- How to use Union Types to provide stricter type detection in PHP8?
- How to use UnionTypes to provide stricter type detection in PHP8? In past versions of PHP, we did not have strict requirements on the type of variables.

This flexibility may bring convenience in some cases, but it can also easily lead to errors and hidden dangers in the code. To solve this problem, PHP8 introduced UnionTypes (union types), which allows multiple possible classes to be

- How does PHP8 handle polymorphic function parameters better via Union Types?
- How does PHP8 handle polymorphic function parameters better via UnionTypes? Before PHP8, dealing with polymorphic function parameters was a relatively complex problem. Since PHP is a dynamically typed language, function parameters can accept values of any type. This means that the parameter types of the function may be inconsistent, resulting in a lot of type checking and conversion operations required inside the function, making the code verbose and difficult to maintain. However, the concept of UnionTypes was introduced in PHP8, providing us with a better
