PHP form send email to multiple recipients

Question

I have some PHP code that I'm using to send a form off to a specific e-mail address. However, I'd like to include a couple more e-mail addresses in the PHP for when it sends it. How can I do that?

<?php if(isset($_POST['email'])) {      // EDIT THE 2 LINES BELOW AS REQUIRED     $email_to = "[email protected]";     $email_subject = "MVP Nomination";       function died($error) {         // your error code can go here         echo "We are very sorry, but there were error(s) found with the form you submitted. ";         echo "These errors appear below.<br /><br />";         echo $error."<br /><br />";         echo "Please go back and fix these errors.<br /><br />";         die();     }      // validation expected data exists     if(!isset($_POST['username']) ||         !isset($_POST['body'])||         !isset($_POST['email'])) {         died('We are sorry, but there appears to be a problem with the form you submitted.');            }      $username = $_POST['username']; // required     $body = $_POST['body']; // required     $email_from = $_POST['email'];         // required    $error_message = "";     $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';   if(!preg_match($email_exp,$email_from)) {     $error_message .= 'The Email Address you entered does not appear to be valid.<br />';   }     $string_exp = "/^[A-Za-z .'-]+$/";   if(!preg_match($string_exp,$username)) {     $error_message .= 'The Username you entered does not appear to be valid.<br />';   }    if(strlen($error_message) > 0) {     died($error_message);   }     $email_message = "Form details below.\n\n";      function clean_string($string) {       $bad = array("content-type","bcc:","to:","cc:","href");       return str_replace($bad,"",$string);     }      $email_message .= "Name: ".clean_string($username)."\n";     $email_message .= "Comments: ".clean_string($body)."\n";   // create email headers $headers = 'From: '.$email_from."\r\n". 'Reply-To: '.$email_from."\r\n" . 'X-Mailer: PHP/' . phpversion(); @mail($email_to, $email_subject, $email_message, $headers);   } header("Location: ThankYou.html");  //Redirect to Thank You HTML page after email is sent ?>​ 

Thank you.

This will work:

$email_to = "[email protected],[email protected],[email protected]";
