Double slash to prevent PHP interpreting the slashes. Also using single
quotes would be a good idea:
if (preg_match('/[\\w\\x2F]{6,}/',$a))

Hi all,
I have a simple checking like
if (preg_match("/[\w\x2F]{6,}/",$a))
as I would like to allow all "word characters" as mentioned at
http://hu2.php.net/manual/hu/reference.pcre.pattern.syntax.php
plus the '/' character, and at least 6 characters.
But it throws
Warning: preg_match(): Unknown modifier ']'
and returns false for "abc/de/ggg" which string should be okay.
If I omit the "\x2F", everything works fine but "/" characters are not
allowed. Anyone knows what I'm doing wrong? Maybe "/" characters can not
be put in patterns like this?
Thanks in advance,
Zoltán Németh
