Scheduled cron job to check for pending activity
<p>Using PHP ...</p>

<p>This is for my personal use so I'm thinking maybe 3-4 emails a day.
I'm at a point where I can send an email to a dedicated email address where my script parses the message and stores it into a DB. Now, I need to figure out the best way to check the records in the DB for any upcoming task. I feel like I'm missing something, maybe like a trigger field as to when a reminder should go out. However, that's not a concern to me at the moment since I'll just send an alert 15 mins prior to the due date. </p>

<p>Question is, shoudl I run a cron job that queries the DB every minute? I take it the query will have to say something like "select all tasks that is due within 15 minutes." </p>
