Is there any rationale for the lack of local constants in PHP? The last few years, PHP has basically exploded with lots of modern language constructs that makes the life easier. But local constants are still missing, and I find that very strange. I have found many questions online that asks for this, so it is obviously something many programmers want. Just fo... (more) |

I don't see where this comes from. Regardless of the any ones opinions of NobleZarkons complaints, their experience is real, and if one person complains about this, it is very likely that there are many others who feel the same way. And sure, since it's people who put in their free time to do this, t... (more) |

Yep, I agree that it could be hard to suggest alternatives. However, as it is now your post gives the impression that finding a replacement is trivial. I think you should at least mention that this can be somewhat tricky. Especially in a portable way.
And another thing. You're referring to a quest... (more) |

I think this post would benefit a great deal with more suggestions of alternative. After all, you're saying that the most common print function - `printf` - should not be used. Many people don't even know about anything else. (more) |

In the case that it would mean a catastrophe if the programmer forgets to do the null check in the right place, it makes total sense to have a check in the wrong place. (more) |

I find this very dogmatic. "Never" is a very strong word. As someone said: "Blindly following best practices is not best practice."
However, I can agree that it seems a bit point(haha)less for two reasons.
1. There is rarely a good way to recover is a NULL pointer is passed.
2. NULL is basica... (more) |

@#53185 We ended up using something anyway, and I got pretty good argument from my boss about it. Firstly, our requirements are stricter than the ldap server. We don't care if they match to 100%. The only thing we care about is that those that the check lets through to the server are 100% guaranteed ... (more) |

I think the first half of your answer would be better if it was a comment thread on the answer, because that's what it is. :)
Fixed the type issue. When it comes to using Set, that fell into the category "I know, but it's not important enough to care about". Did that change too.

When I saw what you wrote I thought "Omg, that's so obvious", but unfortunately, B does not have a default constructor :(

In the real code, A::add calls B::add. I want to intercept this and make A::add call BMock::add instead.
And yes, A::add is being called multiple times. Well, actually it's kind of that I call A::import, which in turn will call A::add multiple times. So there is a bit of nesting here. (more) |

Using protected made a lot of sense, and that's what I ended up doing. Also mocked a lot. (more) |

My first reaction to this was what you wrote in the second post. It's just that kind of clever code I'm trying to avoid.
It's often the case that I think code is too airy. Sometimes it makes sense with dense code. Because having to scroll back and forth when reading code can be extremely distr... (more) |

@#53078 Thanks for your input. And yes, I agree to 100% that less lines isn't necessarily better. But there are cases where it is. On the contrary, I'd say that more abstractions, less duplication and big dose of "best practice" isn't necessarily better either.
Oneliners isn't the main goal. Well... (more) |

Look at this for instance:
Foo a;
a = new Foo(); a.setX(42); assertEquals(13, bar.fun(foo).getY());
a = new Foo(); a.setX(43); assertEquals(10, bar.fun(foo).getY());
a = new Foo(); a.setX(44); assertEquals(16, bar.fun(foo).getY());
a = new Foo(); a.setX(47); assertEqua... (more) |

I completely understand your skepticism, and don't get me wrong. In many (most) cases what you're saying here is the correct approach. I'm just investigating options for when I want another option.
I do make changes to the code for testing. But almost never something that would not also make sens... (more) |

@#53305 Yes, I actually saw that.
I agree with what they say in the accepted answer. That private methods should be considered implementation details in general. But reality does not follow the books unfortunately. In my case, `foo` has a very simple, yet very distinct task. It's job is to validat... (more) |

@#53305 Yes, you're completely right. I'm looking for a mocking solution now. However, I would still like to be able to test this separately. Mainly because some tests will go very quick to run, and can be executed as part of the build process. But other tests will be to much of a slowdown. (more) |
