PHP Scraper Script for Backpage.com

I need a simple scraping script written in PHP to scrape data from sample site [login to view URL] and then do the following with the data scraped: 1) Take the title, reply email (if it exists), description and photos (if they exist). 2) I will be running the script on a cronjob every 5 minutes, so the script needs to check to make sure an identical post does not get added twice. 3) Upload the photos for each post into a folder. 4) Insert the above information into a mySQL database (separate table for the pictures) 5) Will need to crawl the link and download the entire ad 6) repeat for entire section Essentially I want to be able to scrape the complete post and put it into my mysql database.
