title: PHP form send email to multiple recipients
body: <p>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?</p>
  
  <pre><code>&lt;?php
  if(isset($_POST['email'])) {
  
      // EDIT THE 2 LINES BELOW AS REQUIRED
      $email_to = "email@email.com";

      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.&lt;br /&gt;&lt;br /&gt;";
          echo $error."&lt;br /&gt;&lt;br /&gt;";
          echo "Please go back and fix these errors.&lt;br /&gt;&lt;br /&gt;";
          die();
