Parse RFC 822 compliant addresses in a TO header

Question

I would like to parse an email address list (like the one in a TO header) with preg_match_all to get the user name (if exists) and the E-mail. Something similar to mailparse

Answer 1

Finally I did it:

public static function parseAddressList($addressList)
{
    $pattern = '/^(?:"?((?:[^"\\\\]|\\\\.)+)"?\s)?<?([a-z0-9._%-]+@[a-z0-9.-]+\\.[a-z]{2,4})>?$/i';
    if (($addressList[0] != '<') and preg_match($pattern, $addressList, $matches)) {
        return array(
            array(
                'name' => stripcslashes($matches[1]),
                'email' => $matches[2]
            )
        );
    } else {
        $parts = str_getcsv($addressList);
        $result = array();
        foreach($parts as $part) {
            if (preg_match($pattern, $part, $matches)) {
                $item = array();
                if ($matches[1] != '') $item['name'] = stripcslashes($matches[1]);
                $item['email'] =  $matches[2];
                $result[] = $item;
            }
        }
        return $result;
    }
}

But I'm not sure it works for all cases.

I don't know that RFC, but if the format is always as you showed then you can try something like:

preg_match_all("/\"([^\"]*)\"\\s+<([^<>]*)>/", $string, $matches);
print_r($matches);
