What potential security risks are involved in implementing a feature to simulate being logged in as another user in PHP?

Implementing a feature to simulate being logged in as another user in PHP can pose security risks such as unauthorized access to sensitive information or actions on behalf of another user. To mitigate this risk, it is important to implement proper authentication and authorization checks before allowing a user to simulate being logged in as another user. 

// Check if the current user has the necessary permissions to simulate being logged in as another user
if ($currentUser->isAdmin()) {
    // Code to simulate being logged in as another user
} else {
    echo "You do not have permission to perform this action.";
}
