What is the scope of the properties of an object?

Question

For example: The properties of the object are not declared with var in front. Is it global or local? Or is it scope-agnostic?

Answer 1

Var can be omitted in php, it has nothing to do with global and local matters

Answer 2

If you don’t add var, it will default to var. Generally, it will be declared, which is more standardized
