Level 58
To replace a specific key in a session array, you can retrieve the session data, modify the specific key, and then store the modified data back into the session. Here's an example:
$key = 'my_session_key';
$session_data = session($key);
$session_data['value2'] = 'new data';
session([$key => $session_data]);
In this example, we first retrieve the session data using the $key variable. We then modify the value2 key to contain the new data. Finally, we store the modified data back into the session using the session() helper function.
