• php: avoiding __get in certain circumstances?

  - by user151841

  I have a class where I'm using __set. Because I don't want it to set just anything, I have an array of approved variables that it checks before it will actually set a class property. However, on construct, I want the __construct method to set several class properties, some of which are not in the approved list. So when construct happens, and I do $this->var = $value, I of course get my exception that I'm not allowed to set that variable. Can I get around this somehow?

• Is there an easy way to "append()" two dictionaries together in Python?

  - by digitaldreamer

  If I have two dictionaries I'd like to combine in Python, i.e. a = {'1': 1, '2': 2} b = {'3': 3, '4': 4} If I run update on them it reorders the list: a.update(b) {'1': 1, '3': 3, '2': 2, '4': 4} when what I really want is attach "b" to the end of "a": {'1': 1, '2': 2, '3': 3, '4': 4} Is there an easy way to attach "b" to the end of "a" without having to manually combine them like so: for key in b: a[key]=b[key] Something like += or append() would be ideal, but of course neither works on dictionaries.
