• Exception handling pattern

  - by treefrog

  It is a common pattern I see where the error codes associated with an exception are stored as Static final ints. when the exception is created to be thrown, it is constructed with one of these codes along with an error message. This results in the method that is going to catch it having to look at the code and then decide on a course of action. …

  - by haudenschilt

  I'm doing a security audit on a fairly large php application and was wondering where I should include my user-input validation.
