This looks like a bug... the last row should be the same. What version of
PHP are you using? Have you checked the online bug reports?
Does not seem like a bug to me ...
What you should do to get the expected result:
Unset the variable after you don't need this reference any longer.
Ah yes... that clued me in. I disagree with the article's generalization with
respect to references since references accomplish some things that cannot be
accomplished otherwise, but even I missed the fact that the second loop was
using a variable that was a reference to the last element of the array as
created in the first loop *lol*. The user's very act of checking their results
was confounding the result... I love it :)
Re, your "...that cannot be accomplished otherwise,..." Can you provide some
examples? The only ones I've found are when using create_function() and the
arguments for callback functions. I can't even remember or find in my code an
example of my foreach()loops needed it. Seems, I recall earlier versions of PHP
[<4? ]required references for variables.
