Spider App Store(repost)

I need a PHP script that crawls Apple's app store and adds the app ID's to the MySQL database. Using the app ID's, utilize Apple's Search API to get the specific information about that app and also store that in the mysql database. The download link to the app needs to be customized based on the affiliate ID. ## Deliverables More specifically, the script should do the following: 1. Crawl Apple's itunes app store 2. Check to see if that app_id is already in the database 2.1 If it is in the database, check to see when it was last updated 2.1.1 if it has been over three weeks since it was last updated, query the search api and get the data for that app and update that row in the table 2.1.2 if it hasn't been over three weeks, do nothing. 2.2 If the app isn't already in the database, check to see if it is a valid ID by using the search api and ensuring there is app data sent back to you. 2.2.1 If it is valid, add the app and its details to the database 2.2.2 if it is not valid, ignore it The time it took to run, which apps were added, which were updated, the date/time it was run, and any errors should be logged in a table.
