- How does PHP8 restrict the type of variables more strictly through Union Types?
- How to restrict the type of variables more strictly through UnionTypes in PHP8? In past PHP versions, the type of variables was relatively free. We could assign different type values to a variable, which may lead to type inconsistencies in the program. Fortunately, PHP8 introduces UnionTypes (union types), which can more strictly limit the types of variables and improve the robustness of the code. What are UnionTypes? UnionTypes indicates that a variable can accept multiple

- How does PHP8 use Stringable Interface to handle various types of strings?
- How does PHP8 use StringableInterface to handle various types of strings? PHP8 introduces a new interface Stringable, which can help developers process various types of strings more conveniently. In the past, we usually used the is_string() function to determine whether a variable is of string type, and then perform corresponding operations. Now, with the Stringable interface, we can handle strings more intuitively without having to determine their type.
