Mocks are used when it is necessary to verify the interactions between the system under test and test doubles. Care needs to be taken to avoid creating overly brittle tests, but mocking can be particularly useful when the method to test is simply orchestrating other calls. This test verifies that ...

The Basics The simplist way to convert one date format into another is to use strtotime() with date(). strtotime() will convert the date into a Unix Timestamp.
