note 24578 added to ref.regex

Something that really got me: I'm used to using Perl's regexps, and so I used \s to check for a whitespace character in a password on a website. My PHP book (Wrox Press, Professional PHP Programming) agreed with me that this is exactly the same as [ \r\n\t\f\v], but it's NOT. In fact, what it did was keep anyone from joining the site if they put an 's' in their password! So beware, check for subtle differences between what you're used to and PHP. [[:space:]] works fine, by the way. I'm going to use the pcre functions from now on... I like Perl :o) -- http://www.php.net/manual/en/ref.regex.php http://master.php.net/manage/user-notes.php?action=edit+24578 http://master.php.net/manage/user-notes.php?action=delete+24578 http://master.php.net/manage/user-notes.php?action=reject+24578
