php refresh on 2nd page refresh

i have this function that gives me an output of a number. (the number is my total amount of downloads from my iphone themes.开发者_开发百科) because the code has to make so many requests, it loads the page very slowly. what would be the best way for me to go about the code loading into a variable and than calling it on the second page refresh. so it dosnt take so long to load?

or any other method will do. i just want it to not take so long to load!

also this isnt on my server so i cant use $.ajax

<?php
function all_downloads() { 
 $allThemes = array( 
  'com.modmyi.batterytheme',
  'com.modmyi.connectiontheme',
  'com.modmyi.icontheme',
  'com.modmyi.percenttheme',
  'com.modmyi.statusnotifiertheme',
  'com.modmyi.cnote',
  'com.modmyi.iaccescnotekb',
  'com.modmyi.cnotelite',
  'com.modmyi.multibrowsericon',
  'com.modmyi.changeappstoreiconwithinstallous'
 );
 $total = 0;
 foreach($allThemes as $com_modmyi){
  $theme = file_get_contents( "http://modmyi.com/cstats/index.php?package=".$com_modmyi.'&output=number');
  $theme = str_replace(",","", $theme);
  $almost_done += $theme;
  $rock_your_phone = 301; //From c-note and Multi Lock Screen Theme on Rock Your Phone
  $total = ($almost_done + $rock_your_phone);
 }
 echo number_format($total);
}
?>

call the function with AJAX !

Th basic idea of using ajax is to to help make web applications function more like desktop applications

most actions that an end-user takes in his or her browser send a request back to the web server. The server then processes that request, perhaps sends out further requests, and eventually responds with whatever the user requested. <--whats your problem is ** **(slow !)

with AJAX you can call a PHP function with out reloading a page

please go though this tutorial which is really simple
