Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
This isn't a bug. Because the last item of the array is a reference, it remains a reference if
that array is passed to other functions.
