In the given code example, how can using an array instead of multiple switch cases improve the code structure?

Using an array instead of multiple switch cases can improve code structure by making it more concise and easier to manage. With an array, you can store the cases and their corresponding actions in a more organized manner, making it easier to add, remove, or modify cases without having to modify the switch statement itself. This approach also allows for better scalability as the number of cases grows. 

$actions = [
    'case1' => function() {
        // Action for case 1
    },
    'case2' => function() {
        // Action for case 2
    },
    'default' => function() {
        // Default action
    }
];

$case = 'case1'; // Set the case value here

if (array_key_exists($case, $actions)) {
    $actions[$case]();
} else {
    $actions['default']();
}
