Copying pages from other web sites

[ditusade]

Hi,
Just wanted to know if anyone knows how to extract data on other web sites as and when they get refreshed using PHP or other tools.
E.g If I want to capture all new posting on a particular forum/feedback page and wanted to format the data for my purpose.
Any suggestions will be greatly appreciated
Thanks
Dave

to get the contents of another webpage somewhere else:

$content = file_get_contents('http://www.blah.com');

then you will need to use something like preg_match to search $content for what you are looking for.
