title: Display data repeatedly
body: <p>I'm working on a website where I'm showing data from my MySQL database.
  The data in the database is added every minute and I want to print that value <strong>live</strong> on my website. 
  I'm using the following PHP code for a random number:</p>
  
  <pre><code>$randomNumber = rand(0, 1000);
  </code></pre>
  
  <p>How can i get this number to keep refreshing every minute without refreshing my browser? </p>
