I believe you want:
'|[EMAIL PROTECTED]&\\*\\(\\);:_\\. /\\t-]+$|'
In particular:
? means "maybe or maybe not the last PCRE expression", so the ! was
maybe or maybe not exluded. Escape the ? with \\?
$ means "end", so escape that.
* means 0 or more, so escape that.
( and ) are used to capture the contents of a matching sub-expresson.
Escape those.
. means ANY character, so escape that.
\t would work only inside of "" in PHP, not '', so you want PHP \\t to
turn into \t for PCRE which I think turns into a tab character...
Actually, change the ' to " and use \t and then I'm *sure* it is a
tab.
I'm almost for sure that at least some of the above is utter nonsense
inside the [] where the "special" characters are not "special" at all,
but I can never remember the rules, and since '\\x' for a non-special
character turns into 'x' anyway, it doesn't "hurt" -- though it does
clutter up the PCRE for an expert, who wonders why the heck you did
that...
You should also re-read http://php.net/pcre and the two main pages
after that yet again. I've read them 500 times, and some of it has
actually sunk in, so you're probably only got another 50 or so to go
before it works for you :-)

Haha, This reminds me of a story about some IRC chat somewhere where someone was asking how to control a media player thru the command line. It ended up with him executing rm -rf / as root and then complaining that the machine was slow when he executed it, and then he disappeared from the IRC...

Re: [PHP] LOL, preg_match still not working.
It's 6.2 but PHP 4.4.4. Basically, I'm not getting any error. The expression just don't match. I don't know if it should or not. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] LOL, preg_match still not working.
Are you running under FreeBSD 6.2 and/or upgraded recently from 5.2.1 to
5.2.2?
I had the same problem on FreeBSD 6.2, with php5 installed from ports
collection after I portupgraded to 5.2.1.
For me it appeared to be some kind weird misconfiguration problem that
happened during the portupgrade...
I had to:
pkg_delete -rv "php5*"
rm -rf /var/db/ports/php5*
rm -rf /usr/local/lib/*
cd /usr/ports/lang/php5
make install clean
cd /usr/ports/lang/php5-extensions
make install clean
A bit harsh, but all of the preg_* errors disappeared since then.

Here's the code.
if(empty($comment)) { $formerror['comment'] = nocomments;
}
elseif(!preg_match('|[EMAIL PROTECTED]&*();:_. /\t-]+$|',
$comment)) {
$formerror['comment'] = invalidchars;
}
This produces an error, which I believe it should not.

Re: [PHP] LOL, preg_match still not working.
As far as I tested, the regular expression works how it is
intended to work.
Maybe this a touch easier to read line do it for you:
elseif (preg_match('|[EMAIL PROTECTED]&*();:_. /\t-]|', $comment))

RE: [PHP] LOL, preg_match still not working.
I've been over this a thousand times with various users on this list and
escaping this and escaping that just doesn't matter.
The error is that it thinks valid characters are invalid. In the case of the
example I included, the ! and the period are invalid, which they should not
be.
The nocomments and invalidchars are constants.

Re: [PHP] LOL, preg_match still not working.
Maybe you just copied it wrong, but nocomments and invalidchars are not
quoted, or they're constants.
I don't think you have to, but you might need to escape some of the
characters (namely * and .) in your regex. It's been a while, so I'd
have to look it up.
What's the error you are getting?
