I need a php webscraper that will integrate with my existing web application. When a user make a search on my site I need the scraper to go out to this website (example property http://a810-bisweb.nyc.gov/bisweb/PropertyProfileOverviewServlet?bin=3000176&requestid=4) and collect data from multiple sections. This has to be done in a live instance and must be able to work with thousands of concurrent requests. I need the script to account for errors with the website loading and must know to retry that property. Second part to the script is I need to monitor that property for any key changes in data, there will be a second parameter to tell the script to do such. The data will be be inserted into a MySql database.
