title: Should echoing a PHP $_GET variable remove + character?
body: <p>I have a URL string like <a href="https://example.com/path/?welcome_screen=1&amp;email_address=something+else@example.com" rel="nofollow noreferrer">https://example.com/path/?welcome_screen=1&amp;email_address=something+else@example.com</a></p>
  <p>In PHP, I call <code>&lt;?php echo $_GET['email_address']; ?&gt;</code></p>
  <p>Which produces <code>something else@example.com</code></p>
  <p>Specifically, a space instead of the + in the email address.</p>
  <ol>
  <li>Is this expected?</li>
  <li>If so, is there a way to prevent this from happening in the <code>echo</code> code above?</li>
  <li>Or should it be handled when collecting the email address somehow?</li>
  </ol>
