preg_match help

[afrojojo]

I am trying to search an email header for the email address after it was piped to the script.

 

This is what the header and code look like:

 

Header

From [email protected] Sun Feb 14 17:45:41 2010

 

Code

if (preg_match("/^From (.*)/", $lines[$i], $matches)) {
$from = $matches[1];
}

 

Outputs "[email protected] Sun Feb 14 17:45:41 2010"

 

I want it to output just "[email protected]"

 

Any Ideas?

/^From (\S+)/ this will put the address at [1]

Bare in mind that will only work if a name hasn't been included in the From header. If that's not a problem then your good to go, if it is let us know. I'm not going to sit here and work something out if it's unneeded.

What if the header looks like this and is in an $email variable:

 

Header

From [email protected] Mon Feb 15 11:34:42 2010 Received: from xx-xx-xx-xx.dhcp.eucl-nbb.wi.charter.com ([xx-xx-xx-xx] helo=[xx-xx-xx-xx]) by xx.xx.com with esmtpa (Exim 4.69) (envelope-from ) id 1Nh5mL-00035o-Ti for rsv

 

Code

if (preg_match("/^From (\S+)/", $email[$i], $matches)) {
$from = $matches[1];
}

 

It doesn't output anything. I want it to output "[email protected]".

Do you have an $email array and is $i a valid key in it? If so, just echo $from.

No, email contains that header string. I'm not sure where $i comes from. echoing $from doesn't show anything. I don't fully understand preg_match, sorry.

If your not sure where it's from, why is it there? Of course it doesn't output anything, hence the fact I had the big fat if at the start of my post. If $email contains the header then it should be...

 

if (preg_match("/^From (\S+)/", $email, $matches)) {
   $from = $matches[1];
}

Yeah, im an idiot. Thanks
