Are there any security considerations to keep in mind when using objects in PHP sessions?

When using objects in PHP sessions, it is important to consider security implications such as object injection attacks. To prevent this, always serialize and unserialize objects before storing and retrieving them from sessions. This helps prevent malicious users from injecting harmful objects into the session data. 

// Storing object in session
$object = new MyClass();
$_SESSION['myObject'] = serialize($object);

// Retrieving object from session
$object = unserialize($_SESSION['myObject']);
