Preg_Match_All Question

Hi I have a Google Checkout script that automatically logs info into a .log file. I want to make it easier for myself to view any email address' that might be there.

I know the method is preg_match_all after doing some google searching, I'm just not sure of the syntax.

Thanks so much for your help.

Depending on the format of the log, it might be easier to use something like explode rather than a regex for this. can you give the format of the log file?

Otherwise, here's the preg_match_all manual page
http://uk.php.net/manual/en/function.preg-match-all.php
and here's some regexes for email addresses

Hey, thanks for responding.

I'm still throughly confused


<?php

$addr_spec = '([^\\x00-\\x20\\x22\\x28\\x29\\x2c\\x2e\\x3a-\\x3c'.
'\\x3e\\x40\\x5b-\\x5d\\x7f-\\xff]+|\\x22([^\\x0d'.
'\\x22\\x5c\\x80-\\xff]|\\x5c[\\x00-\\x7f])*\\x22)'.
'(\\x2e([^\\x00-\\x20\\x22\\x28\\x29\\x2c\\x2e'.
'\\x3a-\\x3c\\x3e\\x40\\x5b-\\x5d\\x7f-\\xff]+|'.
'\\x22([^\\x0d\\x22\\x5c\\x80-\\xff]|\\x5c\\x00'.
'-\\x7f)*\\x22))*\\x40([^\\x00-\\x20\\x22\\x28'.
'\\x29\\x2c\\x2e\\x3a-\\x3c\\x3e\\x40\\x5b-\\x5d'.
'\\x7f-\\xff]+|\\x5b([^\\x0d\\x5b-\\x5d\\x80-\\xff'.
']|\\x5c[\\x00-\\x7f])*\\x5d)(\\x2e([^\\x00-\\x20'.
'\\x22\\x28\\x29\\x2c\\x2e\\x3a-\\x3c\\x3e\\x40'.
'\\x5b-\\x5d\\x7f-\\xff]+|\\x5b([^\\x0d\\x5b-'.
'\\x5d\\x80-\\xff]|\\x5c[\\x00-\\x7f])*\\x5d))*';

$email = "real@email.com - notavalid.email";

$output = preg_match_all("!^$addr_spec$!", $email);

echo $output;

?>



I'm getting some wild expression errors on this one.
