Helper Functions: When would you reach for the with function?

I was looking through the Laravel docs and was wonder when someone would reach for the with() helper in a real world example.

Examples or articles welcome.

Below is the example from the docs.

$callback = function ($value) {
    return (is_numeric($value)) ? $value * 2 : 0;
};

$result = with(5, $callback);

// 10

$result = with(null, $callback);

// 0

$result = with(5, null);

// 5
