Re: Function returning but continues execution

Yes, I know it looks like a bug in my code because I'm not able to write a test case that can reproduce it simply enough to report as a bug - hence why I am posting here. However, the behaviour I am describing surely suggests some kind of issue somewhere in PHP itself. My reasoning for this is if I echo the 2 variables I get: Array ( [0] => 3 ) and 3 and the bug appears. But if I set them manually before the in_array test: $_SESSION['user']['friends'] = array(0 => 3); $friend['user_id'] = 3; it works as expected. Am I wrong in thinking that this has to be a bug in PHP? I have used debug_backtrace() to find out what is going on as regards how many times the function is being executed - that is the first thing I checked because it does indeed suggest that it is being executed multiple times, however, the back trace only reveals 1 call/execution.

The key is that the function is returning false but it continues to execute! If I stick in an exit; after the in_array() check at point #4, this doesn't happen. There are no other places where this function is called, and it is only called once. Strangely, if I force the values of the 2 variables before the in_array() check: $_SESSION['user']['friends'] = array(0 => 3); $friend['user_id'] = 3; it reacts as expected - the function returns false and no further code is executed. Anyone have any suggestions?

You have a bug somewhere in your code.

I can't see how there is a bug in my code if when I echo the contents of the 2 variables, they are exactly the same as when I set them manually. Except in the former the function "continues executing" but in the latter it doesn't. I also cannot see how the function can return false and execute the SQl query when it is only called once.

You have presented no proof that there's a bug in the PHP. What you have presented looks like you have a bug, and the function gets called more than once. Have you used a debugger? See http://xdebug.org/.
