PHP mail function 'from' address

Question

I\'m not even sure this is possible, however what I\'m trying to do is as follows. I have an HTML form that generates and email using a PHP script. What I want

Answer 1

Any reason you cant do it in the email headers?

$to      = 'hello@hello.com';
$subject = 'my subject';
$message = 'hello';
$headers = 'From: '.$email_from_form. "\r\n";

mail($to, $subject, $message, $headers);
