Regex help

I need to match an e-mail address to a certain pattern.
The e-mail address is given in this format: blahblah (at) gmail.com

Here's what I have:
$regex = '#^{.+(at).+.com$#si';}
Why isn't this working?

if (!preg_match("/\w+([-+.]\w+)@\w+([-.]\w+).\w+([-.]\w+)*/",
$email))

Parentheses are special regexp characters, so you need to escape them with a back-slash if you want literal parentheses.

can you how to work with regex and what is this..

For what I was talking about, you'd need to change the "(at)" to "(at)". Beyond that, without really understanding what you are trying to do, I cannot be much more specific.

Looks like someone trying to write a script to grab email address off a site that obscures email addresses.

$regex = '#\w+\s(at)\s\w+.\w{2,4}#'; is the fix.
If you've gotten a site into a string with file_get_contents, then the tags will obscure your results. For example <p>blah (at) blah.com will not turn up results because the ^ will see '<' as the start of a result, I think... Maybe you can try stripping the tags and then using word boundaries to do that... get a second opinion on that though. I tried the above regex statement with some info that I thought you'd be trying to match data from, and it seemed to work.

<?php
$url = 'the url of the site your scraping';
$data = file_get_contents($url);
$regex = '#\w+\s(at)\s\w+.\w{2,4}#';
preg_match_all($regex, $data, $match);
print_r($match); //just for testing
?>

Please don't tell me PHP Builder is supporting mass spam e-mail scrapers. :mad:

This is a simple project that is probably in every single php book that deals with regex statements. I sincerely doubt that this is out of any malicious intent to send unsolicited e-mails. Honestly, the project is probably testing knowledge of preg_replace as well, so that he can change the matches into a format that is more desirable.
