Thread Rules 1. This is not a "do my homework for me" thread. If you have specific questions, ask, but don't post an assignment or homework problem and expect an exact solution. 2. No recruiting for your cockamamie projects (you won't replace facebook with 3 dudes you found on the internet and $20) 3. If you can't articulate why a language is bad, don't start slinging shit about it. Just remember that nothing is worse than making CSS IE6 compatible. 4. Use [code] tags to format code blocks. | ||

I disagree in any case. There are perfectly good reasons for someone wanting to call a variable "protected", for instance:
That makes sense. It could be clearer, and be called $writeProtected, but it's okay. So there are two problems: some blame goes to PHP not protecting keywords, and thus allowing a variable to be called $protected. And of course some of the blame falls on the programmer for actually thinking it's a good idea to use that variable name, regardless of whether it's allowed or not. Now we just had a discussion over the last two pages, and shitty unthinking programmers will be a reality forever, so ffs, make your language more stupid proof than that. C has the excuse that it was invented in the 60s. Back when most programmers were still, essentially, rocket scientists. | ||

Another option is software dev (and 2 courses you can choose from the list I mentioned). A reasonable choice. And, if you do end up really truly wanting to go into game dev later, you can always do so. If you get a solid grounding, you can pick up game-specific stuff later (or even on the job). But, if you study purely game dev from the get go, you're backing yourself into a (potentially very underpaid) corner. | ||

Sure, game dev is something I really want to do but I think it's unwise to limit your options in the IT sector or any sector in general. | ||

It depends on the content of the course. I did a software engineering degree that was purely focused on game dev, and feel it gave me a pretty good grounding for doing non game dev work. I did have an advantage over my classmates though, in that I managed to score a part time job during my 2nd year where I got to do a lot of SQL and web stuff that wasn't really covered. The other stuff about being underpaid etc is pretty accurate though, although I've managed to end up at a studio where the pay is pretty decent compared to some of the other local options. | ||

This: http://www.digitalartsandentertainment.be/page/14/Course overview doesn't look like a normal software engineering program with a focus on game dev. | ||

It compiles fine. :D Meh. Of course you shouldn't do it, but there's worse. Essentially, any unicode character (including unicode escapes) in the character classes Lu, Ll, Lt, Lm, Lo, Nl, Mn, Mc, Nd, Pc, and Cf. The first letter is an exception and it must be a letter (classes Lu, Ll, Lt, Lm, or Lo) or an underscore. Also, if the identifier is a keyword, you must stick an @ in front of it. The @ is optional otherwise. Source: stackoverflowIf you look up those character classes (there are links on the stackoverflow page), you'll find some crazy stuff. And I've thrown a dll into dotPeek and found class names that apparently used one of these characters that is or looked like a period (or dotPeek does weird things, but in this case I'd err on the side of the dll being weird). Also don't forget that keywords may be context-specific. If you rename a variable with ReSharper to "group", ReSharper turns that into "@group" because that's a keyword for LINQ. But in most cases you can just skip the @ and call your variable "group" anyways. | ||

I mean obviously it's slightly shorter than it's "if" counterpart and arguably slightly more readable, but it just seems to add another thing to remember how to do lol. | ||

Our current codebase has at least 2000 uses of compact ternary and many, many more verbose. I'm looking forward to when my company upgrades to PHP7 and I get to use ?? too. | ||

And I keep seeing this in examples for putting variables into strings return "%d or %s put the variable into the string" %variablename Can someone explain what the benefit of doing this is, compared to: return variablename+" put the variable into the string" | ||

Is it taking the provided list and putting it into them braces based on index of the list in example 2? And I am guessing example 1 just defaults to putting them in based on the order of the braces? edit: thank you  | ||

I'm looking forward to when my company upgrades to PHP7 and I get to use ?? too. ?: is the bomb. Null coalesce will be big in 7, so will be the spaceship operator. I don't mind regular ternaries that bad, but there are cases (and I come across them frequently) when it's disastrous...
Ugh! I cringe every time when I see it. I have absolutely no idea why would anyone want to do it this way, but it's there.

The problem with "+" operator here is that sometimes variable being cast to string won't be what you expect and you'll get corrupted output. In general, you should make your string concatenation as explicit as possible to avoid such errors. | ||

But then it'll return true when you do isset($someVar) later on if $someObject->someMethod() returns null, 0, empty array or false (since you'll set $someVar to be an empty string), the code above returns false (since the variable was never declared). I know, it's stupid to use it this way (rather obscure way of declaring + instantiating a variable only if you can assign something to it) and it boggled my mind on a multitude of occasions... Figuring out that an empty string there was basically a "do nothing" clause was a true revelation. That's what you get when you're working on a code written by a lazy person who can't for the life of them be explicit.  Example:
Result:
Mindblowing, isn't it? I'm wondering to this day why use an empty string there instead of false or null though. Would be slightly bit more intuitive (but still very bad). Of course, those two are equivalent:
