In WordPress, objects are passed by value or by reference

In WordPress, all objects are passed by value.

In WordPress, objects are typically passed by reference. This means that when you pass an object to a function or assign it to a variable, you’re working with a reference to the original object rather than a copy of it. Any changes made to the object within the function or variable will affect the original object.

However, it’s essential to note that PHP, the programming language on which WordPress is built, handles objects by reference by default. So, this behavior is not unique to WordPress but is a characteristic of PHP itself.
