article summarize script

I need you to develop some software for me. I would like this software to be developed for Linux using PHP.1. Need a script that pulls articles from MySQL and summarizes them into 500 - 700 text, keeping the same relevant topic of the article just summed down 2. There's dozens of websites that use this for free however I need one that runs specifically on my servers mysql table outputting to the table. There's hundreds of articles so I need the script to run via cron everyday (example) [login to view URL] [login to view URL]
