$email);
    $username = $request->session()->get('username');


    // Via the global helper...
    session(['key' => 'value']);

    How to print session data on view page

    File name : index.php

    <label>
    {{Session::get('userkey')['username']}}
    {{Session::get('userkey')['userid']}}
    </label>

    Deleting Session Data

    The forget() method is used to delete an item from the session. This method will take “key” as the argument.

    $request->session()->flush(); // it remove the all session data
    $request->session()->forget('username'); // it remove the single session data

    // Forget a single key...
    $request->session()->forget('key');

    // Forget multiple keys...
    $request->session()->forget(['key1', 'key2']);

    Session::forget('your key') // Removes a specific variable

    How to check session is exist or not

    if (session()->has('userkey')) {

    if (!$request->session()->exists('user')) {
    // user value cannot be found in session
    return redirect('/');
    }


    // Checking if a session value exist

    if ($request->session()->has('key') {
    //
    }
