The task is to parse the exchange rate for today every day and add it to the wordpress record every day according to the schedule
For example: The exchange

Answer 1

I would divide the task into several stages:
- Parse the html code of the desired page . The xdan.ru/Uchimsya-parsit-saity-s-bibliotekoi-PHP-Si...
library will do. - It is necessary that a script be launched at a specific site url. For example, we create a page whose url will look like http://mydomain/abracadabra. We create a template for this page and run the parser script in it. Through this script and add it (the parsed course) to the record. - It is important that the hosting of the site has cron. What is it and how to use google it. Set the script to run at the url http://mydomain/abracadabra at the right time. Maybe every hour. ALL!
