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/.
