  • Are you asking why it marked 2 lines as not executed but the third line was executed? – MonkeyZeus Feb 22 '19 at 13:35
  • Yes, I am. Why? – Andrei Lupuleasa Feb 22 '19 at 13:36
  • Btw: you want to use in_array() instead of your current lenghty chain of conditions. – Marcin Orlowski Feb 22 '19 at 13:36

    You should include that clarification in your question. I would imagine that the downvotes are due to lack of clarifying your question. – MonkeyZeus Feb 22 '19 at 13:38
  • I thought it was obvious. – Andrei Lupuleasa Feb 22 '19 at 13:40

    @AndreiLupuleasa The PHP tag gets a lot of crap every single minute so relying on people to spot the "obvious" is not a good idea. I am genuinely confused why xdebug is behaving like that but I would imagine that their support channel can tell you: https://xdebug.org/support.php – MonkeyZeus Feb 22 '19 at 13:43
  • If you don't believe me about the amount of crap PHP questions then just check out how many questions have been asked since you posted this. There are 100 new questions ahead of yours. – MonkeyZeus Feb 22 '19 at 13:45
  • That almost sounds like discrimination. People don't pay attention anymore, these days. It's easier to judge than to take some time to understand. – Andrei Lupuleasa Feb 22 '19 at 13:54
  • BTW @MarcinOrlowski `in_array` is slower https://stackoverflow.com/questions/35205363/in-array-performance-optimization/35205873 – Andrei Lupuleasa Feb 22 '19 at 14:20

    Discrimination? Be my guest and open up that discussion on [Meta](https://meta.stackoverflow.com/). Everyone here volunteers their time so if you wish to make the community better then I invite you to spend more time answering questions and filtering the noise. The unfortunate fact is that for every good question there are at least 100 crap questions so selective attention and speed play a key role in volunteers maintaining their sanity. If you feel entitled to quality then please exhibit the quality which you expect. – MonkeyZeus Feb 22 '19 at 14:30
  • By the way, I am not saying that your question is bad by any means but the lack of early clarification most likely resulted in downvotes and I doubt that the view count on this will surpass 40. It's just the nature of the beast known as Stack Overflow – MonkeyZeus Feb 22 '19 at 14:34
  • @andrei sure, critically slow. Esp. With 4 elements array, lol. Read the question you link to again. He had 10k elements there. – Marcin Orlowski Feb 22 '19 at 14:47
  • @MarcinOrlowski that 4 elements array is in a loop which is in another loop so do the math. – Andrei Lupuleasa Feb 22 '19 at 14:51
  • Benchmark yourself. – Marcin Orlowski Feb 22 '19 at 14:53
  • I don't have to. There are already a lot of examples on the web. http://www.w3programmers.com/phps-in_array-function-is-really-slow/ – Andrei Lupuleasa Feb 22 '19 at 14:54

I've understood what happens. The line 586 has multiple conditions and not all cases are covered and for those cases that are not covered 587 and 588 are listed as not executed.

The legend should be updated though because is confusing.
