Check if new version available?

In the meantime, the User Guide is a fairly static piece of documentation - you could easily parse both the current version and change log from the CI.com user guide pages. I can pull the most recent version with three lines of code.

Code:

$html = file_get_contents('http://ellislab.com/codeigniter/user-guide');

preg_match('/<h1>CodeIgniter User Guide Version ([0-9\.]+)<\/h1>/', $html, $match);

$latest_version = $match[1];

Yes. I am using the same method for now. But what about if someone decide to change the raw html of user guide, or main site? I think it is not reliable. After all we will rely on this information that we grab.

What about if I create an automatic update library. It will rely on title of the user guide. And someone decide to change title to "CodeIgniter User Guide - Version 2.0.2". What happens? No one can know for sure. There could be an error that ruins all project. Because I am trusting it to update project core files. This error could delete all project.

Thanks.
