What are the potential risks of using IP-based pseudosessions instead of traditional sessions in PHP?

Using IP-based pseudosessions instead of traditional sessions in PHP can pose security risks, as IP addresses can be easily spoofed or changed. This can lead to unauthorized access to user data or session hijacking. To mitigate this risk, it is recommended to use a combination of IP-based pseudosessions along with other secure methods, such as using tokens or encryption. 

// Implementing a more secure pseudosession using a combination of IP address and a unique token

$ip = $_SERVER['REMOTE_ADDR'];
$token = md5(uniqid(rand(), true));

$_SESSION['pseudosession'] = [
    'ip' => $ip,
    'token' => $token
];

// Verify pseudosession
if ($_SESSION['pseudosession']['ip'] === $_SERVER['REMOTE_ADDR']) {
    // Session is valid
} else {
    // Invalid session, take appropriate action
}
