You need have this two files in same folder.

• old.json
• scriptForCron.php

In scriptForCron.php write:

$url='http://media1.clubpenguin.com/play/en/web_service/game_configs/paper_items.json';
$ch = curl_init($url);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
$execute = curl_exec($ch);

$fp=fopen('old.json','w+');
$oldjson=fread($fp,filesize('old.json'));

if($execute!=$oldjson){
 mail('your@mail.com','Yoohoo', 'File changed');
 fputs($fp,$execute);
}
fclose($fp);

And then add scriptForCron.php to cron job. You can ask hosting support for it.
