title: php header() syntax for meta name & content
body: <p>I've been trying to get the php header() to work with the following meta tags:</p>
  
  <pre><code>&lt;meta name="viewport" content="width=device-width, initial-scale=1.0"&gt;
  </code></pre>
  
  <p>and whatever I try, I just cannot get this to work.  I'd like to add this in addition to <code>header("refresh: 15; url=/about.html");</code> - which does work - so that the view is decent on a mobile device.</p>
  
  <p>I'm also curious about:</p>
  
  <pre><code>&lt;meta name="initial-scale=1.0, maximum-scale=1.0, user-scalable=no" /&gt;
  &lt;meta name="HandheldFriendly" content="true" /&gt;
  </code></pre>
  
  <p>In my feeble attempts to get this to work, I've tried adding</p>
  
  <pre><code>header('Cache-Control: no-cache, no-store, must-revalidate');
  header("X-UA-Compatible: IE=edge");
  header("Content-Type: text/html; charset=utf-8");
  </code></pre>
  
  <p>thinking this might cause or at least contribute to the problem, but no luck.</p>
  
  <p>I'd greatly appreciate any feedback or suggestions.</p>
  
  <p>Thanks a ton!!</p>
