如何从html中以邮件[@] domain.com格式提取电子邮件地址？

I want to extract email address from html source.

i was using below to code to extract the email address in the format mail@domain.com

function extract_email_address ($string) {
    foreach(preg_split('/\s/', $string) as $token) {
        $email = filter_var(filter_var($token, FILTER_SANITIZE_EMAIL), FILTER_VALIDATE_EMAIL);
        if ($email !== false) {
            $emails[] = $email;
        }
    }
    return $emails;
}

Now, it looks like the email is protected with [] symbol, the email address looks like

mail[@]domain.com, (Notice the @ symbol withing []). So, the above code did not help.

anybody knows answer for this question?

You could just replace [@] with @ - [ Answered by Brad].
