title: Using PHP inside of HTML to redirect to a random site
body: <p>I need to be able to have the user click a button, and be redirected to a random page.</p>
  
  <p>I tried putting the PHP inside of JavaScript, and that inside of HTML, like this:</p>
  
  <pre><code>&lt;script&gt;
  &lt;button onclick="var jsVar = "&lt;?php 
  $urls = array("www.site1.com", "www.site2.com", "www.site3.com","www.site4.com"); 
  $url = $urls[array_rand($urls)]; 
  header("Location: http://$url"); ?&gt;""&gt;Click&lt;/button&gt;
  &lt;/script&gt;
  </code></pre>
  
  <p>I know this may have many errors, and help is very appreciated. Thank you!</p>
