Get who email is to

[The Little Guy]

I am reading an email, I have this:

 

$lines = explode("\n", $this->email);
foreach($lines as $line){
if(preg_match('~^to:.+?[\<](.+?)[\>]$~i', $line, $matches)){
	$this->to = trim($matches[1]);
}
}

 

What I would like it to do, is find a "to" line in the header, and get who it is to.

 

My problem is that some emails have 2 (maybe more) "to" lines, I want to extract just the email address, how can I do that?

 

Some values:

- To: First Last <email@email.com>

- To: email@email.com

Something along the following lines should do the trick...

 

$pattern = '#^To:([a-z ]*)? <?([a-z0-9._-]+@[a-z0-9.-]+\.[a-z]{2,4})>?$#i';

 

NB(s): I capture the name meaning e-mail would be in $matches[2] if you don't need this you can remove the capture group. The pattern for matching an e-mail is rudimentary and can be improved on, technically speaking it won't work on all 'valid' e-mail addresses, but it will work on a high percentage.
