Google Alert to Mysql

I have many g o o g l e alerts, those alerts are sent to a g m a i l account. I need a PHP script that will be able to read those emails extract the information, and put it in a MYSQL database. Considerations. 1) The minimun information i require is : A) date of Alert B) Complete description for the g o o g l e alert C) link that point to that information in the web 2) The php script has to run in automatic way with a cron 3) Your solution can be implemented to go directly to my g m a i l account or if you want I can use Kettle from pentaho . org to get those emails in txt in a directory 4) If you want you can use something like GmAtom class or libgmailer
