[PHP] Re: regular expression help!
First stripslashes() and all newlines [\n\r*]. It makes the regex much easier. $pattern= %img\x20[\w\d\=\x20]+(src=\x20*\)([/\w\d\.]+)[\\x20]*/%i; preg_match($pattern, $string, $match); If more than one in the string, use preg_match_all(). Now print_r($match); so you can see the result. Now, read the doc and see why each term is used. Note, I assumed your string can have some variation and still be W3C compatible e.g., src=. and src= , etc. You may need to be able to handle additional variations.

Re: [PHP] Re: regular expression help
Hi,
From what i can see you dont even need to call global, as your passing
variables to the function ? this could be causing the script to
confuse itself.

You were right, I removed the reference to global $mac and it started
working great. Thanks. It seems sometimes another set of eyes to catch
stuff really helps... thanks.

Not sure if anyone knows of a good way to match strings of this type...
00:02:8b:0c:2f:09
I have tried this but its not working.
!eregi(^[0-9a-fA-F]{2}\:[0-9a-fA-F]{2}\:[0-9a-fA-F]{2}\:[0-9a-fA-F]{2}\:[0-9a-fA-F]{2}\:[0-9a-fA-F]{2}$,$_POST['mac'])
Use the perl compatible regexps instead:
!preg_match('/^([0-9A-Fa-f]{2}:){5}[0-9A-Fa-f]{2}$/', $_POST['mac'])
This searches for XX: 5 followed by XX, where XX is 0-9, A-F, or a-f. I
_think_ the POSIX regexps can do some grouping like this as well, but
I'm not absolutely sure.

[PHP] Re: Regular Expression Help in my PHP! Sorry if wrong group
I figured out what I was doing wrong. My regexp should of looked like this /a[^]*(Tampa)\/a/ and that made it more specific and kept it to that match. Jason Lehman wrote: I have a script that turns certain words into links. That I am having no problems with, it is when I want to turn the links back in to plain text that I am having the problem. Below are my examples. And I know my regex is being greedy but I don't know how to stop it from being so damn greedy I thought the ? mark would help but it didn't. Any help would be appreciated. So here it goes: The code: $strStr = This is a href=testUSF/a at a href=testTampa/a. This is a href=testUSF/a at a href=testTampa/a.; echo $strStr.br\n; $strStr = preg_replace(/a.*?(Tampa)\/a/,\\1,$strStr); echo $strStr.br\n; $strStr = preg_replace(/a.*?(USF)\/a/,\\1,$strStr); echo $strStr.br\n; The output: This is a href=testUSF/a at a href=testTampa/a. This is a href=testUSF/a at a href=testTampa/a. This is Tampa. This is Tampa. This is Tampa. This is Tampa. The expected output: This is a href=testUSF/a at a href=testTampa/a.

hi all,
I have some user-supplied text on a content driven site.
I am allowing A tags inside the main text, BUT I want
any links to external sites (not on the chosen domain)
to include a ' TARGET=_new ' element.
So,
A HREF=http://www.mydomain.com/mypage.php;something/a is fine
A HREF=http://www.yourdomain.com/yourpage.php;something/a is wrong
A HREF=http://www.yourdomain.com/yourpage.php;
TARGET=_newsomething/a is fine
And of course there are all the variants with and without
the www, and with and without sub directories and pages.
I'[d also like to make sure the dopey people have put a
close tag in.
I've got a few ideas on how it might be done, but I need
to do it the right way, avoiding slight human errors etc.
Has anyone got something written, or can point me in the
right direction?

Subject: Regular Expression help
Hi everyone,
I have a new user function that checks e-mail addresses.
I wish to only allow people from two different domains to register.
How can I filter out all other e-mail addresses and return an error if
it's
not from those domains.
Here's what I have:
if ((!$email) || ($email==) ||
(!eregi(^[_\.0-9a-z-]+@([0-9a-z][0-9a-z-]+\.)+[a-z]{2,3}$,$email)))
$stop
= center._ERRORINVEMAIL./centerbr;
What this currently does is just makes sure it's a valid e-mail address.
What I'd like it to do is if the user enters anything except @domain1.com
or
@domain2.com it spits out the error (ERRORINVEMAIL)
So (I think) It would look something like this:
if ((!$email) || ($email==) || (!eregi(^[_\.0-9a-z-]+@([DdOoMmAaIiNn1]
||
(or statement???) [DdOoMmAaIiNn2-]+\.)+[a-z]{2,3}$,$email))) $stop =
center._ERRORINVEMAIL./centerbr;
Of course, this doesn't work, but you get the point.
Thanks!
P.S.
Thanks for the Awesome List!
