Union types allow you to specify multiple data types for a parameter or return value. Instead of relying on vague mixed types or type juggling, you can explicitly declare that a variable can accept more than one type. For instance:
function processData(int|string $data) {
// Your logic here
}

Imagine youโre writing a plugin that handles different types of data for custom fieldsโperhaps text, numbers, or even arrays. Instead of writing separate methods or overcomplicating your logic, union types let you handle this cleanly with one function.
