Basic Session Class with PHP

Hello, I needed to use session in a small project and I wrote a class to make my job easier, we can easily use or develop it in your simple projects. Now use it how you want to use it. You can create a maximum of 2 dimensional arrays, and you won't need more in the session :)

<?php

session_start();

class Session {

    public static function get($key, $subKey = false) {
        return $_SESSION[$key][$subKey] ?? $_SESSION[$key] ?? false;
    }

    public static function create($key, $data) {
        $_SESSION[$key] = $data;
    }

    public static function append($key, $data, $singleData = false) {
        if ( !self::get($key) ) {
            throw new Exception('The session you added is not created');
        }
        if ( !is_array(self::get($key)) ) {
            throw new Exception('The session you are adding is not of array type');
        }
        if (is_array($data)) {
            $_SESSION[$key] += $data;
        } else {
            $_SESSION[$key][$data] = $singleData;
        }
    }

    public static function prepend($key, $data) {
        if ( !self::get($key) ) {
            throw new Exception('The session you added is not created');
        }
        if ( !is_array(self::get($key)) ) {
            throw new Exception('The session you are adding is not of array type');
        }
        if (is_array($data)) {
            $_SESSION[$key] = $data + $_SESSION[$key];
        } else {
            $_SESSION[$key]= [$data => $singleData] + $_SESSION[$key];
        }
    }

    public static function remove($key, $subKey = false) {
        if ($subKey) {
            if (is_array($subKey)) {
                array_map(function($k) use ($key) {
                    unset($_SESSION[$key][$k]);
                }, $subKey);
            } else {
                unset($_SESSION[$key][$subKey]);
            }
        } else {
            unset($_SESSION[$key]);
        }
    }

    public static function getAll() {
        return $_SESSION;
    }

    public static function dumpAll() {
        echo '<pre>';
        print_r(self::getAll());
    }

}

Session::create('user', [
    'name' => 'phpExample'
]);

Session::dumpAll();

Session::append('user', [
    'email' => '[email protected]',
    'surname' => 'phpExampleNet'
]);

Session::append('user', 'key', 'value');
Session::prepend('user', [
    'id' => 1
]);

Session::dumpAll();

print_r(Session::get('user'));
echo Session::get('user', 'id');

// Session::remove('user');
// Session::remove('user', 'email');
Session::remove('user', ['email', 'key', 'surname']);

Session::dumpAll();

Session::create('name', 'phpExample');

try {
    Session::append('name', 'key', 'value'); // incorrect
} catch (Exception $e) {
    echo $e->getMessage();
}

Session::dumpAll();
