Need a PHP script for parsing goods

I need a PHP script to parse goods from the online store to my online store. My online store is an intermediary and the prices on it should be set 10% lower than in the official store.

The parser should be launched every hour and parse the current price and current quantity of goods and bring them automatically to my site, and also must check the source site for new products and automatically add them with the status of "Disabled".

The goods available should only check the price and quantity.
