In PHP, how do I deep copy strings with strong typing?

In PHP, deep copying strings is straightforward because PHP uses a copy-on-write mechanism for strings. This means that when you assign a string variable to another, you get a copy of the original string, ensuring any changes to the new variable do not affect the original. Below is an example demonstrating this behavior.
