Add multiple email addresses to php form_email script

Hello,

I am making a custom form for a client, and I need to send it to multiple email addresses (due to some unfortunate events and the stubbornness of someone financially involved in the project, letting 1 email address forward to the others is not an option).

Here is my code:

if(isset($_POST['email'])) {

    $email_to = "recruiting@truckingcompany.com";

Is this as simple as just using a comma or bar to separate the email addresses within the parenthesis?

I am as novice as novice gets when it comes to PHP, but I will happily offer free internet marketing consulting (my area of expertise) to anyone who is able to help me get this straightened out.

Thanks in advance.

Comma separating email addresses should work fine
