title: Ajax auto update counter from different sources
body: <p>I'm using this code to get an int value from 3 different servers:</p>
  
  <pre><code>$js = file_get_contents( 'http://www.gta4.it/stat/view_stats.js.php?mode=3');
  $value = trim( str_replace( array( "document.write('", "');"), '', $js));
  
  $js = file_get_contents( 'http://www.tuttoirc.it/stats/view_stats.js.php?mode=3');
  $value2 = trim( str_replace( array( "document.write('", "');"), '', $js));
  
  $js = file_get_contents( 'http://www.thesims3.it/stat/view_stats.js.php?mode=3');
  $value3 = trim( str_replace( array( "document.write('", "');"), '', $js));
  $total =(string) ($value + $value2 + $value3); 
  $totalFormatted = number_format($total, 0, ',', ' ');
  echo $totalFormatted; 
  </code></pre>
  
  <p>and I output the sum value of all the counters.
  Is there a way to auto update the counter without refreshing the page with ajax in a fancy way? Like an "electricity counter" or some visual effect every tot seconds?</p>
