How to monitor some websites continuously and perform actions regularly

What I want to do is to post my question on a forum (e.g. Stack Overflow) and have a program concentrate on it. When someone have post their answer or reply on my post, then the program will send me an email to inform me.

One way that I could think of is to perform it using PHP with file_get_contents or curl. Keep fetching the content of the website regularly, when the number of posts / reply is changed, then send an email to me. I know that way is quite stupid so I would like to know if there are any other ways to do it.

I prefer using PHP, but if there are any other programming language which can achieve that goal are also welcome.

If the given website has an API, you can use it and create a PHP script that would fetch the required content of the given site. If it doesn't have an API, you can simply file_get_contents() the URL and check if there are changes. Directly scraping the website is generally regarded as a bad idea and hence I don't recommend it.

Once you have the script up and running, you can schedule it as a cronjob and have the script run at regular time intervals.

As for sending emails, you can use PHPMailer of SwiftMailer -- both are excellent tools to send emails from within a PHP script.
