I have made a session management library in PHP that stores session data in databases using functions rather than the trivial $_SESSION['key'] = value.
To store the data, the user would use storeData($key, $value) function
To retrieve the data, the user would use getData($key) function.
However I want my users to still keep using $_SESSION rather than functions so that old codes do not need to be modified.
Is there a way that if the user uses $_SESSION, I can somehow get those values and apply to my functions. So the user still would think that they are using PHP's $_SESSION but in the background they actually would be using my functions.
