Hi guys.
Could someone make a really simple snippet for me that checks an online file which contains only one line. For example http://mysite.com/news.php , and all it says is - I am the new topic . So could you make it, so each 30 minutes, this script checks this website and if the line differs from the previously checked line, it changes it to the new one?

Example: if website says - I am the new topic , and the actual topic is I am very old topic, then it changes it to I am the new topic .

Thanks wink
