Hello folks, I need to call a php cron job to do this: 1. Web scrap currency rate for the chilean peso (i.e. google: '1 usd to clp') from any reliable currency exchange server. (Google seems good to me) 2. Check if the extracted rate from previous step exists in a table called 's_crate' with columns: 'date' and 'usd' 3. If it doesn't exist, insert a row with current date and exchange rate ('2010-08-28' and '505.05') That's it! Keywords: MySQL, Web, PHP, Scraping
