Question

Parser from site to site

Answer 1

Beltoev wrote everything correctly. For implementation, you can use any ready-made libraries, for example, simplehtmldom.sourceforge.net

Answer 2

What exactly is causing the difficulty?
It's like a banal algorithm:
This is an example of the simplest parser.
Further, you can increase the functionality (automatic detection of new articles on the site using cron, uploading images to your server and replacing links to them in articles, or replacing links to images using .htaccess
, etc., etc.) there are ready-made libraries for this, but it's not so difficult to do it yourself
