include_once is *not* a function so you cannot use it in the way you are attempting to.  The brackets are optional so you are really just telling PHP:

include_once "lib/file.php" . "<BR>";

i.e. concatenate the stuff at the right then include the contents of the named file.

That said, the parser should probably raise an error since technically your code is malformed due to the bracket in the middle.

So if there is any bug, it is the parser not complaining about the syntax error.

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

(And there is no parse error as the < is part of a string)
