Using $_SESSION in Laravel From non-Laravel project

to access $_SESSION, simply place session_start() at the beginning of the index.php file of your laravel-project

Laravel doesn't use native PHP sessions since Laravel 5.

We are no longer using Symfony's (and therefore PHP's) session handling facilities, and are using a custom solution that is simpler and easier to maintain

In Laravel you want to use Session:: facade or session() global helper to work with sessions:

// Saving value.
session()->put('key', 'value');

// Gettinng value.
session('key');

Laravel provides more inbuilt method to get and set session data. it’s easy to working with session in laravel.A session variable is used to store some information or some data about user or anything you want to access on all pages of an application.In laravel session configuration is stored in "app/config/session.php".

I have found here a very easy tutorial to understand the usage of the SESSION in laravel which you can also find it in easy for learning.

Setting a single variable in session :-

Below is the syntax of the Session

Syntax :- Session::put('key', 'value');

Example :-

Session::put('email', $data['email']); //array index
Session::put('email', $email); // a single variable
Session::put('email', '[email protected]'); // a string

Retrieving value from session :-

The syntax for retrieving the values from the session

Syntax :- Session::get('key');

Example:

Session::get('email');

Checking a variable exist in session :-

// Checking email key exist in session.
if (Session::has('email')) {
  echo Session::get('email');
}

Deleting a variable from session :-

syntax :- Session::forget('key');

Example:

Session::forget('email');

Removing all variables from session :-

Session::flush();

you just have to use

session_start();

in your laravel code

and then

dd($_SESSION);

//it will print all keys inside sessions variable in your laravel project..
