Sorry, the title should be "preg_match() ignores trailing linebreak"

This is documented behaviour and consistent with every Perl-style regex 
implementation in every language. Use the 'D' modifier if you want to change that 
behaviour. See http://www.php.net/manual/en/reference.pcre.pattern.modifiers.php

eg. 

echo preg_match('~^\w$~D', "a\n");
