Global regexp search/extract

[Anon]

Hello all.

I have a plain text file which contains (amongst other things) a number of email addresses.
I want to extract these addresses out of this text file and into an array for future use (eventually creating a CSV list).

I've tried using the following regexp with the eregi function to grab the addresses:

[a-z0-9-]+(.[a-z0-9-]+)@[a-z0-9-]+(.[a-z0-9-]+)

however this only extracts the first address from the file.

If I use preg_match_all then I get the following error:

Warning: Unknown modifier '+' in C:\httpd\HTDOCS\emails.php on line 23

Any ideas as to how I can get all the addresses out of the file?

(FYI, I'm using PHP 4.0.4pl1, with PCRE enabled and version 3.1 of the PCRE library.)

Thanks in advance!

Regards,

Nathan Pace.

Are you walking through your file executing the regexp for each line?

an other method to look for is sscanf()
