Hi! Can anyone explain me why function like print_r is not aware of object's read_property handler? What's the purpose of printing hash instead of using object's read_property standard handler or hook? When read_property hook is used then , and when it's ignored? What read_property handler hook should do , if it's ignored in functions like print_r?

In order to use read_property() you need to know the name of the property. print_r() and var_dump() output all properties of the object, they do not know their names, they have only the object itself. Therefor you need to implement get_properties() hook to return a hash table with all object properties. Which part of this explanation is not clear to you? -- Wbr, Antony Dovgal
