Wondering if anyone out there is experienced using PHP runner? I have built a web application which includes member details of various elements of data. I have a roster page, of which I would like to include a new field "Days lapsed" This field is to calculate automatically how many days have passed since the "Logbook Last Updated"

The logbook last update field is currently auto time and date stamping in the mysql database, each time a new record is submitted by the members.
