php scripts cannot auto execute it only execute if there is request made to them..

a simple idea in your case could pe

1.write a php function with the logic to see if filesystem has changed and do the necessary

action(email/database update) on execution.

place & call this function on your home page(index.php).

you can have cronjobs to automate execution

it's not possible with every hosting provider so i will not suggest it a fullproof method

True, but including in the index.php onevery request is bad. Use a little javascript that calls your 'cron.php' async. Just like drupal does it. this willl make sure that your users accessing your site do not notice a performance difference
